I very much enjoyed version 2, but found version 3's AI to be severely lacking. It was too easy for many of the computer players to go 'all in' during Texas Hold 'Em.

If you want a decent competitive version of No Limit Texas Hold 'Em, then try DD Tournament Poker: No Limit Texas Hold'em at http://games.donohoedigital.com/poker

I'm not connected in any way except a very satisfied purchaser. There's a trial/demo version that can be downloaded.
