Lucas Cumpe: The Blitz Machine
Lucas Cumpe, known online as lucumpe04, is a FIDE Master who lives and breathes blitz chess. While many titled players spread their time across classical and rapid formats, Lucas has made speed chess his domain, stacking up more than 2,600 blitz games in 2025 alone. His peak blitz rating of 2922 (2025-11-13) places him among the most dangerous online attackers, and he has also shown elite speed in bullet, peaking near 2767.
Opening Repertoire
Lucas is a devoted 1.e4 player. With the white pieces he has a clear favorite: the Italian Game, specifically the Scotch Gambit and the sharp Anderssen Attack, where he scores a blistering 63.7% in blitz. His handling of the Sicilian Defense is another defining trait. As Black he has faced the Alapin Variation, including the Sherzer Variation, in hundreds of games, and he is equally comfortable defending the French Defense and the Caro-Kann Defense.
Rivalries
No biography of Lucas would be complete without his battles against familiar online foes. He has faced Hikaru Nakamura 38 times in blitz and is still searching for a first win, a scoreline that would test any competitor's patience. His most frequent rival is riley, who leads their 51 game series 26 wins to 19, while alexrustemov has also proven tough, holding 24 wins against Lucas's 14. These rivalries reveal a player who never dodges strong opposition.
Streaks and Psychology
Lucas is a streaky competitor. His longest winning streak reached 10 games, while his longest losing streak stretched to 22 games, a brutal stretch he managed to survive. His tilt factor sits at 22, meaning bad losses can bleed into the next game, yet his comeback rate of 93.79% shows a fighter who keeps believing. He is also a disciplined favorite: against lower rated opposition he wins 67.22% of the time, and his best results come at 18:00, with Saturdays as his most productive day.
Numbers Behind the Style
The data paints a picture of a relentless grinder. Lucas wins 47.53% of his white games and 41.99% of his black games, and his battles run long, averaging nearly 90 moves per win. He reaches the endgame in 87.71% of his games and prefers to outlast opponents rather than deliver quick checkmates. When he lands the first check, he wins 52.38% of the time; when he is checked first, that number drops to 35.89%, proof that initiative matters deeply in his play.
