UTG calls t150, <font color="#666666">3 folds</font>, MP3 calls t150, <font color="#666666">3 folds</font>, Hero checks.

Flop: (t525) 9[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/club.gif[/img], 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets t400</font>, UTG raises to t1200, MP3 folds, Hero ??

800 for me to call into 2100, if i push it would be for like 5k more

nothing special, but he seems decent, does play hands fairly fast (raised strong with top set on the flop)
