AK against calling station

[IPSC]

I have 46 hands on UTG-1. (23.91 VPIP/2.17 PFR/0.36 AF)

Villian is rated as a semi-loose passive/passive.

Party Poker 0.5/1 Hold'em (8 handed)

Preflop: Hero is SB with K/images/graemlins/club.gif, A/images/graemlins/heart.gif.
<font color="#666666">1 fold</font>, UTG+1 calls, <font color="#666666">1 fold</font>, MP2 calls, <font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises</font>, <font color="#666666">1 fold</font>, UTG+1 calls, MP2 calls.

Flop: (7 SB) 8/images/graemlins/diamond.gif, 6/images/graemlins/heart.gif, 5/images/graemlins/spade.gif <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, UTG+1 calls, MP2 folds.

I bet the flop since I have a decent size pot, few opponents, and I have no reason to think my overcards still aren't good.

Turn: (4.50 BB) T/images/graemlins/spade.gif <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">UTG+1 bets</font>, Hero calls.

I checked because I wanted to invest the absolute minimum to see a showdown. I figured that check/calling two streets costs at most 2BB and betting the turn/river costs at least 2BB. I'm not giving myself any fold equity against this passive villian.

River: (6.50 BB) J/images/graemlins/heart.gif <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">UTG+1 bets</font>, Hero calls.

Final Pot: 8.50 BB

Is this weak? I paid 2 BB after the flop for a chance to win 6.50 BB. Am I winning this 30% of the time?

Thanks!

villian is passive, villian is betting against a PF raiser that checks on the turn, villian must have hero's high card beat.

He is passive, but what if my check is giving him the courage to bluff?

Passive is the key... Unless you see him bluffing lots you gotta put him on a pair, he won't bluff all the time...

Here id either check/fold or raise...

I think I would fold this river. You are behind here most of the time and only drawing to 6 outs.

[/ QUOTE ]passive people only bet when they have the goods. I would be surprised if he was bluffing.

probably should check/call turn and check/fold unless you get your A or K. If so I would probably check/raise but just calla 3bet because villian could have a nine for a straight and we're already drawing dead.
