I don't have a comment on the hand other than that guy was a clown to call your river raise.

With only 3 people in the hand, I think I have to call, but I think a raise to $10 would've been more effective depending on the player. If the SB tends to make a lot of small bets and he's betting this low, he's gonna keep betting low and implied odds make it a good call for you if he has a Jack, TT, or nothing.

I'd have to ask myself, "Does he make this tester bet with 88, 66, and AQ?" If that's a yes, I'll raise. If that's a yes, but he won't laydown a weak Jack, 66, or AQ here, he won't lay down when you come over the top if you hit your 9 and he has a Jack or TT in the hole.

In full ring or even 7 handed, this is an automatic fold for me, but 3 handed is a different story.
