The Bullet Soldier of the Colle System
Christopher Knox, known online as ColleOfDuty, is a National Master who treats bullet chess like a military campaign. While others enjoy slow strategic lunches, Knox is busy grinding out rapid-fire games with 1.d4 and a smile. His bullet rating reached a peak of 2924 (2025-12-22) in late December 2025, a climb that shows up beautifully in
.Trench Warfare in the Colle
His username is a love letter to the Colle System, a queen's pawn setup he plays with the discipline of a drill sergeant. In his favorite bullet line, Colle: 3...e6 4.Bd3 c5, he has played 100 games and won 70 of them. As White, he almost never touches e4; the opening data shows an overwhelming obsession with d4. He also enjoys the Döry Defense and the Sicilian Defense when he needs to counterpunch as Black. A look at his opening report card would make any coach proud:
.Rivals and Redemption
No bullet soldier fights alone. Knox has a long-running rivalry with Drabmajor2011, whom he has faced 27 times and beaten 23 times. If drabmajor2011 is his favorite target, his kryptonite is Aman Hambleton, who leads their series 15 to 3. Even so, Knox owns a 19-game winning streak and an 86% comeback rate, so writing him off is a mistake. He even wins more than 60% of the time after losing a piece, which is less a blunder habit and more advanced psychological warfare.
The Numbers Behind the Name
Knox plays his best chess at 13:00 according to his performance data, and his matches are not quick handshakes. His wins average over 80 moves, meaning opponents have plenty of time to feel the pressure. He delivers the first check in 56% of his games and prefers decisive results over draws.
