7 handed table, you are in the big blind with 9,300 chips (plus 250 on the table). The blinds are currently 150-250.
There is an early limper plus the button also limped. You have

and you check to see a flop.
The flop comes down

, you check. The early limper bets out 400. The button raises 2000 to a 2400 total bet.
Before you have a chance to act, the early limper puts his stack onto the table (which totals 2000, just enough to call the original bet so any extra you might put in will create a side pot between you and the button).
If you call the 2400, you have 6900 chips left.
What do you do?
