Arima Kousei: The FIDE Master of the Digital Chessboard
Arima Kousei, also known in the online chess realms as ElMosho7u7r, proudly holds the title of FIDE Master bestowed by the global chess authority, FIDE. A tactician with a flair for the dramatic, Arima has earned a reputation for both brilliant comebacks and an uncanny ability to keep their cool when the pressure mounts—boasting an impressive 99.2% win rate after losing a piece. Yes, that's not a typo; this player treats lost pieces like bad hair days—just a minor setback before the comeback!
Playing Style & Personality
Known for an adventurous yet calculated style, Arima relishes endgames, appearing on the battlefield in over 71% of their matches. Their games tend to be marathons rather than sprints, averaging 80 moves per win, proving patience is indeed a virtue. Early resignations are rare (just under 9%), suggesting a fighter’s heart that rarely quits prematurely.

Their blitz profile is robust with over 470 wins from 865 games using an opening strategy they cryptically call "Top Secret". Spoiler: it probably involves a mix of frustration and checkmates!
Achievement Highlights

- Current winning streak: 2 games (hope it continues!)
- Win rates by color: A slight edge with White at 50.78%, but not to be underestimated when playing Black at 47.04%
Opponents Beware
