another value bet with a weak hand question

[toby]

Party 1/2 6-max, 6 handed.

Hero is BB with 86o.

Folds to SB who completes. (I thought he was average at the time of this hand, after a few more orbits I then thought he was loose/passive and called with 3rd pairs and K high (on A high board) several times)

Flop: A [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/heart.gif[/img]
SB checks, Hero bets, SB calls

Turn: 6 [img]/images/graemlins/spade.gif[/img]
SB checks, Hero bets, SB calls

River: J [img]/images/graemlins/club.gif[/img]
SB checks, Hero...

Pros of betting-no flush draw came, I can beat a pair of 2's or 3's
Cons-86o is not a very strong hand, a passive player could have A4o or A5o

I bet. I don't think even passive players will have an A here. He'll call with 44, 55, 2 and 3...good enough for me.
