I feel like I played this hand fairly decent but of course losing chips is never a fun thing. My Cbet was maybe a bit too large but I would usually bet larger like this with a queen to charge the flush draw. With this wet of a board and the villain showing so much interest would you maybe be more cautious? It was a semi bluff with the gutshot but I can't really see villain folding whatever he called pre with.
Here are some of villains stats, unfortunately we only have 18 hands on him. This is the first time he played back at me but with such a small sample we can't really take much from that.
