Good single player poker games?

[sitontheedge]

Hey all. I wondered if anybody can recommend a fun, single player poker game. I've already played both Poker Night at the Inventory games and that's the sort of thing I have in mind (though if the poker were more mathematically realistic and the game a bit faster I wouldn't complain).

Is there anything else like that out there? The only thing I've been able to find is the poker built into Red Dead--all other poker games seem to be either inherently multiplayer, or really minimal and boring.
