You'll notice a set of VCR buttons below the variation board; these are your controls
for playing through moves on this board.
You can step forward and backward through the variation one move at a time by using
the single arrow VCR buttons.
If you want to jump right to the beginning or end of a variation, you can use the
double arrow buttons for that purpose.

3.5.13 Chess problems, mate search
Hom e - Le v e ls

M a t e se a rc h (or Ct lr-M )

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
