I don't know how I got brought into this, but I check the turn and fold the river.

is there a bet size on the river that you would call to pick off a bluff / thin value bet with a pair < KK? obviously for a min-bet you'd call right? 1/2 pot? 3/4?

what heuristic do you use to determine hand strength at each step in a line such as the above?
