hand 1: raise $3 pre, and snap call the AI.

hand 2: put in a 4-bet. As played its fine.

hand 3: fine. lead out the flop some, but i see your reasoning here.

hand 4: i dont like this line at all. C-bet this HU almost always. Youre right about not counting on villain to kn0w you are playing nitty, and i expect you to get looked up here quite a bit.
