score_all_moves.cpp

Evaluate every legal column from the current position and print one line per column: the column index and the perfect-play score that results from playing it.

Evaluate every legal column from the current position and print one line per column: the column index and the perfect-play score that results from playing it. Equivalent to what an analysis UI would do to surface candidate moves to a human.
