River Decision?

[James.]

6handed.

first orbit, maybe second. BB seems sort of loose and passive. UTG raised earlier with AJo and bet it UI the whole way. lost to A6o that flopped a 6. that's all i know(it was BB in that hand that he lost to).

anyway, UTG raises, i 3bet A [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/heart.gif[/img] in the CO(comments?), folds to BB who calls, UTG caps, we call.

Flop(12.5sb): K [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/heart.gif[/img]

BB checks, UTG checks, i bet(comments?), BB calls, UTG calls.

Turn(7.75bb): 7 [img]/images/graemlins/club.gif[/img]

check, check, i check(comments?).

River(7.75bb): A [img]/images/graemlins/club.gif[/img]

check, check, and it's on me...

what about how i've played the hand to this point? why are we doing what on the river?
