The Fast and the Furious
Deysi Cori, an International Master who earned the title from FIDE and competes online as dey2580, treats every chess game like a sprint. Given the choice between a slow positional grind and a frantic bullet scramble, her online history answers clearly: give her the fast clock. She has fired off thousands of games, and her rise to the top has been as quick as her moves.
Her peak blitz rating reached 2743 (2026-03-26) in 2026, with her bullet rating peaking at 2687 (2026-05-02). The steady climb is captured in
, which shows a player who rarely stays still for long.A Repertoire Full of Personality
Deysi does not play it safe. As Black she happily steps into the French Defense or the Modern, while as White she steers opponents toward Indian Defense setups such as the Przepiorka Variation. She also collects rare lines the way others collect trophies: the Döry Defense, the Amar Gambit, and the wonderfully named Wiedenhagen-Beta Gambit all show up in her games.
Her most dangerous weapon might be a London System arrangement with a poisoned pawn twist, where her blitz numbers hover near a 74% win rate.
Rivalries and Rematches
Deysi is fearless when it comes to rematches. She has crossed swords with Harika Dronavalli 28 times and Antoaneta Stefanova 26 times, grinding out tight series against both. Even when David Howell proved a stubborn rival, she kept returning for more instead of dodging the pairing.
Fighting Spirit
The stats describe a battler. Deysi once strung together 21 straight wins, and her book of comebacks is thick: she recovers in about 85.61% of difficult positions and still wins nearly half her games after losing a piece. She also lands the first check in roughly 61% of her contests, usually with the queen leading the charge.
