well that was a great river 80/160

[HOWMANY]

4 handed live game, sb is very loose preflop, too aggressive with high hands on low boards and not aggressive enough with low hands and draws. bb is yosh nakano who I am told is very good at poker.

co folds, I raise button with A[img]/images/graemlins/diamond.gif[/img]4[img]/images/graemlins/diamond.gif[/img]8[img]/images/graemlins/diamond.gif[/img]K[img]/images/graemlins/club.gif[/img], sb and bb call.
