Meet krzychu225: Bullet Chess Night Owl and Rapid Grinder
If online chess ever builds a hall of fame for people who refuse to sleep, krzychu225 gets a statue. This is a player who has logged thousands of bullet chess games, clawed up from a Rapid rating of 804 to triple that, and once touched 2801 (2025-05-15) in bullet. The preferred time control is Rapid, but make no mistake: the bullet arena is where this legend was forged, one flagged opponent at a time.
The Rapid Redemption Arc
In March 2021, the Rapid rating hit rock bottom at 804. Many players would have deleted the app and taken up checkers. krzychu225 instead started grinding. By December 2022 the climb had passed 2100, and by July 2026 it peaked at 2248 (2026-07-12). The Rapid ledger now reads 236 wins, 86 losses and 67 draws, close to a 3:1 ratio, which is what happens when an endgame specialist realizes slower clocks simply mean more time to watch opponents squirm.
7,500 Bullet Games and a Streak for the Ages
The bullet record stands at 4,029 wins, 3,121 losses and 437 draws. That is more bullet games than some people have had hot dinners. The journey began in 2015 with wild swings between 1341 and 1999, and ended up at 2801 (2025-05-15) in May 2025 after one of the most stubborn climbs in online chess. Along the way came a 39-game winning streak and, earlier still, a 2016 daily chess run of 37 wins before a single loss. Here is the decade in one picture:
Style: The Marathon Grind
This chess is less lightning raid, more endless siege. The numbers describe a professional pleasantry-avoider:
- Endgame frequency of 80.72%: nearly every game sinks into an endgame, which is exactly where he wants you.
- Early resignation rate of 2.04%: resigning is not in the repertoire. Dead-lost positions are simply invitations to be annoying.
- Comeback rate of 85.64%: drop a piece on him and start sweating. He still wins over half his games after losing material.
- One-sided loss rate of 3.36%: when he loses, you genuinely earned it.
- Average first capture on move 8: he does not grab, he waits for you to self-destruct.
- Average winning game lasts over 82 moves: a slow-motion mugging.
There is also the small matter of 1,925 wins on time versus 1,239 by checkmate. The clock is officially his favorite attacking piece.
The Offbeat Opening Arsenal
Forget mainlines. As Black, the Czech Defense is basically a lifestyle, played 472 times in bullet alone. The Amar Gambit has been rolled out 446 times at a 55% win rate, which is frankly more than it deserves. The Nimzo-Larsen Attack hits 70% in blitz, and the Australian Defense, Amazon Attack: Siberian Attack and Hungarian Opening: Wiedenhagen-Beta Gambit round out a repertoire engineered to drag opponents into strange waters, then let the endgame do the drowning. Somewhere in the collection sits a top-secret Colle line called the Rhamphorhynchus Variation, named after a pterodactyl, presumably because facing it feels like being pecked by something prehistoric.
Rivals, Nemeses and One Very Tough Roach
Every grinder keeps a gallery of repeat victims and repeat abusers:
- hannibal4: 45 games and counting, with a 26-16-3 edge. A decade-long war of attrition, and krzychu225 is ahead.
- THO_Chess36: 9 wins against 13 losses. The textbook nemesis. Some people collect stamps.
- LadyCockroach: another sting at 10-13, proving insect-themed opponents bite back.
- FlirezaAiroujza: 19-4. The designated prey. Everyone needs one.
The 11pm Monster
The time-of-day data reveals a nocturnal predator: at 23:00 the win rate is a jaw-dropping 72.41%, the best hour by a country mile. Around 4am it collapses to 33%, at which point the monster turns back into a pumpkin. The tilt factor sits at a zen-like 12, so bad beats roll off like rain, and casual games run about 36 points hotter than rated ones. The most dangerous krzychu225, in other words, is the one with nothing to prove.
Legacy in Progress
Even blitz has climbed to a 2674 (2026-05-13) peak. Ten years, thousands of games, a resignation rate so low that resignation itself has filed a complaint, and a chess biography still being written at 82 moves per win. The advice is simple: never challenge krzychu225 at 11pm. Seriously. Wait until 4am.
