Yulia Efremova: The Woman International Master Who Never Blinks
Yulia Efremova, known online as JuliaEfremova, is a FIDE Woman International Master with the soul of a bullet chess berserker.
Profile
Yulia Efremova earned the Woman International Master title from FIDE, but her online career has been defined by speed. Since 2019 she has piled up thousands of bullet and blitz games, reaching a bullet peak of 2399 (2026-03-12) and a spectacular blitz peak of 2588 (2026-06-28) in the summer of 2026. Her preferred battleground is bullet chess, where the clock is as dangerous as any opponent.
Her lifetime bullet record is 2130 wins, 2212 losses and 171 draws. That nearly 50% win rate against strong fields is evidence of a player who loves the arena. Her strength adjusted win rate is about 49.9% in bullet and 50.8% in blitz, which means she consistently performs right at the level of her rating.
Style and Stamina
The numbers paint Yulia as a relentless fighter. She rarely resigns early, with a resignation rate under 1%, and her endgame frequency is 83.7%. Average decisive games stretch past 70 moves, even in bullet, showing that she fights for every point until the very last second.
Her comeback ability is scary: after losing a piece, she still manages to win 45.4% of the time, and her overall comeback rate is 88%. She has enjoyed a 17 game winning streak and survived an 11 game losing streak without changing her approach. Saturday is her lucky day, and 23:00 is her magic hour, where her win rate jumps to 81.25%.
Opening Repertoire
With Black, Yulia usually reaches for the Scandinavian Defense, her most reliable bullet weapon at 51.7%, or the Caro-Kann Defense when she wants a sturdier structure. With White she enjoys the chaos of the Amazon Attack and the Amar Gambit, and she scores a mighty 59.2% in blitz with the Caro-Kann Defense: Exchange Variation.
Her repertoire has shifted over time. For years she was an e4 loyalist, but in 2026 she reinvented herself as a d4 player, and her opening variety is huge: the Australian Defense, the Modern, the Barnes Defense, and many unorthodox lines appear in her game history. She is equally happy outlasting an opponent in a quiet position or transposing into a tactical hurricane.
Rivalries
Online chess has given Yulia a cast of recurring rivals. Her most frequent opponent is MaxN0B, with 37 meetings and a 16 to 17 scoreline in bullet. romanetti is nearly as familiar, with the series deadlocked at 11 wins apiece. Aleksandar Dovijanic has the edge with 14 wins to her 9, while AlexxPink has been her toughest puzzle, taking 15 of their 21 games. These rivalries turn every rematch into a small saga.
