The only 2 options right now for Bitcoin poker are Sealswithclubs and Betcoinpoker. Seals has active ring games and decent amount of tourneys. Betcoin doesn't really have too many active ring games at the moment but they have a ton of tourneys available now that they joined the Winning poker network. If BJ is a requirement then Betcoin is the way to go, once you deposit to one of their sites you can use the chips between their poker room, casino, and sports book.
Since someone posted a Seals link I'll post a Betcoin ref. link if you decide to use them.
