Villain is somewhat new to the table and is a grouchy older man who reads the newspaper while playing and complains of other people going too slow when he's one of the slowest people. Your typical douche bag that can get tricky like just calling with the nut flush on the tun and tries to check raise on the river when the 4th of the suit hits.
To the hand: 1/2 NL at the Taj. Villain limps UTG, 1 more limper, I limp with 55, 1 limper behind and both blinds.
Flop is 567 rainbow. Checked to me and I bet $15, SB calls and villain takes time and calls.
Turn is A that puts backdoor draw out there. Checked to me, I bet $60 into an almost $60 pot. SB folds and Villain deliberates and eventually goes all in for $113 more. I barely have him covered. By playing with him the last 2 rounds, I'm pretty sure hes got a decent hand with the way he did it but didn't necessarily think the straight. Maybe 2 pair. I call. He flips 89s for the nuts and I don't pair up on the river.
Thoughts on this hand? I don't want to check behind on the turn to give any striaght draws a free chance. Is this just inevitable?
