SB called 2 bets cold with KJo, and was 66/8/0.77--of course, over the 230 hands I have him on in my DB, he's winning at 14.96BB/100...I have no idea why I capped the river. Maybe I was in denial that this guy called me getting 4.5-to-1 on a gutshot draw. Lesson--never slowplay a set against a donkey.

I have no problem going for the check-raise there, as long as MP2 has decent aggression. Usually I'll lead into him, but you've got to mix it up every once in awhile.

Even if you bet it, youd have lost the hand. If the guy is going to call for the river gutshot in a pot that miniscule, he is going to peel on off with his overcards on the flop, then pickup the gutshot draw and get there.

That said, i also dont beleive in slow playing flopped sets, unless you are pretty sure someone else will do the betting, like if theres a PF raiser on a flop of like KQ6 and you have 66 or something like that.
(Man thats always fun though, isnt it?)
