Yichen Han (aka ProfessorChess101)
International Master Extraordinaire
Meet Yichen Han, a grand tactician of the 64 squares who proudly dons the title of International Master granted by FIDE. With a penchant for blitz and bullet, ProfessorChess101 (because even grandmasters need a cool alias) has turned the chess battlefield into their playground.
Yichen’s journey through the ranks is nothing short of a rollercoaster — hitting a blazing peak blitz rating of 2947 in January 2025 and an electrifying bullet apex of 3051 in mid-2021. Their rapid rating soars to a respectable 2579, proving that Yichen is equally comfortable in thoughtful duels and lightning-fast skirmishes.
Their playing style? Oh, it’s a unique cocktail: a low early resignation rate (3.3%) that says “I’m in for the long haul,” with an impressive love for the endgame (73% of games run the distance). Average winning games span around 70 moves, meaning you better bring your stamina — and your popcorn.
Yichen thrives in the comeback department, boasting a stunning 83% comeback rate from sticky situations, and holds steady with a solid 53% win rate even after losing a piece. So yes, if you think you caught them off guard, buckle up — the IM has tricks left in the Pandora’s box.
Rivals beware: Yichen dominates notable opponents, with win rates hitting 100% against many and a respectable 62% versus a top sparring buddy, “ludogorec.” With a longest winning streak of 32 games and a tactical mindset that blends patience with sharp strikes, Yichen redefines resilience.
