Juan Saenz (gunsberg): The Blitz Grinder
Juan Saenz plays chess under the handle gunsberg, and the handle fits. This is a player who treats the clock as a challenge rather than a warning, having logged more than 43,000 analyzed games, split almost perfectly between blitz and bullet. The blitz record alone reads 11,208 wins, 9,174 losses and 1,547 draws. Nobody accumulates a ledger like that by accident. It takes years, stubbornness, and a willingness to press "new game" one more time at midnight.
The high-water marks are serious. Blitz peaked at 2486 (2019-03-05) in March 2019, and bullet climbed to 2413 (2023-09-20) in September 2023, which is the sort of bullet rating that makes opponents double-check the pairing. Blitz is the preferred home, and the long rating chart tells the story of a player who spent 2017 and 2020 bouncing violently between 2,100 and 2,400 and always climbed back.
The Eternal 1.d4 Devotee
If you want to know what gunsberg will play on move one, the answer is 1.d4, and it is not close. In 2015 the split was 3,579 games with d4 against 180 with e4. In 2016 it was 3,924 to 72. Even in 2026, with thousands of games on the clock, d4 remains the default. Opponents who prepare wild e4 theory are preparing for a convention that is not happening.
The opening menu is delightfully eccentric. The Döry Defense appears in roughly 1,600 blitz games, a line that confuses people who assumed a quiet d4 complex. The Australian Defense shows up nearly as often, alongside the Modern Defense and gambit fare like the Hungarian Opening's Wiedenhagen-Beta Gambit. With the black pieces, the Scandinavian Defense is the workhorse, appearing in over 2,000 bullet games, while the Benoni Defense Benoni Gambit Accepted accounts for more than 1,000 blitz battles and the Sicilian Defense Classical supplies another 780. None of this is mainstream preparation. All of it is deeply personal.
A Style Built for Long Fights
Here is the surprise: a blitz specialist who reaches the endgame in about 87 percent of games and needs an average of 81 moves to win. The average first capture does not land until move 6.86, which means the pieces come off late and the position gets squeezed rather than blitzed. Early resignations are rare, sitting under half a percent, so opponents can expect a full shift.
The resilience numbers are the fun part. Gunsberg has a comeback rate near 87 percent, and after losing a piece the win rate is still about 51 percent. Losing material is apparently a suggestion, not a verdict. Small wonder that the longest winning streak reached 15 games before the inevitable correction.
Rivalries and Familiar Faces
Nobody plays 43,000 games without making regulars. The most frequent dance partner is Henrik Dalsgaard, with 156 meetings and a near dead-even 73 to 77 with six draws. The series against otrio has been kinder at 50 to 25, while qvalda (25 wins, 55 losses) and humblespaceman (30 wins, 55 losses) have had the upper hand. Favorites like foredi, igorekt, darko11 and ilija_i_oblomov all sit within a few games of level, which is the signature of a player matched against people of similar strength for years.
Clock Watching and Odd Habits
- Best hour of the day is 6 a.m., with a win rate near 70 percent. The 1 a.m. slot drops to roughly 42 percent.
- Monday is the strongest day at about 54 percent, while Saturday is the weakest.
- Timeouts go against gunsberg more often than for (892 losses to 622 wins), which tracks with playing fast and thinking later.
- Nineteen stalemate draws appear in the record, and not a single stalemate win or loss. A strange and specific peace treaty.
- White scores about 55 percent, black about 50 percent, so the first move still matters even here.
What to Expect at the Board
Play gunsberg and you get a d4 opening you probably have not studied, an opponent who is comfortable defending a slightly worse endgame for another 40 moves, and a player who is fully awake at breakfast time. Bring theory if you like. Bring a snack, too, because the average game runs past move 80 and resignation is not coming early.
