He holds the FIDE Candidate Master title and has represented his country in various national and international events. He is also a FIDE National Arbiter since 2022 and a FIDE Instructor. — — He maintains a standard rating around 2055, with rapid around 1970-2000 and blitz in the 2060 range, having peaked near or above 2115 in earlier years. He is based in Santiago de los Caballeros and remains an active competitor in Dominican tournaments as well as online events like Chess.com Titled Tuesdays. — — In his chess career, Feliz Dotel has participated in multiple Dominican national championships and pre-national qualifiers, consistently placing in the mid-to-upper field among the country's active players. He has faced both local titled players and international opponents in open and team events, with notable games against stronger masters where he has secured occasional upsets or solid draws. He also serves in organizational roles, such as deputy chief arbiter in regional tournaments. — — His playing style includes a preference for offbeat and flank openings. He has employed 1.b4 (the Sokolsky or Polish Opening) with some regularity, fitting the query's suggestion, which leads to unbalanced positions that reward creative piece play and queenside space grabs rather than mainline theoretical battles. This choice aligns with his approach of steering games into less explored territory where preparation edges and practical chances matter. He also uses systems like the Reti in certain lines. — — Interesting details include his dual role as player and instructor/arbiter, contributing to chess development in the Dominican Republic through education initiatives. At around age 40, he stays competitive in a scene featuring younger talents, often delivering resilient performances in faster time controls where his blitz rating shines. His online handle Dewarfd appears on platforms like Chess.com and Lichess, where he engages in regular titled events. — — Note created May 2026. (AI)

He grew up in Madrid and began playing chess at age five, guided by his father. He studied mathematics at the Complutense University of Madrid but later focused on chess full-time, training with IM David Martνnez. He is married to Nicky Paige Antσn. — — He earned the FIDE Master title in 2009, International Master in 2012, and Grandmaster title in 2013 at age 18. His current FIDE classical rating stands at 2657, with a peak of 2703 in March 2020, when he reached world number 35 and crossed the 2700 barrier. — — Career highlights and achievements include winning the Spanish championship eight times across various age groups and formats. He secured bronze at the 2012 European Youth U16 Championship and silver at the 2013 World Youth U18 Championship. In 2014, he took silver at the European Individual Championship, which qualified him for the FIDE World Cup, and he won the Spanish Blitz Championship that year, finishing ahead of Francisco Vallejo Pons. — — Other notable results feature winning the 2016 Magistral d'Escacs Ciutat de Barcelona on tiebreak over Jan-Krzysztof Duda, placing second at the 2017 Tradewise Gibraltar Masters (after leading much of the event and defeating players like Veselin Topalov and Boris Gelfand), and tying for third to eleventh at the 2019 European Individual Championship. In January 2020, he won the Tata Steel Challengers, qualifying for the Masters group the following year. He has represented Spain at two Chess Olympiads and won the 2025 Spanish Championship with 8/9, dominating a field with seven grandmasters. — — He has participated in strong events such as the FIDE Grand Swiss, World Cup, and various invitationals, with career earnings around $170,000. A strong rapid and blitz player, he has also competed in the Champions Chess Tour. — — Preferred openings: With White, he most commonly plays the Reti System, English Opening, and Nimzo-Larsen Attack variations, along with some Queen's Pawn systems. With Black, he frequently employs the Ruy Lopez, Giuoco Piano (Italian Game), and responses to Queen's Pawn openings. He does not notably favor 1.b4 (the Sokolsky or Orangutan Opening) as a main weapon; it appears rarely if at all in his repertoire, which leans toward solid, flexible positional setups rather than flank surprises. — — Interesting details include his victory over Magnus Carlsen in at least one classical game and consistent performances against top players. Known as "El Niρo" in some circles, he maintains a professional yet approachable style, often delivering strong results in open tournaments and national events while balancing competitive play with occasional coaching or content contributions. His peak form in 2019-2020 showcased him as one of Spain's leading grandmasters alongside Vallejo Pons. — — Note created May 2026. (AI)

Narayanan,SL (2600) - Badacsonyi,Stanley (2320), Titled Tue 1st Apr Late (8), 2025. — — Sunilduth Lyna Narayanan was born on 10 January 1998 in Thiruvananthapuram, Kerala, India. He earned the international master title in 2014 and the grandmaster title in 2015, becoming the 41st grandmaster from India. His peak FIDE rating reached 2695 in March 2024, with a world ranking as high as number 40 in May 2024. As of March 2026 his FIDE rating stands at 2608, placing him around number 17 in India. — — Narayanan began playing chess as a child after watching his mother compete in a tournament. He received early training from former Kerala state champion P. Sreekumar and later from international master Varugeese Koshy, as well as grandmasters including Praveen Thipsay, Alexander Goloshchapov, and Avetik Grigoryan. He also attended a training camp with grandmaster Yevgeny Vladimirov in 2011. His family made significant sacrifices to support his chess career, with his father leaving his job to accompany him to tournaments. — — In junior chess Narayanan won the Kerala state under-9 championship in 2007 and secured multiple state titles in under-11, under-13, sub-junior, and junior categories. At the national level he won gold in the National Junior Championship in 2014. Internationally he claimed gold in the Commonwealth under-16 championship in 2012, silver in the Asian Junior Championship in 2015 and 2016, gold in the Asian Junior Blitz Championship in 2016, and bronze in the World Junior Championship in 2016 held in Odisha. He represented India on first board at the under-16 Chess Olympiad, contributing to a bronze medal for the team. — — Among his notable senior achievements are victory in the Ellobregat Open in Spain in 2019 after a playoff, a win in the Chess.com Titled Tuesday online tournament in 2019 against a strong field including Hikaru Nakamura and Wesley So, and a bronze medal in the Qatar Masters Open in 2023. He has competed in the FIDE World Cup and achieved a silver medal with the Alkaloid team in the European Club Cup in 2024. In 2017 he defeated then-reigning world blitz champion Sergey Karjakin in the Aeroflot Blitz tournament. Narayanan has also participated in club competitions and open tournaments across Europe and Asia, earning prize money estimated around 70,000 US dollars in his career. — — His playing style is described as balanced, combining solid preparation with efforts to improve weaknesses through analysis of his own games. He has shown strong handling of certain middlegame structures, such as those arising from the exchange Ruy Lopez. As black he has frequently faced the Sicilian Defense, Ruy Lopez, Nimzo-Indian Defense, and Queen's Gambit Declined. As white his games include various queen's pawn openings and other systems, though no single dominant repertoire stands out as unconventional or centered on 1.b4. He dedicates several hours daily to training, mixing study, online play, and review of classical games for deeper understanding beyond pure engine evaluation. — — Narayanan has been recognized for sportsmanship, such as declining a walkover against a grandmaster at age 11 to play the game fairly. He has contributed to chess in Kerala and India as part of the generation of grandmasters emerging from the country. He maintains a professional approach focused on reaching higher ratings and contributing to team events like the Olympiad while balancing academic excellence, having scored perfectly in his higher secondary examinations. — — Note created March 2026.

