Flop, I don't like the continuation bet against a K on board with nothing in multiway pot. Try to keep the pot smaller unless you have something in multiway pots.

Turn, I'm trying to see the river as cheap as possible with just one card to come, not to put in $36 drawing to a flush on a paired board with one to come.

River, clear check fold, although you shouldn't be there in a pot this big.
