I really think you need to forget about the bubble, and play your game.The reason is: You are pretty sure you got him beat, which you will have many many times with QQ here.and if that´s correct you will have about 20k in chips and a really decent chance to take the rest of he´s chips and win the tournament.If you lose... well it´s poker right, you had your money in the right spot.I am not a pro though, but that´s what i would do.
