Three Cards That Match 5/10 NL

[AdamBragar]

I have basically just started this session. I have a suspicion that the villain is bad, but I can't remember why I think that and haven't really seen him get out of line yet. It could be that I have notes on him at another computer I've been playing on. Anyway, I got very excited because I had 3 of a kind on the flop and top kicker. Also, I float a lot of flops, but on the turn, what kind of hands do I beat? How else should I play this hand?

Online 10 handed

MP2 raises to 45 (730), I (cover) call on the button with AK (suits irrelevant). I definitely mix up calling and reraising preflop with AK. Heads up to the flop.

Flop: K K 4 rainbow
Pot: 105

MP2 bets 125 (yeah, that was weird), I call.

Turn: Q
Pot: 365

MP2 checks, I bet 300, he pushes for 220 more, I scratch my head about how I played this hand and call.

Comments appreciated. I guess my main question is between betting and checking the turn.
