Datris Robinson (Opcheck): The Bullet Chess Marathoner
Datris Robinson, better known online as Opcheck, is a bullet chess institution. Between 2011 and 2026, they played nearly 62,000 rated bullet games, plus thousands of blitz, rapid, and daily games. The numbers make it clear: bullet is Opcheck's home, and they have the stamina to prove it.
The Long Climb
Robinson entered the online chess scene in September 2011 with a bullet rating just above 1500. For years, Opcheck bounced around the 1400s and 1600s, collecting losses and lessons in equal measure. Then the floodgates opened. In 2021 and 2022, monthly game counts shot into the thousands, and the rating finally followed. By the summer of 2026, Opcheck reached a 2212 (2026-07-20) of 2212, while blitz peaked near 2178 and rapid crossed the 2000 mark.
The journey from 1500 to 2200 was a grind in the truest sense. Opcheck has won 29,702 bullet games, lost 29,461, and drawn 2,830. That is an almost perfectly balanced ledger of blood, sweat, and increment-free heartbreak.
Signature Openings and Endgame Grit
When Opcheck is White, the Amazon Attack is the weapon of choice: more than 10,000 bullet games with a 53.5% win rate. The Australian Defense also appears in the thousands, while as Black, Robinson leans heavily on the Caro-Kann Defense. They have faced the Caro-Kann Exchange Variation over 4,000 times, so nothing about that solid structure is a surprise. In blitz, the French Defense became a quiet secret weapon with a 68% score.
Style-wise, Opcheck is a fighter to the final move. Endgames appear in about 81% of their games, and their comeback rate sits near 84%. Even after losing a piece, they still win 45% of the time. The first capture usually lands around move six, which makes for scrappy, hand-to-hand bullet chess.
Rivalries and Rematches
No name appears more often in Opcheck's history than fullcirclechess, who won 129 of their 172 bullet meetings. But Robinson has a victory lap against misterdimos, holding a 71 to 43 edge. spinningbullets also shows up in 61 games, which is less a rivalry and more a shared commitment to never backing down.
