Khosro Al: The Bullet Machine
Khosro Al, known online as bigboy417, is a volume-heavy online chess warrior. With more than 89,000 rated games, he has spent most of his chess life in bullet, firing off moves at lightning speed and climbing from a 1030 bullet start in December 2020 to 2177 (2024-11-14) in November 2024. His all-time Blitz ceiling is even higher, touching 2384, but bullet is clearly his comfort zone.
Repertoire and Style
Khosro is a creature of habit. As Black, he reaches for the Australian Defense again and again, with thousands of games in that opening across bullet and blitz. As White, he prefers 1.d4 and often transforms the game into Queen's Gambit Declined structures. His games are not quick sprints; the average decisive battle lasts around 70 moves, and his endgame frequency sits above 80 percent.
His queen is his favorite checking piece, and he is generally the first player to deliver a check about half the time. He also shows remarkable resilience: he comes back in roughly 82 percent of losing positions and still wins about 40 percent of games after dropping a piece.
Rivalries and Mad Streaks
No story about bigboy417 would be complete without dantejo22. The two have played nearly 2,000 games against each other, and dantejo22 has gotten the better of the rivalry by a wide margin. Khosro keeps coming back anyway, which says a lot about his stamina. Against cyrusbzp, however, he holds a healthy winning record and is far more comfortable.
His longest winning streak is 16, while his longest losing streak is 58. That kind of swing takes true dedication. His best time of day is 12:00, and he performs noticeably better in rated games than in casual ones, so when the points are on the line, he locks in.
