110€ live rebuy, fold AK preflop headsup???

[KSakuraba]

100+10€ rebuy tournament at local casino, ~150 players, top 9 get paid. Players remaining ~100.

Villain has just joined the table so my only read of him is that just after seating he limped in from MP, i raised 4xbb from sb and he folded.
An orbit later im in UTG+1, reraise UTG small stack all-in with QQ and lose to AA.

So the real question comes from the hand right after that. Im still the 2nd largest stack at the table with ~7500, only villain covers with ~10k.
avg ~6k, with blinds 200/400, going up to 300/600 in a minute.

To make the long story short:
Hero(UTG) raises to 1200 with A[img]/images/graemlins/heart.gif[/img]K[img]/images/graemlins/club.gif[/img]
folds to villain who makes it 4800
folds to Hero, who...????

The amount of the raise confused me...i first thought of it as a strong statement of him not wanting me in the pot but on the other hand i thought he could think im steaming from the last hand and try to stack me with a premium hand knowing i might call with weak holdings. Or am i overthinking,should this be an easy push because of the steepness of the structure(30min levels, the one after 300/600 is 500/1000)? [img]/images/graemlins/confused.gif[/img]

Thanks guys,
