Mate Score
Mate Score: An engine announcement that forced checkmate exists in a specific number of moves.
In-Depth Explanation
A display such as M5 means the engine has found mate in five moves against best defense. A negative mate score means the side being evaluated is getting mated. Mate distance can change as search deepens, so follow the principal variation and verify the first forcing move.
