looks that way to me...MP has aces full very very often

For < 1/3 pot, I'm going to pay this off. I think this could easily be another 45.

I am tempted to call too.

What's MP's stats?

I think folding is correct, but it's damn tempting. I probably pay it off out of curiosity.

Im not sure calling the raise pre-flop from BB is correct.

I don't like your lead on the flop with that many people, as you are basically giving away your hand IMO. A check-raise would probably have been better. As you played it, I think you have to call the river bet.
