Well it isn't my worst but certainly most recent

Playing a forum tourney other night with 4 players left and I am chip leader (pays 3) Blinds high and lead is changing hands like crazy.
SS pushes all-in UTG SB calls and I look down at QQ. I just call because SB is very close to me in chips. Flop comes down K-Q-2, what a great flop. SB checks and I am not chancing letting SB catch up with a str8 or flush so I bet.
SB folds and short stack flips up A-9, oh how sweet it is

until turn 10 river J


I go from 1st to last and fighting for my live to cash.
Eventually I finish third when SB goes for a steal with 9-5 and I call with 4-4 and he makes a str8 lol. A-9 eventually wins the game.
Damm poker, what a silly game.
