PP 10/20

6 folds and I raise on the button w/ A [img]/images/graemlins/club.gif[/img]4 [img]/images/graemlins/heart.gif[/img]. only the BB calls. BB is pretty much non-descript, say 28/14/1.3

A [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/club.gif[/img]
he checks, bet, calls

K [img]/images/graemlins/spade.gif[/img]
he checks, I do likewise

Q [img]/images/graemlins/spade.gif[/img]
be bets, I call

What say you and why?

I use this line frequently. I am getting to the point where I think I need to raise the river at certain times for value but have yet to solidify my thoughts on the criteria to use in order to make this play work. Any help for me here?
