Player Profile
Teimur Toktomushev, known online as DeArron_Fox, is a FIDE International Master with a serious appetite for online chess. If his username hints at speed, his statistics confirm it. He has played tens of thousands of bullet and blitz games, turned the Sicilian Defense into a personal laboratory, and once rattled off 32 consecutive wins before the chess gods reminded him that losses exist.
Although his profile suggests a fondness for Rapid, his real home is the fast lane. He has pushed both Blitz and Bullet to extraordinary heights, reaching 3068 (2026-08-27) in bullet and 2895 (2026-08-03) in blitz. For a player who started around 1500, that climb is the kind of thing that makes opening books nervous.
Career Trajectory
The chart above shows his rise from a promising amateur to a player who regularly trades blows with titled opposition. He wins about 66 percent of games against lower rated players, and even when facing stronger opposition he keeps fighting. His comeback rate is 86.56 percent, meaning he has a habit of rescuing lost positions like a chess version of a heist movie.
His longest winning streak is 32 games, and his longest losing streak is 11, which he likely prefers not to discuss. His data suggests his best time to play is around 1:00 AM. Night owls approve.
Style and Openings
DeArron_Fox is not shy about taking the game into unusual territory. In bullet, his most played opening is the Amar Gambit, followed by the Modern Defense and the Nimzo-Larsen Attack. He scores impressively in sharp lines, including a perfect 100 percent record in Rapid with the Sicilian Defense Taimanov Variation, American Attack.
His London System Poisoned Pawn play is also effective, and he holds a healthy plus score against the Slav Defense. For a sense of how his opening choices translate into results,
