Jerzy Slaby: The International Master Who Never Leaves the Bullet Queue
Overview
Jerzy Slaby, known online as JSlaby, is a FIDE International Master with a very specific specialty: bullet chess. While his surname might translate to "weak" in Polish, his rating history disagrees. Since 2019, Slaby has played more than 58,000 rated bullet games, climbing to a peak bullet rating of 2863 (2026-01-01) and a peak blitz rating of 2895 (2026-06-11). He treats the one-minute clock as a suggestion and the premove as an art form.
A Bullet Career for the Ages
Slaby's online journey began quietly in June 2014 with a single bullet game and a rating of 1364. He then vanished, returning in June 2019 with 173 games in one month. By July 2019, he was playing 1,354 games in a single month, roughly 45 games per day. The rating graph shows a player who simply does not stop.
His win rate sits just under 50%, which sounds ordinary until you consider the volume. He has won 27,908 bullet games and lost 28,040, with 2,462 draws. He has delivered over 9,900 checkmates while being checkmated fewer than 1,900 times. His real enemy is the clock: he has lost 18,166 games on timeout. That is the bullet lifestyle.
Familiar Foes
With so many games, Slaby has developed rivalries. His most frequent opponent is Anselm Wagner, who has beaten him 106 times in 191 meetings. Oleg Gamayev has also gotten the better of him, 67 wins to 58. Never_walk_alone leads their series 70 to 58, and Leo Bispo is ahead 64 to 57. Against Khoa Bui, however, Slaby holds a winning record of 58 to 45, proving that even in bullet chaos there is order. For a taste of the madness, check out this bullet clash.
Opening Repertoire
Slaby is a creature of habit. His most played bullet opening is the Caro-Kann Defense with over 3,000 games. He also loves the Czech Defense, the Sicilian Defense: Closed, and the Modern defense. As White, he frequently employs the Nimzo-Larsen Attack and, somewhat incredibly, has played the Amar Gambit more than 2,700 times. In blitz, he favors the Amazon Attack: Siberian Attack, a line most players would not touch with a ten-foot knight. His best result comes from the Czech Defense in blitz, where he wins 55.48% of the time.
Playing Style and Quirks
Slaby rarely resigns, with an early resignation rate barely above 1%. He has an 86.21% comeback rate and wins 45.44% of games even after losing a piece. His longest winning streak is 24 games, and his longest losing streak is 16, suggesting he tilts hard but recovers harder. His best time of day to play is exactly midnight, and his tilt factor of 16 means the 3 a.m. bullet sessions are probably legendary. In rapid, he has a perfect record: two games, two wins.
