Roy Vagman: The Bullet-Fast International Master Known as Moncler08
Who Is Roy Vagman?
Roy Vagman, known to his online opponents as Moncler08, is a FIDE International Master whose entire online presence screams speed chess. His preferred battlefield is bullet, the format where every second counts and intuition replaces calculation. With a bullet peak of 2790 (2026-08-04) and a blitz peak of 2850 (2025-05-27), Vagman has proven he can hang with the very best in the fastest formats. He is also undefeated in his small rapid sample, showing that his skills are not limited to flagging alone.
Opening Repertoire and Style
Vagman wins with chaos. His opening choices are a mix of respected defenses and borderline trolling. As White he loves to unleash the Amar Gambit, an offbeat line that punishes unprepared opponents, and his near 71% bullet win rate in that opening is a warning to anyone who thinks they can memorize their way past him. As Black he is comfortable in the Scandinavian Defense and the Caro-Kann Defense, though his Caro results are curiously human, which adds a little humility to an otherwise terrifying profile. He also experiments with the Colle Rhamphorhynchus Variation, the Barnes Defense, and the Hungarian Opening, making preparation against him a nightmare.
Online Rivalries
No online grinder exists in a vacuum, and Vagman's history is full of familiar names. His most frequent opponent is Itay Sitbon, who has faced him 116 times; Vagman leads that series with 57 wins. He has a stronger edge over Ilay Zakin, winning 60 of their 106 meetings, and he absolutely owns amaslidan, with 46 wins in 71 games. These rivalries give his profile a living, breathing energy, like a small online chess town where everyone knows the local bullet boss.
Bullet Chess Brilliance
Look at Vagman's bullet rating graph and you will see a player who grinds relentlessly. From 2024 through 2026 he pushed his bullet rating above 2700 multiple times, peaking at 2790 (2026-08-04). He plays his best chess early in the morning, with a win rate near 80% at 07:00, and Thursdays are his lucky day. The chart below tracks his bullet journey, showing a player who never stays down for long.
Comebacks and Combativeness
Perhaps the scariest thing about Roy Vagman is not his opening tricks but his refusal to die. He has an 88.21% comeback rate, meaning when he is behind, he still wins most of the time. Even after losing a piece, he wins nearly half his games, a nightmare statistic for anyone who thinks a material advantage is safe. His longest winning streak reached 16 games, and his longest losing streak, 9 games, feels almost like a vacation for his opponents. He almost never resigns early and he flags opponents with glee, collecting more timeout wins than checkmate wins. For Moncler08, the game truly ends when the clock hits zero.
