Pocket 10's - Push or Call?

[Rockatansky]

Absolute Reward Points Tourney (read: freeroll)

9-handed

Blinds: T50 / T100

Hero (T2382) is dealt pocket 10's in SB

MP1 (T3910), MP3 (T3820) limp

CO (T290) raises all-in

Hero pushes all-in

MP1 folds, MP3 calls.

CO is so short stacked that I'm a definite favorite over his potential range of hands.

I'm fairly certain that neither of the MP players have an overpair; the table has been passive PF so a limp re-raise is unlikely to work.

Best I can figure, I'm probably a coin flip in this situation given the likely range of hands that MP1 and CO hold.

I'm basically wondering whether I should take a 50% shot at more than slightly doubling up relatively early in the tournament. There were 132 players left, top 18 paid.
