Ahh, but you have to include the implied odds.

e.g if you have a set or made hand, your calling any bet on the turn that hit him, which moves his % if he has the 7x to 58% and if he has the flush to 76%, therefore making this +EV.

IMO the villain here has some kind of pair and draw hand, id imagine 75 or 78, or if he had the flush draw then A5d, but im leaning more towards the pair and straight.
