First-turn measures

All four describe THECA 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.

5.02 Entropy (bits)
147 Avg remaining
0.0% Exact match
93.8% Avg ruled out
Higher first-turn entropy than about 84% of evaluated openers