He has secured the Belarusian Chess Championship title five times. He represented Belarus in multiple Chess Olympiads, World Team Chess Championships, and European Team Chess Championships. He also participated in the FIDE World Championship cycles in 1998, 1999, 2000, and 2004, as well as the FIDE World Cup in 2017. — — Notable tournament victories and high placements include first place at Gistrup in 1996, Kstovo in 1998, the Petroff Memorial in St. Petersburg in 2000, the 17th open at Bad Wφrishofen in 2001, shared first at the Aeroflot Open in Moscow in both 2002 and 2003, the Inautomarket Open in Minsk in 2005, the European Rapid Chess Championship in Warsaw in 2007, the Abu Dhabi Chess Festival and Al Saleh International Open in Yemen in 2009, the Orissa International GM Open in 2011, and the Mumbai event in 2012. He also finished second at the European Individual Chess Championship in 2000 and shared victory at the President's Cup in Baku in 2008. — — In terms of playing style and openings, Aleksandrov has employed a broad repertoire. As White he frequently used systems such as the Nimzo-Indian (various lines), King's Indian setups, and Slav defenses in response patterns, along with Queen’s Gambit and English variations. He has occasionally played flank openings, including lines with an early b4 (Sokolsky/Polish/Orangutan), though it does not appear as his absolute main choice in large databases. As Black he has shown comfort in the Queen’s Gambit Declined (including Ragozin), Nimzo-Indian, and various responses to 1.e4. He has defeated strong players, including a notable win over Alexander Morozevich. — — Aleksandrov has remained active in international opens into his 50s, accumulating significant experience across classical, rapid, and blitz formats. His career highlights a consistent ability to compete at a high level, with strong results in both individual and team events for Belarus over decades. — — Note created May 2026. (AI)

(=1.Nf3 Nf6 2.e3 g6 3.b4 Bg7 4.Bb2 0-0 5.Be2 d6 6.0-0) — — Lukasz Jarmula (born 10 November 1998 in Warsaw, Poland) is a Polish chess grandmaster, author, coach, and theoretician. His father, Ph.D. Adam Jarmula, introduced him to chess at a young age, and it quickly became his main passion and occupation. — — As a junior, Jarmula achieved significant success in Polish youth championships. He earned multiple medals in classical chess, including gold in the U16 category in Szczyrk in 2013 and gold in the U18 in Szklarska Poreba in 2016. He also secured silver medals in U16 (2014) and U18 (2015). In rapid chess, he won five silver medals, and in blitz he claimed several medals, including golds. Internationally, he represented Poland at five World Youth Chess Championships and two European Youth Chess Championships, with his best result being 4th place (shared 2nd) at the 2016 European Youth U18 in Prague. — — He received the FIDE International Master title in 2015 and the Grandmaster title in 2021. His peak FIDE rating reached 2512 in July 2018, with a current rating around 2412 as of 2026. He has worked with respected Polish coaches such as GM Bartosz Socko, GM Michal Olszewski, WGM Agnieszka Brustman, and IM Dominik Pedzich, who shaped his playing style. — — In team events, he contributed to winning the Polish Team Chess Championship in 2018 with WASKO Hetman GKS Katowice. He has participated in the Polish Chess Championship and regularly competes in strong open and round-robin tournaments. Notable individual highlights include 2nd place at the Czech Open in both 2018 (behind Sergei Movsesian) and 2020 (behind Lucas Van Foreest), each with a GM norm performance, and 4th place with a GM norm at the A. Margaryan Memorial in Yerevan in 2018. In 2024, he won two strong events: the 60th Akiba Rubinstein Festival Open A in Polanica Zdrσj with an impressive 8/9 score and 2696 performance rating, and the Rudar XIII GM round-robin in Pozarevac, Serbia. — — Jarmula maintains an active playing schedule in international tournaments while focusing on opening theory and coaching ambitious players worldwide. He has produced high-quality chess publications, including comprehensive repertoires such as "The Najdorf Bg5 Revisited" and "The Nimzo & Bogo-Indian Revisited," as well as material on the O'Kelly Sicilian in collaboration with IM Piotr Nguyen. These works emphasize deep theoretical research and practical ideas. — — Regarding openings, Jarmula is known more for solid, theoretically grounded systems rather than highly irregular ones like 1.b4 (the Polish/Sokolsky Opening), which does not appear as a primary choice in his repertoire. As White, he typically employs main lines such as 1.e4 or 1.d4. As Black, he favors flexible setups including the Nimzo-Indian and Bogo-Indian Defenses against 1.d4, and Sicilian variations (notably the O'Kelly) against 1.e4. His approach prioritizes harmony, flexibility, and deep preparation over surprise flanks. — — An interesting detail from his junior years includes a beautiful tactical combination in a game he won at age 14 (rated around 2050 at the time), which he still considers one of the most memorable in his career. His transition from promising junior to grandmaster reflects consistent theoretical work and strong performances in open tournaments. He continues to balance competitive play with authoring and coaching. — — Note created May 2026. (AI)

