Patchanka
DESIGN ON-GOING, NOT READY FOR PUBLICATION This game ambitions to involve several pieces that are not used in the other variants from the author. Most of the pieces are "bi-compounds" of other more familiar pieces. There are the three possible associations of the oblique leapers, Knight (2,1), Camel (3,1) and Giraffe/Zaraffa (3,2). There are also the Japanese Kirin and Phoenix, compounds of the basic atoms Wazir, Ferz, Alfil, Dabbaba. Finally, the newest pieces are the slider/leaper compounds combining Rook with Alfil, and Bishop with Dabbaba. These two later pieces can be seen as the extension of the Kirin and Phoenix and, so logically, one may promote to the other one. Indeed, using Betza's notation FD (Kirin) promotes to FFD=BD (Badger) and WA (Phoenix) promotes to WWA=RA (Ram). The strongest piece does not start on the initial array. It is a mighty oriental queen, the Begum which has augmented power from its standard counterpart, and which is appearing only by promotion of a Pawn or a Soldier. The Soldier is an augmented Pawn which has been experimented with success in other variants. It is an efficient support of the front line of Pawns.Setup
Pieces
King: moves 1 step in any of the 8 orthogonal or diagonal directions to an unattacked square. The King is in check if it is attacked by one or several enemy pieces. It is forbidden to play a move leaving one's King in check. The only difference with standard chess is that there is no castling in Patchanka.
Pawn: can move, without capturing, straight forward one square or two squares from its starting position if the interving square is empty. It captures one square diagonally forward. It may also capture and be captured "en-passant" (see below). Almost identical to standard chess, the only difference is related to its promotion (see below).
Soldier: is an "augmented Pawn". It captures 1-square diagonally forward like a Pawn, but moves with no capture either 1-square forward or sideways (left or right). It may also step two empty squares forward from any position on the board. Otherwise, it is identical to the Pawn (same promotion, en-passant capture rules). The soldier is also found in Zanzibar-Maasai Chess and in Bigorra. Betza's notation: fsmWfceFfmnnD
Wildebeest: combines the leaps of the Knight (2,1) and the Camel (3,1). Betza's notation: NC
Okapi: combines the leaps of the Knight (2,1) and the Giraffe (from Grant Acedrex = Zebra) (3,2). Betza's notation: NZ
Bison: combines the leaps of the Camel (3,1) and the Giraffe (from Grant Acedrex = Zebra) (3,2). Betza's notation: CZ
Kirin: combines the steps of the Ferz (1,1) and the leaps of the Dabbaba (2,0). This piece is from Chu Shogi. Betza's notation: FD. In Patchanka, the Kirin may promote (see below).
Phoenix: combines the steps of the Wazir (1,0) and the leaps of the Alfil (2,2). This piece is from Chu Shogi. Betza's notation: WA. In Patchanka, the Phoenix may promote (see below).
Badger: rides diagonally as a chess Bishop or leaps as a Dabbaba (2,0). Betza's notation: BD, hence its name BaDger.
Ram: rides orthogonally as a chess Rook or leaps as an Alfil (2,2). Betza's notation: RA, hence its name RAm.
Begum: mighty piece that combines the powers of the Badger and the Ram. In other words, it combines the moves of the chess Queen and the leaps of the Alfil and the Dabbaba. Betza's notation: QAD. This piece is not present on the initial array, it appears through promotion of Pawns or Soldiers only.
See the Interactive Diagram above and its facilities to illustrate the different moves.
Rules
Several classical chess rules apply here. This includes Pawn's en passant capture, Pawn's initial double step, Pawn's promotion on the last rank at the opposed side of the board (rank 10 for White, rank 1 for Black).
The only difference is that the Pawn may promote to a Begum (of the opposing color) and nothing else.
Several pieces can get a promotion at Patchanka when reaching the last rank of the board. Promotion is immediate, compulsory and cannot be refused.
- A Pawn is promoted to a Begum
- A Soldier is promoted to a Begum
- A Kirin is promoted to a Badger
- A Phoenix is promoted to a Ram
En Passant capture: Any time a Pawn or a Soldier takes a double step and passes through the capture square of an opposing Pawn or Soldier, that Pawn or Soldier may capture the Pawn or Soldier as if it had only moved one square. This en passant capture must be made in the move immediately following the double step. Only a Pawn or a Soldier may capture en passant.
End Of Game: The end-of-game rules, checkmate, stalemate, etc., are identical to standard chess.
Notes
This game has been inspired by Compound Chess proposed by Kevin Pacey where the pieces equivalent to Begum, Badger and Ram are employed, though they were not named as such.
