Sorry if a thread like this already exists! I'm a USCF 2000 player who dabbles in poker a bit and would be very interested in seeing a comprehensive list of players (and learning their stories) who kick serious ass at both poker and chess.
Of course, the Allen Cunningham thread inspired this, but I'll start with listing a few players I know of:
Dan Harrington - Author, two WSOP bracelets, crazy good at chess (2355 USCF).
Ylon Schwartz - dude is like 2300 USCF and placed 4th in the 2008 WSOP. Also just won a WSOP bracelet, taking down the $1500 HORSE event for over 250k
Jeff Sarwer - Former child prodigy with an extremely fascinating life story.
