We are on the bubble and I have 77 and only check behind because I find the SBs limp suspicious. After hitting my set on the flop I just call his bet. On the turn comes the Jack of diamond, making straight and flush possible. The SB checks and I have to decide if I bet here for protection/value or check behind to prevent a check/raise and see what the river brings. So what do you think? Should I bet? And if so, how much? What do you think of the preflop check and the call on the flop?
