AKs - simple river (eh, and all streets) question

[Ojo_Rojo]

Villain is pretty bad - 57/12 but is not particularly crazy. He loves draws, Ive lost a few pots to him as hes catching them regularly.

All comments appreciated... sorry if its too basic, but mainly I would like to know if you all would call this river. If not, then I may have exposed a leak [img]/images/graemlins/smile.gif[/img].

Edit: Would you pot this flop despite it being rainbow? I took the free card on the turn because I wasnt happy with what came up.

The game is Crypto, 200NL 6-max

Villains stack: $150 (MP)
My stack: $209 (MP+1)

UTG limps, Villain limps, I make it $9 with AK [img]/images/graemlins/spade.gif[/img]
UTG calls, as does villain.

Flop: ($30) K [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/spade.gif[/img]
Checks to me, I bet $18, only villain calls.

Turn: ($66) Q [img]/images/graemlins/spade.gif[/img]
I check behind.

River is a rag. Villain bets $30. Me??

Thanks, and seasonal greetings!!
