Casper Liu, FIDE Master and Bullet Specialist
Casper Liu, known online as Casper, is a FIDE Master whose chess career is defined by speed, persistence, and a suspicious ability to make complicated positions look perfectly reasonable with only seconds left on the clock.
With Bullet as a preferred battlefield, Casper has built an impressive online record while also competing across Blitz, Rapid, and Daily chess. Their strongest results suggest a player who is comfortable trusting calculation, instincts, and the occasional well-timed practical trick.
A Fast-Rising Online Career
Casper's recorded chess journey began in 2019 and developed steadily over the following years. The biggest acceleration came in the mid-2020s, when their Bullet and Blitz performances reached elite online levels. Casper's Bullet peak reached 2839 (2026-08-16), while their Blitz peak climbed even higher, making the clock almost as dangerous as the position.
Across the available records, Casper has scored 475 wins in Bullet and 1,916 wins in Blitz. A longest winning streak of 15 games also shows that this is not merely random speed chess chaos. There is a plan in there somewhere, even if opponents often discover it only after their flag falls.
Opening Repertoire
Casper's opening choices reveal a creative and flexible player. The Nimzo-Larsen Attack has been especially successful in Bullet, including a 76.19% win rate in the Classical Variation. The Caro-Kann Defense also appears frequently, offering a sturdy foundation for fast counterplay.
Casper is not afraid of sharper territory either. The Sicilian Defense, including the Najdorf Variation, features prominently in Blitz play, while unusual choices such as the Amazon Attack and Amar Gambit add a little spice to the menu. This is a repertoire with enough variety to keep opponents guessing and enough ambition to keep engines busy.
- Nimzo-Larsen Attack: one of Casper's most effective Bullet weapons.
- Caro-Kann Defense: a recurring choice for resilient positions.
- Sicilian Defense: a frequent source of dynamic Blitz battles.
- Blackburne Shilling Gambit: particularly successful in Casper's Rapid games.
Playing Style
Casper's statistics point to a tactically alert, long-fighting style. Games average close to 79 moves in the broader record, and the endgame frequency is remarkably high at nearly 80%. That combination suggests a player who is happy to keep squeezing after the opening fireworks have faded.
Casper also shows a strong comeback rate after falling into trouble. Their results after losing a piece are surprisingly competitive, a useful skill in Bullet where a bad move can arrive before the brain has finished loading the previous one.
The data gives Casper a slight edge with White, but the overall record remains competitive with either color. Their most common checking piece is the queen, although rooks become increasingly prominent in later years, hinting at a growing comfort with active endgames and open files.
Notable Online Rivalries
Casper has played 59 recorded games against myburger, winning 37, losing 18, and drawing 4. The rivalry with lukas2006 is also substantial, with 49 games and a 34-14-1 record in Casper's favor. Against viggohilbert, Casper's record is particularly striking: 18 wins, no losses, and one draw.
These recurring matchups provide a useful snapshot of Casper's competitive character: persistent, practical, and apparently unwilling to let a familiar opponent enjoy a quiet afternoon.
- Frequent opponent: Vitus Bondo Medhus
- Another major matchup: Lukas Iskos
Legacy and Outlook
As a FIDE Master, Casper Liu combines recognized over-the-board strength with an online identity built around speed and adaptability. Their rise from strong early results to elite Bullet and Blitz peaks makes Casper a compelling modern chess profile.
Whether the next challenge is a sharp Nimzo-Larsen Attack, a stubborn Caro-Kann Defense, or a tactical Sicilian Defense, Casper's opponents can expect the same basic problem: the position may be complicated, the clock may be nearly empty, and Casper will probably still be calculating.
