theres no way to know if he got the flush on the turn without a bet, i'd check on the turn to see if i boat up on the river, but since he checked again i would throw out a bet and fold if i get played with. your kicker isn't that good but i think this play is ok for a mediocre strength hand.

I really like your play here. Keep that pot small on the turn and river; when you have a bad kicker and the flush is out.