Melikyan,Gnel (2235) - Tokman,A (2395), Titled Tue (8), 2024. — — Gnel Melikian (full name: Gnel Melikian) was born on April 12, 1967, in Yerevan, Armenia, then part of the Soviet Union. He is an Armenian grandmaster and a long-time member of the Armenian chess scene both as a player and as a trainer. He earned the title of International Master in 1992 and was awarded the Grandmaster title in 2000 by FIDE. — — He developed within the strong Soviet chess system and later became part of Armenia’s highly successful national chess structure. Beyond his individual play, he is widely known for his coaching work, having trained top Armenian players including Levon Aronian during formative stages of their careers. — — In tournament play, Melikian achieved several solid international results rather than headline elite victories. He won or shared first place in a number of open tournaments and performed consistently in strong international fields during the 1990s and early 2000s. His peak FIDE rating was in the mid-2500s range, placing him comfortably at grandmaster level, though not among the very top elite. — — He represented Armenia in team competitions and contributed to the broader Armenian chess program, which became one of the strongest in the world in the 2000s, including successes at events like the Chess Olympiad, although Melikian himself is better known for his supporting and coaching role than for Olympiad medals as a player. — — As a coach, he has been particularly influential. He has worked with the Armenian national team setup and has been associated with the development of multiple grandmasters. His work emphasizes positional understanding, structured preparation, and disciplined calculation. — — Regarding his playing style, Melikian is generally described as a positional and strategic player rather than a purely tactical or speculative one. His games often feature solid opening preparation, careful piece placement, and gradual accumulation of small advantages. He is not typically associated with highly experimental or flamboyant systems. — — On opening choices, there is no strong evidence that 1.b4, known as the Sokolsky Opening, is a regular or defining part of his repertoire. His games show a preference for more classical openings. With White, he has most often employed 1.e4 and occasionally 1.d4. With Black, he has played a range of mainstream defenses typical of his era, focusing on reliability rather than surprise value. — — Overall, Gnel Melikian’s importance in chess lies less in individual tournament fame and more in his role as a respected grandmaster and influential coach within Armenian chess, contributing to one of the most successful national chess traditions of the modern era. — — Note created April 2026.

Corona Monraz,Ramiro (1965) - Jayasundara,P (1870), Titled Tue (6), 2025. (=1.b4 e5 2.Bb2 d6 3.e3 Nf6 4.Nf3 g6 5.Be2 Bg7 6.0-0 0-0) — — Ramiro Corona Monraz is a Mexican chess player born in 1968 (sometimes listed as 1969), with FIDE ID 5107717. He represents Mexico and maintains a FIDE standard rating around 1969 (peak historically near 2105). He has no formal FIDE title and is listed as inactive in standard ratings on his profile, though he remains active in online and rapid events. — — He participates regularly in online tournaments such as Titled Tuesday on Chess.com and other platforms, facing a range of opponents including titled players. His overall record in available databases shows a mix of results, with wins against peers and losses against significantly higher-rated opponents, consistent with an active club-level competitor. He has also played in correspondence events and over-the-board tournaments in Mexico, such as the Mexican Open. — — Corona Monraz strongly favors the Polish Opening (Sokolsky), 1.b4, often followed by Bb2, e3, and setups involving f4 or c4. He deploys it consistently even against stronger players, using it to steer games into unconventional positions early and avoid mainstream theory. Games frequently feature lines like 1.b4 e5 2.Bb2 or similar structures with early flank expansion and central control attempts. This choice aligns with his inclusion as a featured player on dedicated 1.b4 resources. — — His approach emphasizes offbeat, flank-oriented openings to take opponents out of preparation. He shows comfort with unbalanced positions, early pawn advances on the queenside, and tactical complications arising from non-standard setups. Play often involves kingside fianchettos for Black responses or direct central challenges. Performance indicates solid tactical awareness around the 2000 level, though results can vary against much stronger opposition. He demonstrates persistence in long games, as seen in multi-move encounters with complex middlegames. — — Interesting details include his recognition in the global community of 1.b4 enthusiasts, highlighted on Marek's 1.b4 World site in late 2025 as a dedicated practitioner from Mexico. He contributes to the broader network of players who keep this rare opening alive in competitive play. He has faced various international opponents in online events and remains an active figure in Mexican chess circles. — — Note created May 2026. (AI)

Olteanu,Adrian (1760) - Santos Latasa,J (2620), Grand Prix Bucharest (1), 2025. — — Adrian Olteanu is a Romanian chess player born in 2010. He holds no FIDE title and competes primarily in national and regional events in Romania, such as various Romania Grand Prix tournaments and rapid/blitz team competitions. — — His current FIDE ratings stand at approximately 1744 in standard, 1839 in rapid, and 1813 in blitz. He has participated in open tournaments like the Arad Open and Bucharest Grand Prix events, facing a range of opponents. His recorded database games are limited in number, with mixed results in the small sample available. — — Regarding openings, he has employed 1.b4 (the Sokolsky or Polish Opening) with White in documented games, often following up with Bb2, Nf3, and setups involving e3, c4, or d3 against responses like ...Nf6 and ...g6. As Black, he has faced various lines but shows no highly specialized repertoire in public records. This choice of 1.b4 stands out as an interesting preference for a young player, favoring flank development and unbalanced positions over more mainstream central openings. — — As a teenager active in the mid-2020s, Olteanu continues to gain experience in domestic competitions. Like many promising juniors, his career focuses on consistent tournament play to build rating and skill rather than major international titles so far. One detail from his games includes a win as Black against an opponent in a Sicilian setup, highlighting his ability to capitalize on opportunities in tactical positions. — — Note created May 2026.

He holds a peak FIDE rating of 2487 in classical chess, with rapid and blitz ratings around 2416-2420. He earned the IM title and showed rapid progress as a junior, securing the FIDE Master title at age 14. — — In his career, Levin has represented Israel in international youth events such as the World Youth Chess Championship and European Youth Chess Championship. He has competed successfully in Israeli team championships and open tournaments, often performing well against higher-rated opponents including grandmasters. Notable results include strong showings in the Israeli Open Championship and team events, with unbeaten or dominant runs in some domestic competitions. In 2022, as a teenager, he won a national title while remaining unbeaten ahead of several grandmasters. He achieved his final GM norm at the European Individual Chess Championship in Poland, positioning him close to the grandmaster title. — — Levin is known for an aggressive and tactical style that has helped him secure wins against strong players. He has participated in events like the Gambit GM Closed and various hybrid and over-the-board youth championships. His rapid rise places him among Israel's promising young talents alongside players like Ido Gorshtein. — — Preferred openings: With White, he frequently employs systems starting with 1.Nf3 or 1.d4, favoring setups such as the English Opening (especially lines like A13, A10), the Reti System (A06, A04), and Queen's Pawn Games including the London System or Torre Attack. He shows flexibility rather than strict mainline commitments. There is no strong evidence he regularly plays 1.b4 (the Sokolsky or Polish Opening) as a primary choice; it appears occasionally but not as a mainstay. With Black, he responds solidly to 1.e4 and 1.d4, often using Sicilian or various Indian defenses depending on the opponent. — — Interesting details include his ability to outperform expectations in team and open events, scoring notable victories against titled players while still in his mid-teens. His games often feature sharp tactical battles, and he has been part of Israel's rising chess scene, contributing to youth team successes.

