Yup. There are also many more situations in limit poker that have a clearly optimal play than no-limit poker.

In limit poker, you have the choice of check/call/raise/fold, where in no-limit poker the raising is fully continuous and you almost definitely don't have the complete information to make the actual optimal play across the full possible range of bets.

Phil, if you wanted to read the best literature on this, The University of Alberta Poker group (run by the guy who weakly solved checkers, I think?), made a bot years ago that wins 1v1 limit poker against professional players and they keep writing about it while probably winning millions of dollars secretly on the internet. Or possibly they are too true of academics to actually run bots.

They're working on no-limit poker now though, and I'd be surprised if bots haven't passed humans within 5 years. For now, humans still dominate. http://poker.cs.ualberta.ca/publications.html
