Both HRC and ICMizer use Nash ranges for default opponent ranges. SNG Wiz apparently uses some proprietary method to come up with opponent ranges.
Sometimes Wiz ranges can be just terribly unrealistic, as in the default BTN reshove range when we fold in the OP. I find Nash ranges to be way off in many situations, at least in the micro games I play, as these ranges have opponents pushing and calling much wider than they actually do in game. So, for hands that you study closely, you need to manually set opponent ranges according to typical play that you see in your games or particular reads on individual players. And you need to do this at
all points in the game tree, which includes opponent actions that occur
after you fold, as in the case with setting the BTN reshove range when we fold for the hand in the OP.
