Awkward AK allin

[Bosox]

5/10 NL short on party

Information:
I have been sitting for just five orbits or so. SB has been playing loose and wild and has gone to showdown with some rediculous hands. He's clearly tilting and has gone allin with an inferior hand in bad position 3 times so far. UNKNOWN looks equally bad but less obviously so.

Just a few hands ago: SB bets 90 UTG with JJ, called by same UNKNOWN as my hand. Flop KTT and he just goes allin for 700, the UNKNOWN actually calls with 77. The UNKNOWN reloaded.

ME: $1000
SB: $1500
UNKNOWN in Late Position: $1000

I get A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/club.gif[/img] UTG, I bet out $35.
UNKNOWN calls,
SB calls,
BB calls but folds flop.
FLOP: 9 [img]/images/graemlins/spade.gif[/img] k [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] (Pot $140)
SB bets out $90,
I reraise to $250
UNKNOWN calls
TURN: 2 [img]/images/graemlins/club.gif[/img] (Pot $900)
SB goes allin for $1200

ME and UNKNOWN are sitting with 700 left.


Now what?
