30+3 all in hand

[ray holmes]

30+3 at party. 177 players, paying 160. I'm in the small blind with AKo and an average stack of 4100. Blinds are 300-600. EP limper, folded to cutoff who raises to 900. Button folds and it's up to me. I figure I have to get a hold of some chips to move on up the ladder and this looks like a good spot. Limper might have some kind of pair and it looks to me like the cutoff may be trying to pick up the pot. I had just moved to this table and didn't have any info on anyone. Limper had 6000 and raiser 12000. I move in, limper folds, cutoff thinks a long while, calls and shows AQo. Q comes on the flop and I'm gone. What say you about my play?
