Valuebet?

[Yossalah]

So villian(SB) here is unknown, he just bought in for 200bb. I am not feeling confident about my game at all. I am a fairly aggressive player who raises a lot, but I haven't even remotely hit a flop in like an hour.

Thoughts about the hand, especially if a bet on the river of any size is a good idea.

.5/.10
5 handed

Hero has $43 and covers villain
Hero is dealt A[img]/images/graemlins/heart.gif[/img] 5[img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/heart.gif[/img] OTB

Preflop:
Everyone limps, SB completes, BB checks

Flop: $.50

SB bets $.40, BB folds, UTG calls, CO calls, I call by accident (computer was running slow),

Turn: $2.00

Checked to hero who bets $1.90, SB calls rest fold

River: $5.75
