Meet Jack Mizzi

Jack Mizzi, who battles online as ATM622, is a FIDE Candidate Master with a serious love for fast chess. While he has played every time control, his ratings tell a clear story: he is a bullet specialist at heart. He has climbed to bullet peaks beyond 3000 and shattered the 2800 mark in blitz, proving he can think at warp speed and still find winning ideas.

The Bullet Grinder

Jack's online footprint is enormous. He has played tens of thousands of bullet games, with over 26,000 wins in that format alone. His bullet journey includes massive monthly climbs, wild swings, and a willingness to keep clicking even after tough streaks. His longest winning streak reached 57 games, while his longest losing streak hit 292, a stretch that would make most players log off. He kept going, and the results speak for themselves.

His strength in the fastest format is also visible in his opening choices. Rather than sticking to safe main lines, Jack embraces creative and offbeat setups. He has played the Amar Gambit thousands of times, and he regularly punishes opponents with the Blackburne Shilling Gambit. He also handles classical replies like the Caro-Kann Defense and the Scandinavian Defense with a practical, aggressive touch.

Signature Style

Jack is not a player who waits around. His stats show a bias toward active piece play, early captures, and a preference for reaching the endgame. He wins more often when he delivers the first check, and his comeback rate sits near 77 percent, meaning he rarely gives up when behind. His best time to play appears to be around 13:00, when his win rate peaks.

  • Comeback rate: 76.95 percent
  • Most common checking piece: Queen
  • Preferred time control: Bullet

Familiar Rivals

No online grinder thrives without rivals. Jack has faced toastbread_1 more than 1,000 times, building a dominant head-to-head record against toastbread_1. He has also crossed swords hundreds of times with aleksandr04082011, Aleksandr04082011, and greekalphamale, with greekalphamale. These marathon rivalries show his consistency and appetite for rematches.

Candidate Master, Online Warrior

Jack Mizzi is more than a title. He is a volume shooter, a bullet enthusiast, and a player who turns unusual openings into dangerous weapons. His journey from modest club-level ratings to Candidate Master strength is a reminder that online chess can be a real path to improvement, especially when you bring energy, creativity, and a very fast mouse.
