AKs OOP

0.10/0.20NL 10 handed.

Villain is in his first orbit at the table. He has $20, I cover.

A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/diamond.gif[/img] in SB.

Three limpers. I raise to 1, MP calls.

Flop K [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] (pot 2.80)

I bet 2, Villain calls.

Turn 6 [img]/images/graemlins/spade.gif[/img] (pot 6.80)

I bet 6, Villain calls.

River 9 [img]/images/graemlins/diamond.gif[/img] (pot 18.80)

I push...

Is there a better line here (I know... raise more pf)? Should I bet smaller on the river, or check to induce a missed flush draw to bluff? Should I have slowed down at any point?
