His Play Poker Like the Pros audiobook. It works rather nicely on cash games and is way less volatile than a smallball approach. (My smallball needs more work).
Anyway, winning pretty regularly on micro stakes limit and no limit hold'em. I still have hardly any bankroll at Partypoker, though... I have about $10 at Titanpoker, gained as a bonus, and about $50 at William Hill poker - likewise, a bonus. This one from PokerStrategy.com.
I also play at RAY Poker, where I have about 1.2€, won from freerolls.
Partypoker still has the best software, IMO.
