Happened in an AP tourney.
Me-SB with Q [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/heart.gif[/img]
Villain-A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/diamond.gif[/img]

Action doesn't get raised for some reason pre flop, so I call the blind and BB checks.
Flop is K [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/heart.gif[/img]
I check, MP bets, villain raises all in, I quickly call all in, everyone else folds.
Turn: K [img]/images/graemlins/spade.gif[/img] River :A [img]/images/graemlins/club.gif[/img]

I could do nothing as my 97% to win evaporates and my tourney hopes are gone. It was still early on so I needed chips and was going against the table chip leader. Worst beat to date for me.
