flopped set

[Kimpan]

UTG is 18/15/1.8 over 213 hands..
Went for a CR on the flop thinking he probably c-bet and I can trap SB.
Felt unsure of how to play this postflop...

I like the flop line. But raise it closer to pot size for protection against flushdraws and to grow a pot. Make it 8.

Turn card isn't pretty. I cross my fingers and bet more, though. So I can protect in case he has a single diamond.

River is ugly too, but you need to bet to avoid a negative freeroll since you are compelled to call here, imo. I don't think that UTG stayed around to catch 9J for a KQ in the hole. So I don't think he has a straight. Maybe a flush or a bigger set. Both is pretty unlikely so you will have to call a bet and pay him off. So don't let him check behind his mediocre hands.