He won the World Under-14 Championship in 1989 and achieved the Grandmaster title in 1992. — — His peak achievement came in 2005, when he won the FIDE World Chess Championship in San Luis, Argentina, dominating a field of eight top players to claim the world title. In 2006, he played a historic unification match against Classical World Champion Vladimir Kramnik, losing narrowly in a rapid playoff. Topalov reached the World Championship match again in 2010, where he challenged Viswanathan Anand but was defeated. — — He achieved the world number one spot on the FIDE rating list in April 2006 and held the top position for a total of 27 months during his career. His peak Elo rating reached 2813 in 2006, placing him among the highest-rated players in chess history. He also won numerous elite international tournaments, including Linares, Wijk aan Zee, and M-Tel Masters. — — Topalov is a highly aggressive, classical player. He does not use 1.b4 (Sokolsky/Silesian Opening) as a preferred or standard opening choice. — — Instead, his preferred choices with White are 1.e4 and 1.d4. With 1.e4, he frequently steers into the open lines of the Sicilian Defense or the sharpest main lines of the Ruy Lopez. With 1.d4, he regularly plays the Queen's Gambit, the Catalan, and main lines against the King's Indian Defense. — — With Black, Topalov is famous for using the Najdorf Variation of the Sicilian Defense to create complex, double-edged positions. Against 1.d4, he historically favored the Grόnfeld Defense and the Semi-Slav Defense. — — Topalov became well-known for an uncompromising, ultra-aggressive style of play, rarely agreeing to short, tactical draws. His manager and trainer for much of his peak career was Silvio Danailov. — — Topalov was a participant in Garry Kasparov's final professional tournament game at Linares in 2005, a game which Topalov won. He was also on the losing end of one of the most famous endgame moves in history, when Alexei Shirov played the stunning bishop sacrifice 47...Bh3 against him in 1998. — — Note created May 2026.

His father, Ph.D. Adam Jarmula, introduced him to chess at a young age, and it quickly became his main passion and occupation. — — As a junior, Jarmula achieved significant success in Polish youth championships. He earned multiple medals in classical chess, including gold in the U16 category in Szczyrk in 2013 and gold in the U18 in Szklarska Poreba in 2016. He also secured silver medals in U16 (2014) and U18 (2015). In rapid chess, he won five silver medals, and in blitz he claimed several medals, including golds. Internationally, he represented Poland at five World Youth Chess Championships and two European Youth Chess Championships, with his best result being 4th place (shared 2nd) at the 2016 European Youth U18 in Prague. — — He received the FIDE International Master title in 2015 and the Grandmaster title in 2021. His peak FIDE rating reached 2512 in July 2018, with a current rating around 2412 as of 2026. He has worked with respected Polish coaches such as GM Bartosz Socko, GM Michal Olszewski, WGM Agnieszka Brustman, and IM Dominik Pedzich, who shaped his playing style. — — In team events, he contributed to winning the Polish Team Chess Championship in 2018 with WASKO Hetman GKS Katowice. He has participated in the Polish Chess Championship and regularly competes in strong open and round-robin tournaments. Notable individual highlights include 2nd place at the Czech Open in both 2018 (behind Sergei Movsesian) and 2020 (behind Lucas Van Foreest), each with a GM norm performance, and 4th place with a GM norm at the A. Margaryan Memorial in Yerevan in 2018. In 2024, he won two strong events: the 60th Akiba Rubinstein Festival Open A in Polanica Zdrσj with an impressive 8/9 score and 2696 performance rating, and the Rudar XIII GM round-robin in Pozarevac, Serbia. — — Jarmula maintains an active playing schedule in international tournaments while focusing on opening theory and coaching ambitious players worldwide. He has produced high-quality chess publications, including comprehensive repertoires such as "The Najdorf Bg5 Revisited" and "The Nimzo & Bogo-Indian Revisited," as well as material on the O'Kelly Sicilian in collaboration with IM Piotr Nguyen. These works emphasize deep theoretical research and practical ideas. — — Regarding openings, Jarmula is known more for solid, theoretically grounded systems rather than highly irregular ones like 1.b4 (the Polish/Sokolsky Opening), which does not appear as a primary choice in his repertoire. As White, he typically employs main lines such as 1.e4 or 1.d4. As Black, he favors flexible setups including the Nimzo-Indian and Bogo-Indian Defenses against 1.d4, and Sicilian variations (notably the O'Kelly) against 1.e4. His approach prioritizes harmony, flexibility, and deep preparation over surprise flanks. — — An interesting detail from his junior years includes a beautiful tactical combination in a game he won at age 14 (rated around 2050 at the time), which he still considers one of the most memorable in his career. His transition from promising junior to grandmaster reflects consistent theoretical work and strong performances in open tournaments. He continues to balance competitive play with authoring and coaching. — — Note created May 2026. (AI)

His current standard FIDE rating stands at 2342, with a peak so far of 2365. He also has rapid and blitz ratings around 2255 and 2418 respectively. — — As a junior player he has achieved notable success in age-group competitions. In 2025 he won the Open U15 section of the FIDE World School Chess Championship with 8 points. He also secured gold in the U16 Open at the Asian Youth Chess Championships 2025, scoring an unbeaten 7.5 out of 9. — — Scheglov has competed in stronger open events such as the Aeroflot Open in 2026, facing grandmasters like Pavel Ponkratov and others while still in his mid-teens. On online platforms like Chess.com, under the handle Batko_2010, he maintains an active presence with a solid overall performance record in his recorded games. — — Regarding openings, available statistics show a preference for somewhat unconventional systems as White. He has played Bird's Opening (1.f4) frequently with good results in his database entries, alongside occasional flank setups such as 1.Nf3 followed by b3 or even 1.a3. As Black he responds to 1.d4 and 1.e4 with established defenses including King's Indian or Slav structures in many games. While 1.b4 (Sokolsky/Orangutan) appears in some irregular or experimental lines, it is not among his primary or most frequent choices based on public game collections. — — An interesting aspect of his style is the willingness to enter imbalanced, non-theoretical positions early, which suits his aggressive junior-level play and has contributed to wins against higher-rated opponents in youth events. At 16 he continues to progress rapidly through strong performances in both classical and faster time controls. — — Note created May 2026. (AI)

