|Repertoire themes is a common name for problem themes that are focused on movement possibilities of different chess pieces. These include:
(1) Knightwheel presents maximum ie. 8 knight moves for the solver. These moves may be part of the set play, virtual play (tries) or solution.Funnily enough the white knightwheel is usually called knight-tour, while black knight performs the knightwheel proper.
(2) Windmill includes the maximum of 13 bishop moves. Of course this is possible only,when the bishop originally stands on one of the central squares e4,d4,e5 or d5. (Note that the term "Windmill" or "Seesaw" is perhaps better known as a tactical repetitive device. The meaning is different from current context)
(3) Rook-cross displays the 14 rook moves.It is a rare theme.
(4) King-cross and king-star are two repertoire patterns for a king. The former consists of 2 horizontal and 2 vertical squares around the king, while in the star king moves 4 ways diagonally.
These king themes do not normally form essential content of a problem, but rather are regarded as artful additions.
(5) The lowly pawn has no less than 4 themes dedicated to it:
- Albino introduces all four initial white pawn moves.
- Pickaninny is the same theme for a black pawn
- AUW (Allumwandlung) shows all four possible promotions
- Excelsior happens whe a pawn goes from the initial square all the way up to promotion during the solution.
(A special mention should be also given to Babson Task, which includes two synchronous AUW's-white and black- an example submitted by papadoble, see #1573)
The tutorial puzzles on Repertoire theme are nos. 1580-1587, 1592 and 1593.
There are only three kinds of chessplayers - those who can count and those who cannot....
