Opponent is relatively new to me, on vacation for last month. very, very aggro preflop, flop and turn, slows down on river, not as loose as you'd expect for his level of aggresion. His PT #'s are 14/22 in full ring games with flop/turn aggression #'s 7.5/555 for sample i have of him.

Flop: ($150) T[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/diamond.gif[/img], 4[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">MP2 bets $147</font>, Hero calls $147.
