AK - push pre flop w/1all in or just call?

[jackdaniels]

Early in $5.50 w/27 players. BB is very loose and will call a lot. SB is very similar (both tangled in 1st lvl w/ATo UTG and UTG+1 for 10BB preflop and got it all in on a A56r flop).

MP2 (t3485)
CO (t660)
Hero (t1850)
SB (t744)
BB (t1863)
UTG (t1225)
MP1 (t2203)

Preflop: Hero is Button with A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img].

Do I just call here hoping to eliminate SB or should I push and (likely) gamble here for a bunch of chips? FWIW I was pretty sure that if I pushed, BB would call with anything (small pair, Ax, 2 broadway etc.. - whatever he might have). Him having a AA/KK here can happen sometimes as well I guess.
