I'm kind of torn in this spot.

In terms of a bluff, I obviously like it better that we can now represent something (as in a backdoor flush).

Though once he calls the turn raise, which wasn't that large, I'm not convinced that he didn't have some kind of draw (hearts, or straight draws) himself.

I don't even mind flatting the turn sometimes. If he's double barreling and folding on the turn, he's probably folding worse only. I'd like this better with a hand like 68 than AJ.
