Hand vs. Fsuplayer

[ObnxNole]

Live $3/5 home game. The game is 5 handed. Fsuplayer is playing very LAG. He's won some big pots during the night, running hot as hell, and has already cracked my top set once earlier in the night.

Hero($1600) dealt 6 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/club.gif[/img] on the button. One limper and I raise $20 straight.
Fsuplayer($2000) calls in the big blind. Limper calls and it's 3 to the flop.

Flop: 9 [img]/images/graemlins/spade.gif[/img]6 [img]/images/graemlins/spade.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img]

2. Call/Fold the river?
