Live 2/5 game, Miami (i.e., quite a few loose players in the game). I have JdTd in big blind.
The villain is in cutoff, and is capable of playing any two cards. His bluffs were picked off twice in one hour.

Pf: Utg limps, the villain limps, button limps, sb raises to $20, I decide to call $20, everybody calls (yep, that's Miami for you).

Flop: 3 hearts - Qh9h6h, everybody checks, still $100 in the pot.

Turn: Kc, so I have my straight on this dangerous board. Sb checks, I bet $65, utg folds, the villain jams for $280 effective, button and sb fold.
I need to call $215 to win $660. Does he have the flush 2/3 of the time in this spot?
