50$ MTT ongame ITM, resteal with AJ?

[plzbenice]

50$ mtt ongame(european daily), average to fast structure, bad players in general but i guess decent nearing the end.

blinds 800/1600, no antes.

i have 20K and im dealt AJo in the bb.

folds to the CO who has 17K and minraises.

mustshove with no reads? 3.2K+1.6K+800=5.6K in the middle

dont know anything about the player.

we are in the money, 479 starting, 60 paid, 40 left. going out now is 107$ or so, first is like 5500$.

average stack is between 15-20K somewhere.
