Meet Quentin Moore

Quentin Moore, better known to the chess internet as Qcorn, is a National Master with a serious addiction to the one minute clock. He has spent more than a decade turning opening prep into speed chess chaos, and his board presence is equal parts calculation and caffeine.

The Bullet Brain

When Qcorn sits down for bullet, he is in his element. He has played more bullet games than most people have played total games, hitting a peak bullet rating of 2601 (2026-08-01). His blitz rating is just as scary, reaching 2725 (2026-03-20) while he was clearly having the time of his life.

Qcorn's rock solid results are built on a wall of experience. He is the kind of player who will flag you, then beat you in the rematch, then beat you again in the third game for good measure.

Opening Repertoire

Qcorn keeps things practical and sharp. He loves the Sicilian Defense, especially the Taimanov and Alapin setups, and he has a soft spot for the Amazon Attack and the Caro-Kann Defense Exchange. As White he mostly pounds out d4, and as Black he is happy to drag opponents into complicated middlegames.

Rivalries

Qcorn's longest running feud is with Tom Haverford, who has faced Qcorn over 400 times and lost most of them. He also owns the head to head against rdwiz, where he holds 52 wins against only 2 losses, and sirlongcastle has felt the Qcorn effect too.

If you see Qcorn in the queue, bring a snack. It is going to be a long series.

By the Numbers

  • Longest winning streak: 42 games
  • Comeback rate: 85 percent
  • Best hour to face him: never, but especially 11:00 AM
  • Casual games: where he truly lets his hair down

The Comeback Kid

Qcorn once won 42 games in a row. That is not a typo. Even when things go wrong, his comeback rate sits around 85 percent, which means he is never really out of a game.

His tilt factor is a perfect 10, but that only makes the comeback sweeter. The best time to catch him is 11:00 AM, when his win rate spikes and opponents should probably just stay in bed.
