40/80 river

commerce 40
i have been in the game for maybe 40 minutes, and have done nothing of note. the button in this hand is young and looks familiar to me. i think i recognize him from bellagio, but i'm not sure. in any event, for some reason i get the impression he is not horrible.

folds to button who opens. i call in the bb with K [img]/images/graemlins/spade.gif[/img]3 [img]/images/graemlins/spade.gif[/img]. flop QJ3 with 2 [img]/images/graemlins/diamond.gif[/img]s

i check/call.

river: 9 [img]/images/graemlins/diamond.gif[/img]

i do what?
