Christopher Guzman: FIDE Master and Blitz Endurance Artist
Christopher Guzman, known online as ajedrezsinlimites, is a FIDE Master with a fitting motto: chess without limits. His blitz career is a testament to that idea, with more than 10,000 games, a peak blitz rating of 2948 (2026-06-05), and enough stamina to exhaust an entire server.
The Blitz Marathoner
Between 2020 and 2026, Guzman's blitz rating climbed from solid club level to a stratospheric peak in June 2026. The journey was rarely smooth, but it was always entertaining.
His recorded blitz record stands at 5,065 wins, 4,597 losses, and 1,014 draws. That is roughly 10,700 games of pure persistence, and it explains why his longest winning streak is 11 games while his longest losing streak is 16. He simply refuses to step away from the board.
Playing Style: The Grinder
Guzman plays the long game. Around 88% of his battles reach an endgame, and his average winning contest stretches to nearly 90 moves. He is also incredibly hard to put away: his comeback rate sits at 90.71%, and he still wins 46% of the time even after losing a piece. Opponents hoping for an early resignation are usually disappointed.
Interestingly, his best hour is 7:00 AM, when his win rate climbs above 55%. He might be a night terror, but he is a morning monster.
- Endgame frequency: 88%

Opening Repertoire
With the white pieces, Guzman almost always reaches for 1.e4. His most trusted friends there are the Caro-Kann Defense: Exchange Variation and the Sicilian Defense: Najdorf Variation. With black, he is a devoted Caro-Kann Defense player, having faced that setup over 1,600 times, and he uses the Tiviakov line of the Queen's Indian Defense when White stays away from open games.
Rivalries and Resilience
No bio is complete without rivals. Guzman's most frequent opponent is Sherif Khater, with 86 meetings and a 43 to 33 edge in his favor. He has also traded blows with Ezra Chambers (48 games) and Vladimir Bilic (30 games).
Then there is Baadur Jobava, the opponent who owns him: 39 games, 37 losses, 1 draw, and just 1 win. Every marathoner has a wall, and hers is shaped like a rook.
Despite the painful stretches and a tilt factor of 16, Guzman keeps queueing up. His comeback rate is the real headline, and his willingness to sit through 90 move losses is, frankly, admirable. Chess without limits, indeed.
