Gto wizard seem bad

The free exercises are curated spots, not random deal simulation, so you're going to see ranges that make the decision non-trivial. In SB vs BB all-in spots the BB equilibrium calling range is typically around 65% of hands, which skews toward decent holdings by definition. It feels rigged but that's just what a balanced calling range looks like when someone is defending correctly. If you want to see random runouts, you need actual hand history review rather than preset exercise nodes.
