Chess
problems, mate search
This
allows you to solve chess problems (“White to play
and mate in n moves”). There is a special mate solving
engine which can also handle selfmates in which White must
force Black to mate him, and helpmates, in which both sides
co-operate to mate Black.
In the
dialog box for the mate search, select an engine (only
engines which are specialised for mate searches will be
displayed) and specify the kind of problem you are solving.
“Parameters”
allows you to set certain options, especially for very deep
mate problems which would otherwise take too long.
“Heuristic
search” allows you to specify the maximum number
of flight squares the black king can have.
“Threat
with check” specifies how deep a mate threat should
be for it to be considered.
The program
not only displays the key move of the problem, but also
generates a complete solution, with all alternative defences
by Black. If the problem has more than one solution (i.e.,
it is “cooked”), then alternate solutions will
be given as lines to the first move of White. “Last
move” specifies whether the last move of the problem,
which is usually obvious, should be included or not.
