Initially, I was thinking, just call the flop. I don't really like pushing because I felt that would only get you called by made flushes and maybe a hand like K [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/club.gif[/img]. You have no redraws against a flush, and your something like 57/43 against a pair with a draw.

However, you can't let BB stick around. If you just call, your giving him 6 to 1. I would put him on the heart draw after he check-called a pot sized bet. I would 3 bet to price out BB.

Another thing. As played on the flop, why didn't you raise the turn? He bet 5 into a 40 something pot. That signals weakness and/or flush draw to me.
