PF is good. I bet more on the flop (maybe like .55-.60) If villian is willing to call big bets without correct odds to do so then take advantage of this. As it happened, he was getting almost the exact right price to draw to the flush or the OESD. (And even better given his implied odds against you) The turn and river bet are small but I understand. You have a good but vulnerable hand against loose players but getting almost 8.5-1 I think the call is good.

A blocker bet is when you throw a smallish bet out with a hand that might be beat but you want to see a showdown and think your OPP will put a bigger bet in if you check.
