2/4 Absolute, QJo in the SB

[Somekid]

BB is 24/16/2.2 through 240 hands
Villain in the CO appears to be a bit LAGgy, but I don't really have a read.
I have QJo in the SB

PF: Villian limps in CO, I complete, BB checks.
Flop: 9c 8c Jd (3SBs)
I bet, BB raises, CO calls, I call
I'm not really sure what to make of the raise, I figure he has a jack too and I just want to see a showdown.

Turn: 4s (4.5BBs)
I check, BB checks, CO bets
I raise, BB folds, CO calls.

I figured that the CO could be betting with anything and the BB was on some sort of draw or a light raise to force the CO out. I wanted to force out the BB with a c/r and then see a showdown against the CO.

River: Ks (8BBs)
I bet, CO calls.

eh eh?
