Steal from BB doesn't quite go according to plan....

[kenny7]

Live tourney,$80 buy in.We are down to 2 tables,8 people at my table,top 7 pays,so far from money.BB 1k.I've got just over 60,SB around 65,everyone else is in the 30k range.

SB is a solid young player.Have played with him before and he is very aggressive,both post and pre,certainly capable of making moves.Likes to steal and resteal,but whenever he gets involved in a big pot,he seems to always have the goods.

OK,the actual hand;

2 limpers in MP,SB completes.I'm BB w A [img]/images/graemlins/diamond.gif[/img] 9[img]/images/graemlins/spade.gif[/img]

I make it 7k.Limpers fold,SB calls.Did not expect that.

Flop 9[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/club.gif[/img] 2[img]/images/graemlins/diamond.gif[/img]

I'm happy,SB checks,I bet 12k,SB goes all in. Me???

What can he have here?This seems like a great flop for me,and usually with an overbet like this,people are on a draw,however,since I have the Ad I can't figure that to be the case.

Maybe this is totally standard,but I honestly had no idea what to do here.
