First-turn measures

All four describe ARCUS used as an opening guess. Entropy is the same idea as “avg ruled out” on a log scale: a higher number means the guess splits the possible answers into more, smaller groups.

4.90 Entropy (bits)
133 Avg remaining
0.0% Exact match
94.4% Avg ruled out
Higher first-turn entropy than about 78% of evaluated openers
