Michael Kleinman
Michael Kleinman, better known online as michaelk123, is a FIDE International Master whose online career is defined by relentless volume and a taste for the unconventional. He first appeared on the platform in 2011 at around 1400 blitz and climbed all the way to a stunning 2716 peak, proving that consistent play can turn a promising amateur into a genuine online powerhouse.
Blitz Dominance
Blitz is where Michael Kleinman truly lives. With 1876 wins, 1780 losses and 303 draws, he has played thousands of fast games while keeping a healthy plus score throughout. His peak blitz rating of 2716 (2026-09-07) arrived in September 2026, and the chart below shows how steady that rise has been.
Bullet is his other playground. He touched 2704 in bullet during September 2020, and his rapid game peaked at 2603 in 2019. Whether the clock gives him one minute or ten, Michael finds a way to create winning chances.
Repertoire and Playing Style
Michael's repertoire is practical but fearless. As Black in blitz, the Caro-Kann Defense is his most trusted weapon, appearing in over 400 games. As White, he frequently reaches the Sicilian Defense Chekhover Variation and the Ruy Lopez Closed. In bullet, he has played the Amar Gambit more than 300 times, which is either a bold artistic choice or a very committed running gag. Probably both.
His games are not rushed blunders. He reaches the endgame 83.52% of the time, and his average win lasts about 77 moves. The first capture of the game typically happens around move 7, which suggests he develops his pieces before starting the fireworks. Here is a classic Caro-Kann structure he knows well:
Rivalries
A career with thousands of games is built on rivalries. Michael's most frequent foe is MasterLeif, who has faced him 101 times and leads the series 57 wins to 31. Against Leo Bispo the tables turn, as Michael has 51 wins in their 91 meetings. Other regular opponents include capatl, cstevens1, aliencowboy, devinprod, pultineviciuspaulius, gamayevoleg, stellarchess, and birdmaster3000.
Resilience and Mindset
What separates Michael from the average online grinder is his refusal to fold. His comeback rate is 86.47%, meaning he almost always finds a way back into the game. Even after losing a piece he still wins 45.63% of the time. His longest winning streak is 16 games, and his longest losing streak is also 16 games, which suggests he takes risks and accepts the consequences. His best results come at 8 a.m. with a 57.36% win rate, so the early bird really does get the rating points.
