Villain was 29/19 over 51 hand sample.

Should I be raising flop?

Should I be betting turn?

Folding river?

Wp imo

I like the flop raise, his donk lead on this decently wet board looks like value or a scared draws and I feel like we're getting great odds against his continuing range vs our raise. Lots of pairs and draws that villain probably won't lay down.
I like the turn bet, obviously his flush draws got there but that's a small part of his entire range and we still want to get value from all of his draws and one pair hands that might have improved their equity with the third spade.
River fold seems pretty standard. What do we beat? Would he be betting his pair of
kings or queens here? Probably not and we lose to the rest of his value range. Only thing we could really be doing on this river is bluff catch and I just don't think villain has enough air here or missed draws he turns into bluffs.
