The fair leaf evaluator
The hand-written board evaluator every search in this family uses at the bottom of its look-ahead, and the tuning bench its coefficients came from.

Each page here is one theory of how to choose a column, grouped by the technique it uses; the engines that play the games and the instruments that measure them live under Engines and Diagnostics.
Fair expectimax
Look a few moves ahead, take the best column on your own turns, and average over every sampled disc the game might deal.
Hand-built heuristics and shallow search
Scores visible board traits, adds them together, and plays the highest-valued column.
No approach page matches that search.
