marginal spot $109 AKo in SB

[gomberg]

I'm trying to learn how to be a good tournament player at the moment for a change of pace (noramlly a NL cash game player)...

62 people left, 36 cash - tourney started with ~400. I don't really care about cashing all that much unless I get to the final table.

blinds 400-800, 75 ante. I have an above avg. stack of ~25k.

CO who barely covers me and is playing pretty tight opens to 3200. I have AKo in the SB (BB is playing tight with 12k chips). What's the play?

Notes on CO:
He is a calling station. I've seen him CC then call a squeeze with TT, AQ, etc. 1 round before, there was an early loose raiser and 3 callers (including him), and I pushed an M of about 7 w/ 46o from the BB. Everyone folded to this guy who called with AQs and I won the hand.

Is this a good spot to call and see a flop as I don't really want a race situation? On the other hand, he may call me with AQ again or even something worse because of the hand before...
