$200 SnG AK in the big

[FoxwoodsFiend]

I have 890, CO has hero covered, button has 430. Button is a reckless player, but I have only seen him at this table. Anyway, blinds are 15/30 and I get AKo in the big. Folded to CO who makes it 100. Button moves all in for 430. SB folds.
What's my move?

I'd be moving all-in. But, I wouldn't be thrilled about it.

Why not? You're up against a steal position and an aggressive shortstack with a hand that is no less than 45% to win against all but 6 of the best hands your opponent could have.

If you push, what hands would CO call with? Unless he's loose, probably a premium pair (maybe AK).

Most players don't open-raise premium pairs to 3 1/3 the BB from the CO. The reckless button player could be pushing a lot of worse Aces that you're a big favorite (as reckless players on a shortish stack are apt to do) - maybe even some worse Kings, random cards, etc - you're probably a pretty darned good favorite against his range of hands, with a nice overlay if CO drops out.

I say push and live with the consequences (absent some additional info on the CO).
