TonyMatonny: Antonín Sadil, Czech Bullet Chess Machine
Antonín Sadil, known to opponents and victims alike as TonyMatonny, is a Czech chess player who treats bullet chess less like a hobby and more like a cardio program. Since first appearing online in 2019, he has played nearly 17,000 analyzed games, the overwhelming majority at bullet speed, climbing from a sub-1000 newcomer into a genuine bullet heavyweight with a peak rating of 2347 (2026-06-21).
The Autumn of the Relentless Mouse
Every grinder has a breakthrough, and Antonín's came in late 2022. In a single season he rocketed from the 1000s to above 2000, and November 2022 alone featured 2,135 rated bullet games, roughly 71 per day, every day, with zero rest days and apparently zero wrist complaints. Since then he has cruised in the 2000 to 2200 zone, touching 2347 in June 2026.
Repertoire: Solid, Sneaky, Solid Again
With the black pieces, Antonín is a devoted Caro-Kann Defense player, logging well over 1,400 bullet games in the solid old bruiser. The Scandinavian Defense is his trusty backup, and quietly his most productive defense by win rate. When the mood strikes, he unleashes the cheeky Amar Gambit across more than 600 games, because at bullet speed, confusion counts as a strategy.
With White, his headline weapon is the Scotch Game, far and away his most profitable opening in bullet, blitz and rapid alike:
How He Wins: The Flag, Usually
- More than 3,200 wins on time, comfortably outpacing his checkmate wins. Certified clock assassin.
- Over 2,700 wins by resignation, because opponents glance at the position, then at the clock, then sigh.
- An 86.81 percent comeback rate, and wins even after dropping material in nearly half of those games.
- Endgames appear in about 79 percent of his games. He grinds long, he grinds slow, and he does it all in sixty seconds.
- An early resignation rate of just 1.15 percent. TonyMatonny does not do quit.
- 349 stalemate draws on record, the politest possible way to ruin someone's evening.
Friends, Victims, and One True Nemesis
No bullet regular survives alone, and Antonín's most-played opponents read like a Czech chess group chat:
- neumimulohy: a flawless 19-0 record. Somewhere out there, a rematch remains pending.
- kubastepanik: 17 wins against a single loss, practically a paid tutorial series.
- little_teriii: 21 meetings, 13 draws. The eternal coin flip that keeps landing on its edge.
- filip_kohout: 36 games and counting, his most frequent dance partner, though the ledger leans the wrong way.
- ivanzemlicka: 18 losses against just 6 wins. Every hero needs a villain, and this one is doing heroic work.
Quirks and Habits
Antonín's win rate peaks at 3:00 in the morning, which is either a superpower or a crime against sleep schedules. Saturday is his best day of the week, Tuesday is best avoided entirely. He checks more often with rooks than any other piece and lands the first check in more than half of his games, a diplomatic way of saying he applies pressure early. His tilt factor sits at a zen-like 10, and while his longest winning streak reached 13 games, his 10-game losing streak has clearly left no visible scars.
Antonín Sadil by the Numbers
- Over 6,600 bullet wins and more than 1,300 bullet draws, with a peak blitz rating of 2100 for good measure.
- Average winning game length: 76 moves. Even his victories are marathons.
- White win rate: 49.6 percent. Black win rate: 45.7 percent. Balance is everything.
- Longest winning streak: 13 games. Bullet hyenas hunt in streaks.
The verdict is simple. If you face TonyMatonny at 3:00 AM with your clock bleeding, you have two options: resign with dignity, or embrace the flag. Statistically, you will embrace the flag.
