As far as bots go, check out this: http://games.cs.ualberta.ca/webgames/poker/

This is probably the most advanced stuff out there and it's pretty much the only programme I know of that's actually done at a university.

I haven't played against any of these, but a colleague of mine has and he beat the bots easily. And he's not exactly a veteran poker player.

There's some stats there and I believe that you may still be able to play against the bots.

In all honesty I have only scanned through the page, though the U of A programme is quite well known in online poker circles, I believe.
