Big blind hand on the bubble

[bruce]

Last nights 25k guarantee on PokerStars ($10 rebuys)

Down to about 150 players left. Blinds, I believe are 600/1200 and there is one limper and small blind completes his bet. I have 85o in big blind. I have everyone covered roughly by twice the amounts.

Flop comes 8c 3h 2h. Pot now roughly 4k.

Check to me and I bet 2100. Limper folds and small blind makes it 4000. I call.

Turn 8c 3h 2h Ac

Small blind moves in for around 16000. What's my play?
I have around 38000 left.

Comments appreciated.
