"Swedish Draughts" takes aspects of Spanish checkers and combines with
Frisian draughts. Orthogonal capture is deferred--neither Man nor Dame
can make an immediate orthogonal capture. They may, however, capture
orthogonally subsequently; as part of a capture sequence. A Windows
program is provided.
This is similar to traditional Swedish draughts (Markvärn), which is not
played anymore. The essential difference is that deferred capture has
been introduced.
