From the Sigma Chess Lite (Macintosh freeware from www.sigmachess.com) manual: The Mate Finder Levels Sigma Chess uses a specialized search algorithm for solving mate problems. First you specify the (maximum) number of moves to mate, and then you invoke the mate finder via the Go command. If no mate is found, a dialog appears stating this. If a mate is found, you will be given the option of either canceling the mate search, continuing the search for alternative solutions (called cooks) or accepting the solution. If you accept the solution, Sigma Chess will play the move (called the key) and decrease the mate level by one. This way you can play through the mate sequence move by move. -Richard A.