He maintains rapid and blitz ratings in the low 2300s. — — Dauner competes regularly in open tournaments across Europe, including the Reykjavik Open, Grenke Chess Open, Benidorm Chess Open, Baden-Baden Faschingsopen, and German championships. He has faced top players in online events such as Titled Tuesdays on Chess.com, where opponents included grandmasters like Daniil Dubov, Levon Aronian, Ian Nepomniachtchi, and Kirill Alekseenko. — — Notable results include a strong performance in the Reykjavik Open 2024, where he scored 6.5 points and placed in the junior category prizes. He has secured wins against higher-rated players, such as a notable victory over grandmaster Pavel Eljanov (rated around 2680 at the time). In team and club events, he contributes points for German sides, including in cup matches and league play. — — Regarding openings, Dauner employs a varied repertoire. As White, he often starts with 1.d4 or 1.e4, showing flexibility in systems like the London System or more classical approaches. There is no strong evidence of heavy reliance on 1.b4 (Sokolsky/Orangutan Opening) as a primary weapon, though he experiments with flank and unconventional lines at times. As Black, he frequently uses solid or counterattacking setups such as the Scandinavian Defense, Owen's Defense, and various Indian systems. — — His database games (hundreds recorded across platforms) reflect an active style suited to open tournaments, with a mix of tactical sharpness and positional play. He participates in both over-the-board and online rapid/blitz events, maintaining consistent activity into 2025-2026. Interesting detail: despite his young age, he has already accumulated experience against elite grandmasters in both classical and faster time controls, showcasing rapid development as a competitive FM in the German chess scene. — — Note created May 2026.

He holds the title of International Master, awarded in 2019. His current FIDE classical rating stands at 2461 as of May 2026, with a peak rating of 2490 reached in January 2025. — — He began playing chess at age five in 2007, encouraged by his father. His early successes include winning the West Bengal State under-7 title in 2009, the under-9 in 2011, and both the state and national under-13 titles in 2015. He claimed the West Bengal State Open in 2017. — — In 2018, during his first European trip on the Catalan Circuit, he earned two IM norms in consecutive tournaments (Barbera del Valles and Sant Marti) and crossed 2400 in live rating. He secured his final IM norm at the Delhi Open in early 2019, progressing from untitled to IM in about six months. — — Notable later achievements include winning the MPL 50th National Junior Championship in 2022. In August 2024, he tied for first at the 61st Indian National Championship with 9/11 but placed third on tiebreaks. He has repeatedly won or performed strongly in rating opens, including three consecutive victories at the Late Bharatbai Halkude Memorial Chess Festival (with a perfect 9/9 score in June 2025). — — In January 2024, as an IM rated around 2446, he defeated GM Nigel Short with 1.b3 in the Bangalore International Open, winning in 27 moves after capitalizing on an error.

He participated in the FIDE World Cup 2025, losing in the first round to Georg Meier. — — Regarding openings, he has employed flexible and sometimes unconventional systems with White. He notably used 1.b3 against Short to minimize preparation. Chess.com data shows frequent use of the Catalan Opening, Trompowsky Attack, and various Reti/English setups like 1.Nf3 followed by b3 systems or 1.a3 in some games. He has experience with both 1.d4 and 1.e4 at different stages. — — Neelash has represented India in various events and continues to compete actively in open tournaments and team championships while maintaining a strong record in domestic and international rating events.

His current FIDE classical rating stands at 2657, with a peak of 2703 in March 2020, when he reached world number 35 and crossed the 2700 barrier. — — Career highlights and achievements include winning the Spanish championship eight times across various age groups and formats. He secured bronze at the 2012 European Youth U16 Championship and silver at the 2013 World Youth U18 Championship. In 2014, he took silver at the European Individual Championship, which qualified him for the FIDE World Cup, and he won the Spanish Blitz Championship that year, finishing ahead of Francisco Vallejo Pons. — — Other notable results feature winning the 2016 Magistral d'Escacs Ciutat de Barcelona on tiebreak over Jan-Krzysztof Duda, placing second at the 2017 Tradewise Gibraltar Masters (after leading much of the event and defeating players like Veselin Topalov and Boris Gelfand), and tying for third to eleventh at the 2019 European Individual Championship. In January 2020, he won the Tata Steel Challengers, qualifying for the Masters group the following year. He has represented Spain at two Chess Olympiads and won the 2025 Spanish Championship with 8/9, dominating a field with seven grandmasters. — — He has participated in strong events such as the FIDE Grand Swiss, World Cup, and various invitationals, with career earnings around $170,000. A strong rapid and blitz player, he has also competed in the Champions Chess Tour. — — Preferred openings: With White, he most commonly plays the Reti System, English Opening, and Nimzo-Larsen Attack variations, along with some Queen's Pawn systems. With Black, he frequently employs the Ruy Lopez, Giuoco Piano (Italian Game), and responses to Queen's Pawn openings. He does not notably favor 1.b4 (the Sokolsky or Orangutan Opening) as a main weapon; it appears rarely if at all in his repertoire, which leans toward solid, flexible positional setups rather than flank surprises. — — Interesting details include his victory over Magnus Carlsen in at least one classical game and consistent performances against top players. Known as "El Niρo" in some circles, he maintains a professional yet approachable style, often delivering strong results in open tournaments and national events while balancing competitive play with occasional coaching or content contributions. His peak form in 2019-2020 showcased him as one of Spain's leading grandmasters alongside Vallejo Pons. — — Note created May 2026. (AI)

Her mother introduced her to chess at age seven, alongside painting and music, to develop her intellectual and creative talents. She largely self-taught many skills but received coaching in Kharkiv and later Kramatorsk. By age 15 she had already won the Ukrainian under-20 girls championship. — — She earned the woman grandmaster title in 2003 and the international master title in 2007. In 2012 she gained the full grandmaster title after her world championship success. Her peak classical rating reached 2502 in 2007. — — In team events she contributed significantly to Ukrainian successes. She was part of the gold-medal winning team at the 2006 Turin Women's Chess Olympiad, remaining undefeated. Ukraine took silver in 2008 and additional medals in later years, including gold again at the 2022 Chennai Olympiad where she also earned an individual silver on board three. She helped secure team bronze at the 2007 Women's World Team Championship and claimed individual gold on her board at the 2007 European Team Championship. — — Her individual highlights include winning the Ukrainian women's championship in 2005. In 2016 she became European women's champion in Mamaia on tiebreak. She won the 2020 Women's Speed Chess Championship on Chess.com in a close final. Additional victories came in events such as the 2022 Tata Steel India Women's Rapid and the European women's rapid title in 2024. — — Ushenina captured the women's world championship in Khanty-Mansiysk in 2012 by defeating Antoaneta Stefanova in the final tiebreak, becoming the 14th titleholder. She held the crown until losing a 2013 match to Hou Yifan. During her title run she produced strong performances, including a notable win over Peter Svidler in the 2013 FIDE World Cup where she overcame a substantial rating gap in one game. — — As for openings, she nearly always starts with 1.d4 as White, favoring Queen's Pawn systems. As Black she commonly replies to 1.e4 with the Sicilian Defense. There is no notable record of her employing 1.b4 (the Orangutan or Polish Opening) as a preferred or frequent choice; it does not appear in descriptions of her repertoire. — — She remains active in league play, streaming, and coaching, maintaining a rating around the 2400s in recent years while continuing to compete at high levels. Her career combines classical strength with notable speed chess achievements. — — Note created May 2026. (AI)

