*grunch from the cheap seats*

It looks a little passive to me. I guess opponent could have 67 or A2 here but I have also seen people reraise with a strong draw.

I don't think its a big mistake but I would probably 3 bet the flop and see what the opponent does. If he calls I would go ahead and bet the turn.

The other choice would be to call the flop and check raise the turn with the non heart.

The 3 is not really a scare card so I would bet/call here.

Any 3 bet and I would call down.
