Hi guys. I was looking through some preflop spots in Monker Solver and came across something I wanted to understand a little more and maybe there is a leak in my thought process. Here is Monker Solver's fold KK % in BB vs (excluding KKK and KKKK)

CO raise, btn folds, SB folds, BB folds KK 0%
CO raise, btn calls, SB folds, BB folds KK 0%
CO raise, btn calls, SB calls, BB folds KK 12.9%

My guess seeing this is that still 3-way when you have a K flush blocker on a 3 flush card flop/turn, you win more EV 3-way in those spots being able to get folds, but 4-way, your forced to play a little more straight forward. Maybe same goes for boards like QJT or QJ9, maybe your able to capitalize some more EV bluffing 3-way or HU, but you have to play straight forward 4-way or more. Also, I'm guessing that when the money goes in 4-way, your less likely to be in good shape? This is assuming optimal players I'm guessing from monker, but I'm guessing you can defend any KK multi-way in the BB with fish involved. But what is interesting is that Monker is still folding hands like KK92, Kss at a 52% frequency even though you have a K high suit.

What do you guys think about this? Can any of yal elaborate on more reasons for this? I want to understand the profitability of pairs the most in situations like this because I feel like that is a big part of Live PLO and even if it is a limped pot in PLO and not much raising, I want to better understand if I should be folding hands like KK92:Kss preflop from MP or EP depending on the tables.
