HERO checks, westopresto checks, MOMLASAM bets $65, yuleekooly bets $130, HERO ?

First, on the call, I was getting 7 to 1 and I was only playing on if I hit the flop hard. Second, some reads -- yuleekooly and MOMLASAM had already coldcalled a few 5bb raises and got pretty out of line postflop. Although we had only played about 10 hands, they were easily 2 of the weakest 3 players on the table. I checked because I knew at least one of them would bet.

How do you play it?
