Flopped 2pr to broadway flop - what should I do

[Damian UK]

Starting chips 1500, blinds 15/30

4th hand of SNG have A [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] in the bb - 4 limpers, SB makes it 120 to play I immediately thought AK, I call (very bad if he has AK), as do all 4 limpers (no surprise there then)

Flop A [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/diamond.gif[/img]

SB bets 210, I raise to 510, 1st limper calls (has played every hand winning 2 without showing by overbetting the pot), all fold to BB who also calls

turn 2 [img]/images/graemlins/spade.gif[/img]

BB checks - so what should I do?

I will post what I did later

Thanks
