// each chess puzzle consists of up to 8 lines:
//
// up to three lines starting with tag [D] (puzzle description)
// up to four lines starting with tag [S] (puzzle solution)
// a FEN position description (see tools/readme.txt for format)
//
// Description and solution lines are limited to 32 characters not counting
// the tag ([D] or [S] on the beginning).
//
// Comment lines have to start with '//' or with '#'. Empty lines are allowed.
// The side to move is part of the FEN position description. There is no need
// to add this information to the puzzle description, too.
