I'm sure you'd call a player like phil laak passive too. It's not like he wont ever bluff.
We have
nut blocker so this cuts down alot of a nits value combos. Nits wont raise a 9high flush on this river vs a psb. So it leaves him with Kxcc/Jxcc which there are only Kjcc/K9cc(maybe if he peels pre) and J9cc/j8cc(maybe again) all combos which may raise flop or bet turn when checked to.
Hands we beat? We almost have the perfect bluff catcher in this spot, we have
, dont have to worry about pairs, since people dont snap raise a pair otr as a bluff, they atleast think about calling first. We beat J9hh j9ss j9dd, KJ maybe all combos, AJ all combos. Which is way more than his value range.
