Diego Lanza: The Marathon Man of Blitz Chess
If chess handed out frequent flyer miles, Diego Lanza would have his own lounge. Playing as lanza1834 (born 1834, allegedly, which would make his stamina even more remarkable), he has logged more than 42,000 blitz chess games since October 2011, stacking up over 20,000 wins on the long road from a 1352-rated rookie to a peak of 2384 (2026-02-10). That is a fifteen-year expedition completed three minutes at a time.
The story underneath the score is simple: Diego does not do shortcuts. His wins average 76 moves and his losses around 80, more than 80% of his games wander into an endgame, and his early resignation rate is famously forgiving. Opponents hoping for a quick white flag are advised to pack a lunch.
The e4 Empire: Diego's Opening Repertoire
Diego is a 1.e4 player with the reliability of a metronome. In a typical year, the King's Pawn accounts for about 99% of his first moves as White; d4 appears roughly once per season, apparently just to prove he remembers how it moves.
That loyalty funds a deep toolbox. With White he has built careers out of the Sicilian Defense in its Alapin and Closed forms, the French Defense: Exchange Variation, and above all the Caro-Kann Defense, his most dependable workhorse at better than 55% across more than 2,000 games. When he wants a change of pace, he reaches for the Scotch Game, which opens like this:
Black duties are handled by the Australian Defense, played over 2,600 times without anyone ever explaining the kangaroos, the seductive Blackburne Shilling Gambit, and the Italian Game: Two Knights Defense. Variety, in moderation, like everything else in his chess.
Grinder by Design: The Playing Style of Diego Lanza
Diego's profile reads like an endgame manual with a sense of humor. His comeback rate sits above 83%, he almost never loses a game in lopsided fashion, and even after dropping a whole piece he stays afloat in close to half of his games. He is patient before the bloodletting too, waiting an average of seven moves before the first capture hits the board.
His favorite attacker is the rook, which delivers more of his checks than any other piece. Meanwhile his opponents produce about 3.27 checks per game against his 2.31, which is quiet chess by blitz standards. The clock has also worked plenty of overtime for him: more than 6,000 wins by timeout suggest that a lot of opponent flags fell while he calmly pushed pawns.
Time of day matters. Midnight is his golden hour with a win rate north of 51%, while 4 AM collapses to roughly 32%, presumably played by a different Diego entirely.
Familiar Faces: Diego's Most Played Opponents
After 40,000-plus games you collect regulars. dumbledore233 has met him 46 times in a photo-finish series that currently leans 22-20 the other way. rdors is the friendliest assignment at 22-13 in Diego's favor, while Sasha Ivanov and flavian gab have donated plenty of points over the years. Then there is zlatkosavica, the designated nemesis, holding an 18-10 edge. Diego keeps coming back anyway, which is either loyalty or the slowest revenge plot in chess history.
The Fifteen-Year Climb
The graph below is a decade and a half of stubbornness rendered in one line. He cracked 2000 briefly in December 2016, dipped, then made it stick for good in 2018 before surging through the 2100s and 2200s in the 2020s toward a February 2026 peak. He has proven himself in other formats as well, with a rapid peak of 2211 and a bullet rating that shall only be discussed in whispers (it is 1632, but he had a good time).
Diego Lanza by the Numbers
- Longest winning streak: 13 games. Longest losing streak: 14. The chess gods keep a very fair ledger.
- Tilt factor: an enviably low 14. Possibly the calmest man ever to lose on time twice in a row.
- Nearly 60% of his games against lower-rated opponents end in wins; against higher-rated ones, life gets philosophical.
- Casual games agree with him far more than rated ones, which raises friendly questions about what "casual" means around here.
- Bullet chess output: 12 lifetime games. Some people simply refuse to sprint.
- 3,022 blitz draws, each one presumably fought to the last move, because Diego does not do anything quickly.
In summary: open with e4, refuse to resign, and never, ever schedule a rematch at 4 AM.
