yea 66=Kx in terms of that our hand is a bluffcatcher (even though Kx is better since it has blocker to stronger Kx/2pairs), but Kx is in top of what we can have in this spot, so maybe we should balance our bluffcathing strategy by always calling with certain top part of our bluffcatchers?

plus Kx beat random merged balanced vbets if villian is any good
