First tries at 25-50

[AbelM]

5 handed 25-50 game on UB. One of my first sessions ever, so i don't know much about opponents. Villain (gandi9) seems solid so far though and i haven't been doing anything crazy either. Villain has 6800, i cover.

I'm in the BB with 66, UTG limps (has done this a few times) and SB(villain) raises to 200. We both call.

Flop is 9 [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/heart.gif[/img] 3[img]/images/graemlins/club.gif[/img]. Pot is 600.
SB bets 600, I call and UTG folds.

Preflop raise oop into two people seems very strong (overpair, overcards maybe even with hearts seem like good possibilities).

Turn is 9 [img]/images/graemlins/spade.gif[/img]. SB checks, i bet 1200, he calls.

Great spot to represent the 9, after his call though i'd think an overpair is very very likely for him.

River is 4 [img]/images/graemlins/club.gif[/img]. Pot is 4200 and he has 4800 behind. He checks to me. Good spot to bluff or give up?

Comments on other streets also welcome of course.