(=1.b4 A05: Reti Opening: 1 Nf3 Nf6 1...Nf6 2.Bb2 g6 3.e3 Bg7 4.Nf3 0-0 5.Be2 d6 6.d4) — — Breno Barbosa de Siqueira Carneiro is a Brazilian chess player born on October 17, 1983. He earned the title of FIDE Master (FM) from the International Chess Federation, marking him as a high-level competitive player within the global and Brazilian chess communities. — — Throughout his career, Carneiro has been an active participant in the Brazilian chess circuit. He has competed in numerous national championships and international open tournaments. His competitive efforts earned him a peak FIDE rating in the 2300s. He is recognized for his ability to compete against International Masters and Grandmasters, often using his specialized opening knowledge to bridge the gap in theoretical preparation. — — The most defining characteristic of Carneiro's chess career is his expertise in the Sokolsky Opening, which is characterized by the initial move 1.b4. This opening is also known as the Orangutan or the Polish Opening. While many top-level players view 1.b4 as a secondary or surprise weapon, Carneiro adopted it as a primary part of his repertoire. He spent years analyzing the nuances of this flank opening, looking for ways to create imbalances that traditional openings like 1.e4 or 1.d4 do not typically produce. — — Carneiro is known for a creative and provocative playing style. By employing 1.b4, he often bypasses the extensive opening preparation of his opponents, forcing them into original positions early in the game. His style relies on a deep understanding of the positional structures arising from 1.b4, such as the pressure on the long a1-h8 diagonal and the specific pawn structures in the center. He excels in positions where he can utilize his superior knowledge of obscure lines to outmaneuver opponents who are more accustomed to mainstream theory. — — The legacy of Breno Carneiro is cemented by his work as a chess author. In 2014, he published a book titled The Sokolsky Opening: 1. b4 through Everyman Chess. This book is considered a significant modern contribution to chess literature, offering a comprehensive and objective look at an opening that had previously lacked detailed modern coverage. His work provides players with a roadmap for using 1.b4 at the club and professional levels, ensuring his influence on the game continues through the students and enthusiasts of the Sokolsky Opening. — — Note created March 2026.

He holds the title of International Master, awarded in 2026, after earning the FIDE Master title in 2020. His peak standard rating reached around 2400, with a current rating near 2399. He represents Spain and competes actively in both over-the-board and online events. — — He grew up in Spain and progressed steadily through the junior ranks before establishing himself among the country's stronger young players. By his early twenties he regularly faced grandmasters in open tournaments and team competitions, particularly in Catalan and Spanish leagues. — — In his chess career he has participated in numerous Spanish championships and international opens. Notable performances include a strong showing in the Spanish Individual Championship 2025, where he finished in a high position with solid points. He has also competed successfully in events such as the Barcelona Holy Week IM tournament and various closed and open internationals in Spain. He plays regularly in team events like the Lliga Catalana and Spanish league divisions. — — His achievements center on consistent improvement and earning IM norms through competitive results against titled players. He has recorded wins against strong opponents and maintained a rating that places him among Spain's active international masters. Online he maintains an active presence on platforms like Chess.com under the handle gueraumasague. — — Regarding preferred openings, database statistics show he frequently employs Reti setups with White, such as 1.Nf3 followed by systems leading to A06 and A04 codes. He also plays the English Opening and other flank systems. There is no prominent evidence of a heavy preference for 1.b4 (the Sokolsky or Orangutan Opening) in his main games; his repertoire appears more aligned with flexible, hypermodern approaches rather than irregular flank gambits. With Black he faces a range of replies including Sicilian and other semi-open defenses. — — An interesting detail is his relatively rapid rise to the IM title in his early twenties while balancing domestic league play and international opens, reflecting dedication typical of Spain's active chess scene in Catalonia. He continues to compete at a level where he can challenge higher-rated grandmasters in individual events. — — Note created May 2026. (AI)

He holds the FIDE Candidate Master title and has represented his country in various national and international events. He is also a FIDE National Arbiter since 2022 and a FIDE Instructor. — — He maintains a standard rating around 2055, with rapid around 1970-2000 and blitz in the 2060 range, having peaked near or above 2115 in earlier years. He is based in Santiago de los Caballeros and remains an active competitor in Dominican tournaments as well as online events like Chess.com Titled Tuesdays. — — In his chess career, Feliz Dotel has participated in multiple Dominican national championships and pre-national qualifiers, consistently placing in the mid-to-upper field among the country's active players. He has faced both local titled players and international opponents in open and team events, with notable games against stronger masters where he has secured occasional upsets or solid draws. He also serves in organizational roles, such as deputy chief arbiter in regional tournaments. — — His playing style includes a preference for offbeat and flank openings. He has employed 1.b4 (the Sokolsky or Polish Opening) with some regularity, fitting the query's suggestion, which leads to unbalanced positions that reward creative piece play and queenside space grabs rather than mainline theoretical battles. This choice aligns with his approach of steering games into less explored territory where preparation edges and practical chances matter. He also uses systems like the Reti in certain lines. — — Interesting details include his dual role as player and instructor/arbiter, contributing to chess development in the Dominican Republic through education initiatives. At around age 40, he stays competitive in a scene featuring younger talents, often delivering resilient performances in faster time controls where his blitz rating shines. His online handle Dewarfd appears on platforms like Chess.com and Lichess, where he engages in regular titled events. — — Note created May 2026. (AI)

