AK on the satellite bubble

[bulldog999]

Situation:
-4-handed and 3 seats go the the Full Tilt 100 WSOP Seats Guaranteed tourney
-dude1 has knocked me down from 8,000 chips by coming over the top of me all the time for all my stack
-squeezer is playing zero hands waiting for me to bust out
-I haven't tangled with dude2, he's playing pretty solid
-4th pays $267 (buy-in was $75)


(couldn't find a hand converter for Full Tilt?)
