One could argue for just calling down from the flop on (folding if a 4th heart falls or if MP2 raises somewhere).

With the bettor on your left you can not protect your hand. By letting UTG bet the hand for you, you lose the least when you're behind and win a nice pot when you're not and your pair holds up. MP2 probably has a heart and isn't going anywhere, so by calling down you get 2 : 1 for each bet you put in.

Is this too weak?
