[Sporky]

it sure looks like he's calling you down after that flop raise. he calls the turn when the heart hits. looks like he has a pair or maybe ace high on the flop/turn also possibly a heart.

i think that it's an easy bet. people call down with all sorts of pairs in this spot that they won't bet with but they'll call. with the bet/fold line even the rare times you're bluffed out of the pot with a raise by a weird aggro guy (which he doesn't look like from the rest of the hand) i think the bet still proves to be very profitable.
