I have Poker Academy and love it. It lets you adjust table structure and type of opponents so that you can practice different types of Holdem without paying for the lessons like you would playing for cash. The computer opponents are pretty solid and have a nice variety.

Any advice on computer based software (not stuff like poker stars fee money)? Which is the best? I see it as a lot better than the online play money tables because it isnt filled with people calling wih 2,6.
