Button (t30375)
Hero (t68710)
BB (t73790)
UTG (t56816)
UTG+1 (t13539)

Preflop: Hero is SB with T[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img].
<font color="#666666">5 folds</font>, <font color="#CC3333">Button raises to t4000</font>, Hero calls t3000, <font color="#CC3333">BB raises to t12000</font>, Button calls t8000, Hero Call or fold?

Button is fairly new at the table &amp; BB pretty tight, not wild at all.
