Pot-Limit/No-Limit Software

Is there any good software out there good for improving skill in Pot-Limit or No-Limit poker? I'm most interested in Holdem, but I'd also like to work on 7-stud, some Omaha, etc. etc. I've used Tournament Texas Holdem, but I'm interested in something specifically geared to ring play. Seems like it might be an expensive betting structure to learn without some software buddies to practice on...

there is ace of spades software but in my oppinion it's crap. Just use wilsonsoftware for simulating the odds. (you can calculate them as well but when there are more then two players it becomes difficult because of all the backdoor posibilities) You have to learn the rest in reallity I think.

u can have a look at ukpoker (shareware):

I have not registerd and dont consider myself a good anought player to critisize the sofware.
