Perhaps "positional" test positions, in test suites, should give several
solutions with some solutions given more points than others.  I vaguely recall a
chess book titled something like "Point Count Chess."  The author gave the
reader the most points for finding the best move, but also awarded  a few points
for lesser solutions.

Maybe that should apply to chess engines too.  An engine that doesn't
necessarily always find the very best move may still be able to play a decent
game of positional chess.  Test suites aimed at measuring a chess engine's
prowess at positional chess perhaps should be multi-solution.
