The upper one is Snowie´s opening range UTG. The one on the bottom is Snowie´s defense range vs a MP 3B (either calling or 4b).

Snowie defends around 27,31% of its range against a pot sized raise. This means MP could 3B any two cards to profit.
Can somebody explain why that is? I thought Snowie is close to GTO preflop?
I tried to come up with some explanations myself, but couldn´t really come to a conclusion with which I could say: "that must be it".