He holds the FM title and has competed actively in tournaments across Europe and beyond, representing Turkiye. His peak FIDE classical rating reached 2369, with a current rating around 2326-2333 as of recent updates. He also maintains rapid and blitz ratings near 2180. — — In his career, Sari has participated in various open tournaments, including events like the Rilton Cup, Amsterdam Chess Open, Tata Steel weekend tournaments, and others in the Netherlands and elsewhere. He has secured wins against higher-rated players, such as a notable victory over Aaditya Dhingra rated 2495, and has shown solid performance with around 40% wins, 43% losses, and 16% draws across hundreds of recorded games. He frequently plays in team or league competitions in Europe. — — His playing style features active piece play and he has demonstrated the ability to upset stronger opponents in open events. As a Turkish player active in the 2020s, he contributes to the federation's presence in international opens without major individual world or European titles noted in standard profiles. — — Regarding preferred openings, available data from game databases highlights more mainstream choices rather than a heavy reliance on 1.b4. On Chess.com, his most played lines as White include responses in the Sicilian (such as Alapin variations) and other e4 systems, while as Black he engages with defenses like the King's Indian, Slav, and various Indian setups. He shows versatility but no prominent specialization in the Sokolsky/Orangutan (1.b4) as a primary weapon in public statistics, though many club-level and FM players experiment with offbeat openings occasionally. — — Interesting detail: Sari has recorded strong tournament results in events with mixed international fields, occasionally finishing in the top 10 of opens and delivering quick wins with precise tactical execution against titled players. His consistent activity keeps him as a competitive FM in the mid-2300s range. — — Note created May 2026. (AI)

He holds no FIDE title and maintains a classical Elo rating around 1966, with rapid and blitz ratings in the low 2050s. His peak classical rating reached 2245. — — He has participated in various Polish and international events, including European Rapid and Blitz Championships in 2017, as well as senior team competitions like the FIDE World Senior Team Chess Championship 50+ in 2024. In database samples of around 190 games, he scores roughly 38% wins, 32% losses, and 30% draws. He has faced stronger opponents in these events and recorded wins against higher-rated players on occasion. — — Slabek plays regularly in Polish tournaments and team events. Notable results include wins against players like Bartosz Sleczka (multiple times) and occasional upsets or competitive games against titled players. He continues active play into his 60s, particularly in senior categories. — — Regarding openings, he employs a range of systems. As White, he has used 1.b4 (Sokolsky/Polish/Orangutan Opening) in some games, fitting an offbeat and flank-oriented style that can surprise opponents and lead to unbalanced positions early. He also plays more standard lines such as various 1.d4 or 1.e4 setups depending on the opponent. As Black, he responds flexibly, often meeting 1.e4 with Sicilian or other semi-open defenses and 1.d4 with Indian or Queen's Gambit structures. His games sometimes feature sharp tactical battles or prolonged endgames. — — An interesting aspect of his career is his longevity in competitive chess, remaining active in senior events while balancing play against much younger or higher-rated competition. He has a solid record in rapid and blitz formats relative to his classical strength. — — Note created May 2026. (AI)

He holds the FIDE Candidate Master title and has represented his country in various national and international events. He is also a FIDE National Arbiter since 2022 and a FIDE Instructor. — — He maintains a standard rating around 2055, with rapid around 1970-2000 and blitz in the 2060 range, having peaked near or above 2115 in earlier years. He is based in Santiago de los Caballeros and remains an active competitor in Dominican tournaments as well as online events like Chess.com Titled Tuesdays. — — In his chess career, Feliz Dotel has participated in multiple Dominican national championships and pre-national qualifiers, consistently placing in the mid-to-upper field among the country's active players. He has faced both local titled players and international opponents in open and team events, with notable games against stronger masters where he has secured occasional upsets or solid draws. He also serves in organizational roles, such as deputy chief arbiter in regional tournaments. — — His playing style includes a preference for offbeat and flank openings. He has employed 1.b4 (the Sokolsky or Polish Opening) with some regularity, fitting the query's suggestion, which leads to unbalanced positions that reward creative piece play and queenside space grabs rather than mainline theoretical battles. This choice aligns with his approach of steering games into less explored territory where preparation edges and practical chances matter. He also uses systems like the Reti in certain lines. — — Interesting details include his dual role as player and instructor/arbiter, contributing to chess development in the Dominican Republic through education initiatives. At around age 40, he stays competitive in a scene featuring younger talents, often delivering resilient performances in faster time controls where his blitz rating shines. His online handle Dewarfd appears on platforms like Chess.com and Lichess, where he engages in regular titled events. — — Note created May 2026. (AI)

He earned the international master title in 2014 and the grandmaster title in 2015, becoming the 41st grandmaster from India. His peak FIDE rating reached 2695 in March 2024, with a world ranking as high as number 40 in May 2024. As of March 2026 his FIDE rating stands at 2608, placing him around number 17 in India. — — Narayanan began playing chess as a child after watching his mother compete in a tournament. He received early training from former Kerala state champion P. Sreekumar and later from international master Varugeese Koshy, as well as grandmasters including Praveen Thipsay, Alexander Goloshchapov, and Avetik Grigoryan. He also attended a training camp with grandmaster Yevgeny Vladimirov in 2011. His family made significant sacrifices to support his chess career, with his father leaving his job to accompany him to tournaments. — — In junior chess Narayanan won the Kerala state under-9 championship in 2007 and secured multiple state titles in under-11, under-13, sub-junior, and junior categories. At the national level he won gold in the National Junior Championship in 2014. Internationally he claimed gold in the Commonwealth under-16 championship in 2012, silver in the Asian Junior Championship in 2015 and 2016, gold in the Asian Junior Blitz Championship in 2016, and bronze in the World Junior Championship in 2016 held in Odisha. He represented India on first board at the under-16 Chess Olympiad, contributing to a bronze medal for the team. — — Among his notable senior achievements are victory in the Ellobregat Open in Spain in 2019 after a playoff, a win in the Chess.com Titled Tuesday online tournament in 2019 against a strong field including Hikaru Nakamura and Wesley So, and a bronze medal in the Qatar Masters Open in 2023. He has competed in the FIDE World Cup and achieved a silver medal with the Alkaloid team in the European Club Cup in 2024. In 2017 he defeated then-reigning world blitz champion Sergey Karjakin in the Aeroflot Blitz tournament. Narayanan has also participated in club competitions and open tournaments across Europe and Asia, earning prize money estimated around 70,000 US dollars in his career. — — His playing style is described as balanced, combining solid preparation with efforts to improve weaknesses through analysis of his own games. He has shown strong handling of certain middlegame structures, such as those arising from the exchange Ruy Lopez. As black he has frequently faced the Sicilian Defense, Ruy Lopez, Nimzo-Indian Defense, and Queen's Gambit Declined. As white his games include various queen's pawn openings and other systems, though no single dominant repertoire stands out as unconventional or centered on 1.b4. He dedicates several hours daily to training, mixing study, online play, and review of classical games for deeper understanding beyond pure engine evaluation. — — Narayanan has been recognized for sportsmanship, such as declining a walkover against a grandmaster at age 11 to play the game fairly. He has contributed to chess in Kerala and India as part of the generation of grandmasters emerging from the country. He maintains a professional approach focused on reaching higher ratings and contributing to team events like the Olympiad while balancing academic excellence, having scored perfectly in his higher secondary examinations. — — Note created March 2026.

