Three-handed, blinds 0.5 and 1, no ante, winner takes all, at 25, 15 and 10 big blinds. The preflop equilibrium is solved with CFR over the 169 starting hands. Pots that go to a flop are valued by a separate postflop solver instead of raw equity, and the two are iterated until the ranges stop moving; three-way flat pots are the one place still approximated.

Grades follow the EV you gave up versus the best action: Best, Good, Inaccuracy, Mistake, Blunder. A mixed action counts as Best.
