Petar Kovač (Pezyr): The Blitz Marathoner
From Improbable Beginnings to FIDE Master
Petar Kovač, known online as Pezyr, is a FIDE Master whose online chess journey began in 2017 with modest ratings and a whole lot of curiosity. His early blitz form was unassuming, but by the summer of 2020 he found another gear, winning 85 of 117 games in a single month and launching himself toward the 2500 level.
A Blitz Specialist Built for Volume
Blitz is clearly home. Petar has played thousands of rapid-fire games, with a peak blitz rating of 2888 (2026-09-08) reached in June 2025. His rating graph tells the story of a player who never stops grinding:
. Along the way he has collected a longest winning streak of 17 games and a comeback rate above 86 percent, which means very few leads are safe against him.Repertoire and Playing Style
Petar's opening tastes are adventurous. As White he leans on the Caro-Kann Defense and the Sicilian Defense family, while as Black he regularly reaches for the Scandinavian Defense and the Nimzo-Larsen Attack. His games tend to be long and tense, with an average decisive game stretching past 80 moves, and he is not afraid to defend lost positions. His endgame frequency is high, and his early resignation rate is low.
Rivalries and Resilience
No biography of Pezyr would be complete without his recurring battles against Lovro Novosel. The two have faced each other 30 times in blitz, with Petar holding a narrow 15-12 edge. Another frequent foe, PracticeMakesOK, has given him more trouble, winning 13 of their 19 meetings. These rivalries have helped shape his fighting spirit.
