Kacper Drozdowski (Kacparov)
Kacper Drozdowski, better known online as Kacparov, is an International Master who treats the bullet clock like a dance partner and the opening book like a treasure chest. His online footprint points to one clear truth: bullet is his natural habitat. His bullet peak is 3161 (2026-08-15), his blitz peak is 3095 (2026-03-24), and his rapid peak is 2787 (2026-09-21). If you match with him late at night, you are probably in for a very fast lesson.
From daily grind to bullet chaos
His online journey begins in 2009 with daily games, and by 2010 he is already exploring bullet. The real explosion happens in January 2022, when he plays more than 1,600 bullet games in a single month. That is not a heavy schedule. That is a love story told in premoves.
Opening repertoire
Kacper is a creature of habit. He plays e4 with overwhelming frequency, and his opening identity is built around the Sicilian Defense. He also leans on the Caro-Kann Defense, plus the Giuoco Piano and the occasional Amazon Attack, which sounds more like a superhero move than a chess line.
In rapid play, his scores with the Sicilian Kan and Closed Sicilian are devastating, including a win rate above 90 percent with the Closed Sicilian as Black. If he drifts into Najdorf territory, expect fire. Here is a taste:
.Pressure and comebacks
Kacper is not easy to discourage. He wins nearly 79 percent of his games after falling behind, and his win rate after losing a piece is still around 58 percent. He reaches the endgame in about 75 percent of games, proving that even bullet lovers know how to grind when needed.
At his best he once rattled off 50 consecutive wins. The data also hides a wild 207 game losing streak, which suggests that even a bullet prince occasionally loses the plot after too many 1am sessions.
Rivalries and the night shift
His most played opponent list reads like an online chess hall of fame. He has faced Hikaru Nakamura 96 times, taking 12 wins and 13 draws. Those games are probably short, sharp, and very loud.
He is statistically strongest around 1am, and Sunday and Thursday are his best days. Maybe the board is quieter then, or maybe he simply runs on chess and stubbornness.
