Early on in a live $10 MTT.
Blinds are 50/100. 7 handed.
Hero: 4950
Villain: ~13000
UTG moves all in for
1250
two folds
Hero (CO) calls
1250 with A

Q
one fold
Villain (SB) re-shoves ~
13000
At this point the big blind folds and villain seems to think he's heads up with the original raiser, so he flips up his cards and shows 7

7
Action is back on Hero. Hero: ???
I'm getting about 2:1 on a call and I've put ~25% of my stack in the middle already.
But UTG could well be holding some of my outs, and if I fold I still have 37bb (average ~55bb).
Thoughts? Is it worth putting my tournament life on the line when I'm, at best, flipping?
