It definitely looks like something you are drawing to when you call down 2 streets here and I think a lot of people at the micros are afraid when flushes hit so I think this is a profitable move.

fold the flop

I dont like this bluff you dont block any hearts and he has position on you.

This bluff usually only works with backdoor flush runouts, which can be very profitable if you have enough pot equity (top set) to call made-straight bettors; you got very lucky here.

I think this is a profitable shove against a player who dosen't use blockers + fd combos to starting bluffing in this case, ie. ATTx with hearts. Often enough you get a fold by doing this. I think all flush-compliting rivers should be moved in against a recreational player, but against a regular you should just move in every boardchanging river, just to balance it up :)
