Trying to incude a bluff ($55)

[AliasMrJones]

Over the past couple of days I've been experimenting with checking the river when I have a good hand and a pseudo-scary card hits with the intention of calling any bet. This is along the lines of if I bet and they have nothing they will fold and I win nothing, but if they actually hit it, they get to take all my money, but if I give them a chance to bluff, I sometimes get to take more money from them. Unfortunately, I have been using it as more of a general strategy on the river, rather than really looking for places that villain might or might not call a straight river bet. Anyway, on to the action.

Villain was somewhat loose and somewhat aggressive preflop and had been a little tricky (check-raise flop) postflop.

Preflop: AliasMrJones is BB with 8[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/club.gif[/img].
<font color="#666666">5 folds</font>, <font color="#CC3333">CO raises to t60</font>, Button calls t60, <font color="#666666">1 fold</font>, AliasMrJones calls t30.

Flop: (t195) A[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
AliasMrJones checks, CO checks, Button checks.

Tried for check-raise, but it didn't work...

Turn: (t195) 5[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">AliasMrJones bets t120</font>, CO folds, Button calls t120.

...So I bet out the turn.

AliasMrJones checks, button goes all-in(610), AliasMrJones calls.

I thought an A or flush draw was more likely than a 5.
