IntroductionThe main idea of this variant is that ordinal pieces may form complex pieces called hybrids.
The following rules describe all the differences between hybrids and orthodox variants:
- Queens are replaced by Guards ((0,1)- and (1,1)-leaper).
- Prime pieces (i.e. Rook, Bishop, Knight, Guard) are able to form so called hybrids. A prime piece A can move to a square occupied by some friendly prime piece B. As a result a new hybrid piece appears. The hybrid can move by the same way as A either B does. A hybrid may be also disjointed, any piece it consists of can move by itself.
- Only prime pieces (neither King nor Pawns) can form a hybrid.
- Equal pieces can also form a hybrid.
- No more than two prime pieces can form a hybrid.
- Pawns may be promoted into any prime piece. (It is forbidden to promote into a hybrid).
- Castling is forbidden.
NotesRules 1, 2.3, 4 are subjects to discuss. It may be interesting to cancel some of these restrictions and have sub-variants.
A project hybrids is dedicated to hybrids variant. Currently it contains only a chessboard (no engine) written on python. It is possible to play human vs. human only.
