Playing 1-3 nl @ Parx Casino in PA. At the start of the hand, I have about $320. I’m in the BB with 57o. 4 people and SB limp and I proceed to check. $18 in the pot. Flop is 2 3 6c rainbow. SB and I check and person to my left bets $5. 2 people call as well as I. $38 in the pot. Turn is a 10c. 2 clubs on the board. We all check around. River is a 4. I bet $20 and it folds around the gentlemen in the 9 seat. He decides to raise me to $40. I take about 20 seconds before I re-raise to $120. 9 seat pretty casually, but quickly says he is all in for $275. After scanning the board quickly to reconfirm that I have the nuts and immediately call, showed my hand and raked in the pot. He openly mucked K5.

In this instance, I did get max value for hitting my gut shot. But, how would have played the hand differently against a more experienced player?
