5 + 1 Party AKo ITM Decision Hand

[deuces09]

Blinds are 100/200, you are the BB with A [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/heart.gif[/img]

Three players remaining

SB is a decent player who caught an amazing run of cards to get up to 4000'ish by level 4, but I doubled up through him with AK against his K9 when he tried to steal and got pot committed with my all in reraise with 3 remaining

My stack is 4200, SB has 3200, Button has 600

Button moves in for 600, SB calls the extra 500

Do I call here, raise the pot, or push?

What I did is below:

<font color="white">I pushed, hoping to isolate the short stack. I had to doubt SB had Jacks or better, and I figured Button was making a move with any decent hand that I had beat. I figured SB to have a smallish pair/worse ace or he'd have raised to isolate, so worst shot is coinflip, and I have him covered, and I figured I could still beat him heads up with a 3:1 disadvantage chip stack

Button had KQ, SB had TT, SB won the hand and won heads-up when his KJ beat my J3 on a J77 flop</font>
