PL AKs problem

[GrinningBuddha]

I'm dealt A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/diamond.gif[/img] UTG+2 in a .25/.50 PL game on Prima (don't laugh, I'm still learning PL).

I raise the pot of 2.25 and am called by a late position player. Flop comes down:

Hrm. I can think of better flops given the Ax hands people will call with. I'm focusing of being aggressive in these games one I get a bigger stack, and bet the pot of $7ish. LP calls. Ugh.

My hand improved, but what did he call me with? What do I bet here ($15 pot)?

Results in white:

<font color="white"> I bet the pot and he folded. I don't like the bet, but didn't want to show weakness either. Is there a better option for someone that has every chance of having called for the gutshot? </font>
