[Paul2432]

This hand occurred in a Party $200+15 STT.

Party Poker No-Limit Hold'em Tourney, Big Blind is t100 (6 handed) converter

Button (t1060)
SB (t555)
Hero (t1420)
UTG (t1865)
MP (t2745)
CO (t2355)

Preflop: Hero is BB with A[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/heart.gif[/img].
<font color="#666666">3 folds</font>, <font color="#CC3333">Button raises to t450</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero ??</font>

Up to this point I don't recall the button doing anything unusual. I have been playing fairly aggressively.
