MP3 is a very loose player (51/0) but becomes aggressive postflop. He loves to make tricky plays like check-raising on scare cards at just the right moment to try to get people to fold.

SB is a typical fish LP-P (54/3). I figure I have him beat as he probably has Ax.

Fold this one and think nothiing off it...
You might have the best hand here but the reverse impied odds make this a clear fold...

I would most likely call the flop and raise the turn, (if I'm fairly certain he'll bet out again), unless another heart comes off.