Born in 1998, he has been an active competitor and instructor in the Colorado chess scene for years. — — He earned the NM title and achieved a USCF rating peak above 2210, including a notable 4-0 performance that pushed him to that level around 2022. His FIDE standard rating has hovered around 1912 (with a rapid rating near 1957), consistent with his domestic over-the-board success where ratings often run higher. He has won or shared prizes in events such as the Wyoming Open (where he took first in 2023), Denver Chess Club tournaments (including the 2025 DCC Premier Championship), and various local opens and quick championships. He has also recorded strong online performances, notably defeating IM Levy Rozman in a Titled Tuesday blitz event. — — Herman works as a chess instructor and participates regularly in Colorado clubs and tournaments, contributing to the local scene through teaching and play. He remains active into 2025-2026, with recent tournament appearances and club events. — — Regarding openings, he employs a varied repertoire rather than a narrow set of favorites. As White, he has used systems including the Reti and has played the Polish/Sokolsky Opening (1.b4), sometimes followed by early development like Bb2. One documented game opened 1.Nf3 Nf6 2.b4. As Black, he has faced and employed defenses such as the Dragon Sicilian, Philidor, Scandinavian, and Old Indian in tournament play. His games show flexibility, with both tactical and positional approaches depending on the opponent and event. — — Interesting aspects of his play include strong tactical vision that leads to kingside attacks and upsets against higher-rated or titled players. He maintains involvement in both over-the-board and online chess, balancing competitive results with community teaching. His mother, Shirley, has also played in some of the same events, adding a family dimension to his local tournament participation. — — Note created May 2026. (AI)

He holds the FIDE Candidate Master title and has represented his country in various national and international events. He is also a FIDE National Arbiter since 2022 and a FIDE Instructor. — — He maintains a standard rating around 2055, with rapid around 1970-2000 and blitz in the 2060 range, having peaked near or above 2115 in earlier years. He is based in Santiago de los Caballeros and remains an active competitor in Dominican tournaments as well as online events like Chess.com Titled Tuesdays. — — In his chess career, Feliz Dotel has participated in multiple Dominican national championships and pre-national qualifiers, consistently placing in the mid-to-upper field among the country's active players. He has faced both local titled players and international opponents in open and team events, with notable games against stronger masters where he has secured occasional upsets or solid draws. He also serves in organizational roles, such as deputy chief arbiter in regional tournaments. — — His playing style includes a preference for offbeat and flank openings. He has employed 1.b4 (the Sokolsky or Polish Opening) with some regularity, fitting the query's suggestion, which leads to unbalanced positions that reward creative piece play and queenside space grabs rather than mainline theoretical battles. This choice aligns with his approach of steering games into less explored territory where preparation edges and practical chances matter. He also uses systems like the Reti in certain lines. — — Interesting details include his dual role as player and instructor/arbiter, contributing to chess development in the Dominican Republic through education initiatives. At around age 40, he stays competitive in a scene featuring younger talents, often delivering resilient performances in faster time controls where his blitz rating shines. His online handle Dewarfd appears on platforms like Chess.com and Lichess, where he engages in regular titled events. — — Note created May 2026. (AI)

He holds the FIDE Candidate Master title and has represented his country in various national and international events. He is also a FIDE National Arbiter since 2022 and a FIDE Instructor. — — He maintains a standard rating around 2055, with rapid around 1970-2000 and blitz in the 2060 range, having peaked near or above 2115 in earlier years. He is based in Santiago de los Caballeros and remains an active competitor in Dominican tournaments as well as online events like Chess.com Titled Tuesdays. — — In his chess career, Feliz Dotel has participated in multiple Dominican national championships and pre-national qualifiers, consistently placing in the mid-to-upper field among the country's active players. He has faced both local titled players and international opponents in open and team events, with notable games against stronger masters where he has secured occasional upsets or solid draws. He also serves in organizational roles, such as deputy chief arbiter in regional tournaments. — — His playing style includes a preference for offbeat and flank openings. He has employed 1.b4 (the Sokolsky or Polish Opening) with some regularity, fitting the query's suggestion, which leads to unbalanced positions that reward creative piece play and queenside space grabs rather than mainline theoretical battles. This choice aligns with his approach of steering games into less explored territory where preparation edges and practical chances matter. He also uses systems like the Reti in certain lines. — — Interesting details include his dual role as player and instructor/arbiter, contributing to chess development in the Dominican Republic through education initiatives. At around age 40, he stays competitive in a scene featuring younger talents, often delivering resilient performances in faster time controls where his blitz rating shines. His online handle Dewarfd appears on platforms like Chess.com and Lichess, where he engages in regular titled events. — — Note created May 2026. (AI)

He holds the **FIDE Master** title and represents Chile in competitions. His current FIDE ratings are approximately 2059 in standard, 2066 in rapid, and 1972 in blitz. — — He has participated in numerous national and international events over more than two decades, including multiple editions of the Chilean National Absolute Championship, where he has faced top domestic players. He also competes regularly in online titled tournaments and open events such as the Chess Boss Chess Tour series and various opens in Chile and abroad. As a FIDE-licensed trainer with over 20 years of experience, he works as a coach and promotes chess in Chile. — — Cuevas Araya maintains an active online presence, notably on Chess.com as waltereador, where he plays frequent games against strong opponents, sometimes scoring notable wins or draws against higher-rated players in rapid and blitz formats. His overall database results show a mix of competitive performances typical for a solid FM-level player in open and national-level events. — — Regarding preferred openings, he employs a variety of systems. He has been seen using the London System with White. With 1.b4 (the Sokolsky or Orangutan Opening), it aligns with occasional use of flank openings, though it is not his absolute main line. As White he often starts with 1.e4 or 1.d4 depending on the opponent. As Black he responds flexibly to 1.e4 (including Sicilian lines) and 1.d4. He demonstrates practical, fighting chess rather than a narrow theoretical repertoire. — — An interesting detail is his longevity in the game: he has competed in events spanning from at least the early 2010s through 2026, balancing tournament play with coaching and federation-related activities, such as involvement in the Chilean Chess Federation environment. He occasionally pulls off tactical upsets or solid defensive performances against grandmasters and international masters in open tournaments. — — Note created May 2026. (AI)
