Thanks for the comments guys. I see what you mean about hand 1 being an easy 3 bet when he's likely yo stick around with worse and especially with hands we dominate. I've been looking for spots to tone down my aggresson with AK, because I feel I've been losing value and really just over playing the hand by constantly getting it in vs pre flop ranges like [AA, KK, QQ.] from certains players at this limit.

Maybe this guy is one I can confortably 3 bet.

Hand 2 I chose not to raise flop because obviously It's nice when someone this aggro is going to just keep firing. When he barrells the turn I very nearly raised, but thought that there was simply no need to get it in. Reason being, he'll bet or pay me off on the river anyways and If I hit my flush, I can stack his hands that beat top pair and possibly fold if I don't and if his bet size tells me I'm screwed.

Getting it in is probably good though, I mean I know villain is a spewing stationy wierdo yet I'm maybe not exploiting that to the fullest by not getting it in. One thing though is that I'd being playing pretty fit or fold vs him and if he's noticed this he'll probably fold to any sign of aggression with less than top pair, but idk maybe not.
