i'd say poker. i was a chess player before i got into poker as well, and i used tournament winnings from chess to start playing poker.

the reason I say poker, is that chess is about memorization more than anything. While having a good memory is important in poker too, the chess board is static, whereas you must constantly adjust to unique opponent's tendancies. the key to being good at chess is recognizing similar positions you've been in before and using the information you already know in order to make a good decision. if you are up against an unknown in poker, its impossible to do this, and you must adapt quickly if you want to win.
