Weird huge pot QQ hand

[Justin A]

Party 15/30. This is the very first hand of my session but I have stats on the important players, not sure if the stats matter too much here.

Party Poker (7 handed) converter

Preflop: Hero is BB with Q[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/club.gif[/img].
UTG limps, UTG+1 raises, CO and button both cold call, SB folds, I 3bet, everyone calls to the CO who caps, everyone calls.

CO is 25/10/1.7 Button is 37/3/0.6
