Damir Studen (matein28): A Bullet Board General
Damir Studen, known online as matein28, is a National Master whose username promises a checkmate in 28 moves. The numbers suggest he usually delivers long before the clock forces him to make good on that promise. He favors bullet chess above all other time controls, and his account reads like a highlight reel of fast, fearless play.
Career Snapshot
From his early bullet battles in late 2010 to his recent surge in 2026, Damir has steadily climbed the online ladder. His bullet peak is 2858 (2026-09-09), a number that places him in elite company among online speed chess players. His longest winning streak reached 43 games, and he has built a reputation for punishing hesitation with relentless activity.
Playing Style
Damir plays with a mix of patience and explosive timing. His endgame frequency sits near 70.6 percent, meaning he rarely lets a game end before the pieces thin out. His average winning game lasts about 68 half moves, while his losses stretch even longer, which suggests he fights hard in every phase of the game.
- White win rate: 79.6 percent
- Black win rate: 78.3 percent
- Comeback rate: 79.4 percent
- One-sided loss rate: under 2 percent
- Best time of day to face him: probably never, but especially not at 10:00
Signature Openings
Damir has a clear opening identity. As Black he regularly embraces the Scandinavian Defense, turning the early queen sortie into a weapon rather than a liability. As White he often heads for the London Poisoned Pawn Variation, a sharp line that rewards players who know their theory. He also enjoys the Amazon Attack and the Australian Defense, and his results with these setups are consistently strong across bullet, blitz, rapid, and daily chess.
Rivalries and Habits
No player has faced Damir more often than moo6o6, with 416 meetings between the two. Damir owns the series with 331 wins, 44 losses, and 41 draws. That rivalry alone shows his durability, because grinding out hundreds of games against the same opponent requires both mental stamina and a very fast mouse.
Damir also checks early and often. He is the first player to give check in about 62.6 percent of his games, and when he lands that first check he wins 83.4 percent of the time. His favorite checking piece is the queen, which fits a player who likes to keep the pressure on from move one.
