How much action on the river?

[sfer]

10 handed Party 20/40. My first hand and I post in the CO. Folded to the hijack who raises. He has solid stats (16/10/1.7) but I don't remember him so I don't know how he plays postflop. I 3-bet with 99, SB calls, hijack calls. 3 players, 10 SBs.

Flop is Q [img]/images/graemlins/club.gif[/img] 9 [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/heart.gif[/img]. I don't have a [img]/images/graemlins/club.gif[/img]. SB checks, hijack bets, I raise, SB check/3-bets, hijack caps, I call, SB calls.

2 players, 11 BBs. Turn is another Q. SB bets, hijack raises, I 3-bet, SB folds, hijack 4-bets, I call.

River is an A, not a [img]/images/graemlins/club.gif[/img]. Hijack bets. How many bets am I going here?
