Results:

Hero showed K[img]/images/graemlins/heart.gif[/img] K[img]/images/graemlins/diamond.gif[/img]

Button somehow loses with two face cards
SB loses with the best possible hand
Hero wins $93.30 with Kings full of Nines

What I like about this hand
<ul type="square">[*] SB failed to raise with AA.[*] Button traps for his last $0.60 just to make sure he doesn't miss out on anything 59-cent McD's cheeseburger night has to offer.[*] I minbet $1 into a pot of $92.10 so the guy who's coaching me doesn't ask why I didn't c-bet.[*] nice one-outer[*] No one even has a flush redraw just to get their hopes crushed when the spade hits but pairs the board.[/list]
