so the math is wrong cos i fucked up the combos of offsuit kings (really dont know how i did that). Ill blame that on 'ive been out of the game for a while'. But that leaves us in a better spot not worse. Villains range on the river is much more heavily weighted towards non Kx given that the river blocks a tonne of combos. Ill have to redo the maths when i get home.
I do use equilab but i did this work in a note pad.
