Meet IM tuzibaba
tuzibaba is a FIDE International Master with a username that sounds like a favorite uncle calling everyone to dinner and a playing style like a metronome that has discovered espresso. Blitz is the day job, Rapid is the happy place, and endgames are where opponents go to slowly realize what is happening to them.
From 800 to Sniper in One Month
In April 2020, a brand new blitz account appeared rated 800. By the end of that same month, after 407 games, it had blasted past 2200 and touched 2374. Bullet ratings followed the same trajectory, leaping from 957 to 1920 in one lunar cycle. Either this was the single greatest improvement project in chess history or the most elaborate practical joke ever played on the rating pool. History does not record which, only the wreckage.
The 1.e4 Loyalist
As White, tuzibaba has been described as allergic to the d-pawn. In 2025, out of 4,495 rated games, exactly 4,452 opened 1.e4. The most frequent guest is the Caro-Kann Defense, faced 982 times with a 56% score, followed by the Sicilian Defense: Najdorf Variation and the Modern, which gets beaten over 62% of the time. As Black, the calling card is the Petrov's Defense, played 741 times with results of almost religious symmetry: 347 wins, 347 losses. Perfectly balanced, as all things should be.
The Endgame Anaconda
Games against tuzibaba do not end, they surrender. Roughly 78% of all games reach an endgame, the average win takes 75 moves, and the early resignation rate is a stubborn 1.19%. Drop a piece against this player and you have not blundered, you have simply started the difficult part: the win rate after losing material is 51.85%, and the comeback rate sits at an absurd 89%. The tilt factor is a comatose 11, and the longest winning streak ran 25 games.
- Win rate after sacrificing your own good mood: still over 50%
- Checks delivered with the king, purely out of confidence: 117
- Longest losing streak: 11 games, apparently during a total solar eclipse
Schedule of a Nocturnal Predator
The statistics are clear about one thing: tuzibaba should never be trusted before noon. The win rate peaks at 65.6% around 1 AM, stays lethal at 2 AM, and craters to 43.2% at 8 AM. The officially listed best time to play is 01:00, which means breakfast games are the closest thing opponents get to a fair fight.
Rapid, the Nearly Perfect Record
Rapid is where the champagne lives. The record reads 15 wins, 1 loss and 1 draw, with a peak of 2300, a scoreline so clean it could legally appear in advertising. The Rapid menu features rare delicacies like the Barnes Defense and the Australian Defense, both consumed without complaint. Bullet is no refuge either, with a 2300 peak and a Scandinavian flavored ambush kit that has eaten plenty of clock-blind victims.
Rivalries and One Nemesis
No opponent has faced tuzibaba more than Chesstrueno, with 43 encounters and a knife edge 22-20-1 scoreline, the definition of a feud that will never truly be settled. Meanwhile Sergey Kornilov actually holds a winning 15-12 edge, making them the closest thing tuzibaba has to an arch nemesis. Then there is ski-ba-bop-ba-dop-bop, who has played 29 games against tuzibaba, presumably just so the match history would look incredible.
The Legacy
International Master tuzibaba, in summary: opens 1.e4 with religious devotion, checks overwhelmingly with the queen 13,760 times and counting, grinds 75-move endgames until opponents apologize to their own pawns, and does the very best work after midnight. Peak blitz strength of 2686 (2026-10-05), a Rapid record that borders on fiction, and a career defined by one simple truth: it is never over with this player until it is over.
