arnacman: The FIDE Master Who Turned Blitz Into a Marathon
From 1388 to 2661, One Game at a Time
Meet arnacman, a FIDE Master whose true home is the blitz board. The profile may list Daily chess as the preferred time control, but the facts are stubborn: more than 21,000 rated blitz games, a bullet peak of 2579, and a blitz rating trajectory that looks like a stock tip that never stopped working.
It started in October 2014 with a modest 1388 rating and 110 games in a single month. From there the climb was relentless. The rise from 2100 in 2014 to 2400 in 2018 and beyond is on full display in the career chart
. The summit came in August 2026, when arnacman touched 2661 (2026-08-09).There were setbacks, of course. A 16 game winning streak is balanced by an 11 game losing streak, which means arnacman has experienced both euphoria and humility. The comeback rate of 87.65% suggests humility never lasted long.
Rivalries Built Over Thousands of Games
After 21,000 blitz games, the same faces appear again and again. arnacman leads the all time series against ofer zemertov with 34 wins in 53 games, and against jlindner with 24 wins in 35 games. But every hero has a nemesis: Antonio Vitor holds a 25 to 19 edge in their 47 game rivalry, which is probably why arnacman keeps coming back for more.
A Style Built on Refusing to Lose
The statistics paint a picture of a player who treats every lost position as a suggestion. Wins last about 77 moves, losses last about 89 moves, and endgames show up in 86% of games. When arnacman drops a piece, the game is far from over: they still win 50.49% of the time, a number that should terrify anyone who plays for a cheap tactic.
- White win rate: 54.84%
- Black win rate: 50.38%
- 62.51% win rate against lower rated opposition
- 29.84% win rate against higher rated players, because they keep taking the hardest fights
The Opening Laboratory
As White, arnacman is almost religiously devoted to 1.e4. The only brief affair with 1.d4 happened in 2023, and by 2024 the relationship was over. The main event is the Sicilian Defense, which appears in more than 1,700 of arnacman's games, including over 1,600 battles in the razor sharp Najdorf Variation. Opponents have also tried the tricky Blackburne Shilling Gambit more than 800 times and found arnacman ready with a 54.5% score as White. Against the solid Caro-Kann Defense, arnacman enjoys a 56.6% win rate. The
chart shows a repertoire as wide as the game count is deep.The Midnight Special
