UTG+1: $93.00
MP1: $604.70
MP2: $157.50
CO: $20.00

Pre-flop: (8 players) Hero is Button with T[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/club.gif[/img] 9[img]/images/graemlins/heart.gif[/img]
UTG calls, UTG+1 calls, 2 folds, CO (poster) checks, <font color="#cc0000">Hero raises to $10</font>, SB calls, BB folds, UTG calls, UTG+1 calls, <font color="#cc0000">CO raises all-in $18</font>, Hero...

Presumably raising this versus 2 limpers and a poster on the button is standard.

Shorstack poster shoves (clearly has nothing, but it's re-opened the betting) - should I re-pot it (to $92 total) here with these stacks, just call and see a flop, or make a smaller re-raise?

The other guys in the hand have 112, 188, and 83 behind and I cover.
