Siziku: Rook-Check Connoisseur of Bullet Chess
Every online chess community has its specialists, and Siziku is the bullet chess one. A devoted fan of clock-fueled chaos, Siziku holds a bullet peak of 2913 (2026-08-22) alongside a blitz peak of 2914 (2025-07-07), a suspiciously symmetrical pair of numbers proving it is impossible to pick a favorite speed. Over 2,700 rated games analyzed, thousands of rook checks delivered, and a combined blitz-and-bullet win column that never once involved playing slow.
The Great January Ascent
Siziku's rating history opens like an action movie: a January 2023 blitz rating of 1341, followed by 362 games in a single month, and a finish above 2700 before February could voice an opinion. After some quiet stretches, the bullet chess debut arrived in July 2025, and the climb resumed in earnest. The chart below tells the rest of the story.
Repertoire: 1.d4 and the Scandinavian Faith
As White, Siziku plays exactly one first move. In 2026 the tally read 491 games of 1.d4 against two lonely experiments with 1.d3, apparently done on a dare. From there, the Amazon Attack with an early Bf4 is the main weapon, usually steering into Siberian Attack lines, with Torre Attack setups and Döry Defense structures rounding out the menu. As Black, the Scandinavian Defense is practically a religion: 455 blitz games of 1.e4 d5, with the queen landing on d5 before the mouse cools. Bullet opponents who dare the Nimzo-Larsen Attack should note that Siziku scores 56% against it.
Style File
- Plays an endgame in over 82% of games. Sprinting is for other people.
- First capture usually arrives around move 7. There is an opening to play first.
- Comes back from worse positions at a 90% clip, which is convenient, because the clock creates plenty of practice opportunities.
- Has flagged opponents 254 times while being flagged 761 times. The clock giveth and the clock taketh away.
- Checks with rooks more than any other piece, over 2,400 rook checks and counting.
- Almost never resigns early, tilts about as often as a Tuesday, and pairs a 12-game win streak with a 13-game losing streak in perfect balance.
- The 5 a.m. win rate sits at 71%. The 4 a.m. sample is best left unexamined. Play Siziku before breakfast at your own risk.
Frenemies of the Fast Board
No bullet career is complete without rivalries. javier has absorbed 14 losses in just 17 meetings, while mch stands at a flawless 7-0-1. On the other side of the ledger, Kevin Bordi owns a 1-5-2 edge and deserves thanks for keeping Siziku humble. And when the format stretches to rapid, the Siberian Attack turns a menacing 8-0-1, a gentle reminder that with more time on the clock, the d4 machine only gets scarier.
