AKs hand, TPTK

[atomicbran]

I just moved up from 1/2 and I'm trying to get used to the more aggressive game. I'd never played with any of these people before.

When it comes to me for 2 sb, do I assume I have the best hand? This seems like a raise or fold situation, although I can't protect my hand if it is best. So it's capped and a flush draw might have gotten there on the turn. Do I fold here or call down? I didn't really like anything in this hand.

Though it suck I dont think this can be played any different.
Part of me wants to coldcall the flop to raise turn, but another part thinks that it may not be bet on the turn and some of the limpers may fold if I raise the flop.

Turn and river are straightforward.
