Marlon Steven Aspiazu Sibri: The Bullet Board General
Who Is AspiazuMarlon2001?
Marlon Steven Aspiazu Sibri, known online as AspiazuMarlon2001, is a FIDE Master who has made his name in the fast lanes of online chess. While the FIDE Master title speaks to his classical credentials, his true kingdom is the bullet board, where his peak rating of 2703 (2026-07-30) puts him in elite company. His blitz rating is just as fearsome, peaking at 2702 (2026-06-14).
A Meteoric Rise
Marlon's online journey began in May 2020 with a blitz rating of 1576. Within months he crossed 2200, and by the end of 2020 he was already near 2400. The climb continued through 2021 and 2022, with a side quest in rapid chess that peaked at 2481 (2022-04-19). By 2026, he had broken through the 2700 barrier in both blitz and bullet.
The English Opening Devotee
If you face Marlon with the white pieces, you know what is coming: 1.c4. The English Opening is his signature, appearing in thousands of games. He favors the Four Knights System, Nimzowitsch Variation, the Symmetrical Variation with the Botvinnik System, and the Mikenas-Carls Variation. As Black, he is equally loyal to the Modern Defense and the King's Indian Defense, often steering games into rich, strategic battles. His games are surprisingly long for bullet, averaging over 80 moves per decisive game, and he reaches the endgame in 86% of his contests.
Comeback King and Marathon Man
Marlon's style is defined by resilience. He has a comeback rate of 85.57%, and he wins 46.32% of games even after losing a piece. His longest winning streak is 29 consecutive games, a testament to his ability to enter a zone and stay there. He is also a night owl: his best results come at 22:00, when his win rate jumps to 52.28%, and Sundays are his strongest day of the week.
Rivalries
No biography would be complete without mentioning his fiercest rival, BowtoBroda8562, who has faced Marlon 128 times. Marlon holds a narrow but positive record of 67 wins, 54 losses, and 7 draws. He also has a long-running series with Pri (49 games) and marquezangel1990 (41 games), proving that online chess is as much about relationships as it is about rating points.
Bullet by Nature
While his blitz and rapid results are strong, the data makes it clear: Marlon is a bullet specialist. His bullet rating peaked at 2703 (2026-07-30) in July 2026, and he has played thousands of bullet games, with a win rate that hovers near 50% against elite opposition. His preferred time control is bullet, and his play reflects it: fast, tactical, and relentless.
