Here's a situation that I run into occasionally that confuses me. I was playing 100NL 6 max today, 100 BB stacks. UTG limps, player who has been pretty quiet limps, button limps, SB folds, I'm in BB with 55 and check. Flop comes Q52 rainbow, I bet $4, quiet player calls, everyone else folds. Turn comes a 7, completing the rainbow. I bet $8, quiet player calls again, river pairs the board with a 7. I bet $15, quiet player raises to $40. I should just push this right?
