zuginfinito: The Infinite Grinder
An Infinite Appetite for Chess
The name zuginfinito promises an endless supply of zugzwang, and the player behind it delivers. Since March 2020, this Blitz-loving online chess grinder has turned the clock into a playground, piling up thousands of games while climbing from a modest 1371 to a monster 2500 rating. The preferred time control is clearly Blitz, and the volume is staggering.
zuginfinito does not just play games, they collect them. There are more than 3,800 Blitz games and more than 3,100 Bullet games in the archive, plus a little Rapid and Daily chess for variety. The longest winning streak was 21 straight games, and even a 10 game losing streak could not stop the grind.
A Five Year Marathon
The Blitz rating history is not a straight line, but it is a stubborn one. In March 2020, zuginfinito started around 1371. By the end of that year, the rating had kissed 2200. There were dips, including a quieter 2023, but the recovery was always coming. On October 27, 2025, the infinite grind finally reached 2500 (2025-10-27).
Opening Repertoire: d4, d4, and More d4
zuginfinito is a system player at heart. With White, the first move is almost always 1.d4, often heading into the Colle System or the London System. The London System's Poisoned Pawn Variation has been especially friendly, producing a win rate near 67% across hundreds of games. With Black, the French Defense is the safety blanket, and the Exchange and Advance variations have both been highly profitable.
Even weird openings become part of the story. The Döry Defense, the Australian Defense, and the Amazon Attack's Siberian Attack have all shown up, and zuginfinito rarely panics. They simply outlast the opponent in an endgame.
Rivals and Repeat Customers
No great grinder is complete without a cast of rivals. The most frequent visitor to zuginfinito's board is Jéssica Trindade Hubner, with 429 meetings. zuginfinito owns that rivalry, winning 335 games to 83 losses and 11 draws. The mirror image appears against Vitor Alexandre Koren: in 151 games, vitorkoren has 85 wins while zuginfinito has 56. Even an infinite grind has a shadow.
Resilience, Habits, and Oddities
The numbers paint a picture of a tough, stubborn competitor. Decisive games tend to be long, often crossing 76 moves, and zuginfinito is heavily involved in endgames rather than quick kills. The early resignation rate is only 1.72%, and even after losing a piece, the player wins 58.43% of the time. The comeback rate sits at 86.2%.
zuginfinito also feasts when favored, winning 77.6% against lower rated opponents, but only 30% against higher rated ones. Somehow, that makes the 2500 peak even more impressive.
