Party 3/6 6 max: K9s on the button

I call rather than re-raise this player on the river. You run into A9 or TJ a fair amount of the time given this guy's profile.

Perfect. You got just the right number of bets in. True, his river 3-bet means you're probably screwed, but you are still right to raise it. You have a monster and SH people are weird. I'm a fan of slowing down sooner rather than later (usually to ensure a SD), but here your play is raise the river. When he just calls and shows a Q and it turned out he just wanted a bet in every street, you'll be glad.
