NL25 KK with A high flop

[PoliticalRefugee]

Ok, firstly he's played a stupid little min raise so is $1.5 ok here? It's what I usually do.

On the flop i doubt he'd holded 45 and theres no flush draws out so the Ace is my only problem. Now I dont like raising because I only get called by an Ace or a bluff which could ultimately make me fold. I check hoping he's holding JJ QQ or something which will make him bluff the turn.

Now he's bet the turn do I call/raise or fold.

1) Folding I don't like, I've showed weakness on that flop so he could easily be betting
2) Calling, I like this here as I can then call a moderate river bet that he might be making with a lower pp. If he bets hard then I probably fold
3) Raising, surely if I raise I'm chasing out the hands that will try and bluff me on the river and asking for trouble from the hands that beat me, i.e. any Ace?

Anyway if someone can comment on my thought process that would be great.

Cheers
