Always using the "Chessmaster" checkbox of the "Thinking Lines" window (and the
Infinite time control -- although this is not strictly necessary). This way of
doing it will find most forced mates very quickly.

However, VERY tricky mates can be found faster using the "Solve for Mate" mode,
which basically does a brute force search with no extensions (similar to Chest
and other mate-solving programs). This is guaranteed success if a mate exists
(within the number of moves specified by the user), but it will almost always
take much longer than the first method.
