Preflop: Hero is Button with 2[img]/images/graemlins/spade.gif[/img], 2[img]/images/graemlins/heart.gif[/img].
UTG calls, <font color="CC3333">MP raises</font>, CO calls, Hero ???

Interested in hearing comments about the play here. This was about my ninth hand at the table, and I've only recently begun playing 10/20 so did not have notes or good reads on any of them. Table had been passive up to this hand and had not seen much pre-flop raising.
