I'm trying to think who might know poker to teach you and I feel like Sam Winchester used to play it when we had the nights, Malcolm Reynolds might also, although I've not gotten to talk to him much since his return here. There are probably a lot of people who could teach you that I just don't know who exactly. You'd like it though.
