I've been working on such a project on/off for about a month.

Designing an AI pre/flop and flop strategy based on EV calculations and heuristics is pretty trivial. Turn and river actions are even more straightforward.
I find the most difficult portion to design is the "tracker". The toughest part (and it's a major problem) is the difficulty in finding "maniacs", "calling stations", etc. and finding a precise adjustment to the bot's default play in these scenarios.
