Bovada NL200 6 Max. 

CO is likely a recreational player. Only has $140 to start the hand. Anonymous tables so no reads on villain. The river is set up for slightly small than pot size shove. Is this river an easy shove or thoughts on how this hand should be played differently. 

Hero raises $6 w. Kc Kd. CO calls, Btn folds, SB calls, BB folds. 

Flop (Pot: $20): Qs Jc 9s. SB checks, Hero bets $14.00, CO calls, SB folds. 

Turn (Pot: $48): 9h. Hero bets $30. CO Calls. 

River (Pot: $108): 6d Hero?
