Bubble Hand

Yesterday, I was playing in a 55 partypoker STT. And I didn't really know what to do with this hand. (I don't have the HH anymore, but I created him).

Blinds 100/200, 6 players left.
UTG1
Mp1 2200
Mp2 1400
CO 1600
Hero 1200
SB 1100
BB 1500

Dealed to Hero TT. Mp1 folds, Mp2 raises to 700, CO folds.
Mp2 has stolen a lot of pots before. Once he had to show KTos.
Do I have to push this card (Ofcourse he will call, no matter what he has) or do you think I will get a better spot? <font color="blue"> </font> [img]/images/graemlins/confused.gif[/img]
