Re: 3,30+R 10K Stars - Call or not ?
 

He cold-called me preflop. So I guess I put him on A9-AK

I would definately fold this UTG, but since you didn't I think you have to call here. IMO there is a good chance he is on a flush draw, has a king, a smaller pair, or is outright bluffing (he may have thought from previous betting that you would check here). It is unlikely that he has AK and is doing some high level thinking. If he does have an ace either:

you have him outkicked (less likely)
he has you outkicked and you may split the pot

It's a clear pre-flop fold.

But now that you've gotten yourself in this spot, ask yourself what sort of flop are you hoping to hit? You're hoping to hit an ace right? If you're going to play this pre-flop you have to call now. If you're beaten tough luck and maybe it'll teach you to fold A8 utg next time.
