AK seems to be something i have trouble with but you guys have helped me alot. I want to see if I played these 2 hands right.

First one Villain was 15-4 over 175 hands I had notes on him that he slowplays Large PP examples were raised to.12 with KK and to .08 with QQ.

Is this how you would play the draw?? Is shoving the river optimal? or does it look like i have the nuts??

Second Hand I had no reads on this guy at all the hud for him had not came up yet and he left after this hand.

UTG+2 checks, Hero bets $0.47, UTG+2 raises to $4.30 all in Hero?????

After he check raised all in I tanked I was thinking he had either hit a set, had AK too, had spazzed out with KJ, or had complete air. I discounted AA b/c he didn't raise me pre. Is this line of thinking correct?
