Bet more on the flop, like $2,5-3,25. You have to call a raise on the flop but it's getting tricky on the turn since you don't want a flushdraw to get a freecard. I guess a 2/3 bet on the turn is good. (fold to raise)
River I would checkfold a spade and blockbet 1/3 if it blanks.
As played you could just make a blocking bet on the river like ~$12 and obv fold to a raise.
I must say it stinks flush...
