($6): QQ bubble v. all-in

[Pokey]

Four people left in the tournament, with me as the second-shortest stack and UTG. Set-up:

Pokey t1450 UTG
Button t2670
SB t325
BB t3555

Blinds are t50 and t100.
Pokey gets Q [img]/images/graemlins/club.gif[/img] Q [img]/images/graemlins/heart.gif[/img], raises to t325.
Button folds, SB folds.
BB reraises all-in.

BB started tourney tight and passive but became gradually looser and more aggressive as things progressed. By this point, he was playing 30% of his hands and raising with 10% of them.

So: easy call, easy fold, or tough choice?
