AK on the button... that's an insta-hardon.

Preflop: yeah raise more, I woulda done 18-2o myself. I like to get the money in good, but I also like seeing flops with AK. I wouldn't jump in with a $.50 raise in a pot-commit-the-donks rope-a-dope manuever; that move is for AA or KK (works well at these stakes, too).

Flop: I like the cbet. You were a strong pf aggressor, and you're bluffing with as many as 10 outs. It did scare out a couple. Turn was solid too; against the calling stations at these tables, there is no need to get tricky.

River: i would've bet here. You might get a small ace to call... and I don't think this guy is check-raising you. If he had a straight he'd likely have led out the river- either a weak bet (in the hopes that you'd raise) or a large one. The idea of checking a monster on the river and having their opponent (you) check behind is just too frightening, it rarely happens given the typical donks you're playing against.
