98s, plan for the river

[Wad]

Pretty loose table, PokerTracker says I have 42 hands with the SB (VPIP 42.2, PFR 2.22) and 22 hands with CO (VPIP 72.7, PFR 4.55)

Party Poker 1/2 Hold'em (8 handed)

Preflop: Hero is UTG+1 with 9[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/club.gif[/img].
UTG folds, Hero calls, MP1 folds, MP2 folds, CO calls, Button folds, <font color="CC3333">SB raises</font>, BB folds, Hero calls, CO calls.

Flop: (7 SB) Q[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/spade.gif[/img] <font color="blue">(2 players)</font>
<font color="CC3333">SB bets</font>, <font color="CC3333">Hero raises</font>, CO calls, SB calls.

Turn: (6.50 BB) 5[img]/images/graemlins/heart.gif[/img] <font color="blue">(2 players)</font>
SB checks, <font color="CC3333">Hero bets</font>, CO calls, SB calls.

What's the river plan?
