Shogchess

Introduction

Shogchess was invented by H. Ó. Kjartansson who likes to play shogi and chess. So he made a chess variants that combined these two games, it has the castling rule from chess and the starting setup, promotion rule and the drop rule from shogi (Therefor, all pieces are same color. Their direction tells which player it belongs to). All pieces used in shogchess are used as well in shogi or in chess; or in both; except for:

the Amazon (a promoted queen),

the Alifil or Elephant (which comes from xiangqi),

the Vazir

and the Camel

Setup

The game is played on a board 9x11 squeres.

Pieces

NOTE: All pieces are of the same colour. Only the direction of the pieces tells which player a piece belongs to. P=pawn. The pawn of shogchess move as in shogi, ie. one squere orthogonally and captures as it moves. They may step two spaces orthogonally without capturing on their very first turn. The pawn promotes to gold.

W=wazir. It is the first of four pieces that doesn't belong to shogi or to chess. It moves one squere orthogonally and captures as it moves. Promotes to gold.

E=elephant. Another piece that doesn't exist in shogi or chess. Moves exactly two squeres diagonally. Can jump over other pieces. Promotes to a bishop

C=camel. The third non-shogi non-chess piece. It is a (3,1) jumper and promotes to a knight.

N=knight. Moves exactly as in FIDE chess. Promotes to gold.

G=gold. Moves as a king but can't move diagonally backwards. Does not promote.

B=bishop. Moves as in chess. Promotes to a pegasus.

R=rook. Moves as in western chess and promotes to a dragon.

Q=queen. Moves as bishop or as rook. Promotes to an amazon.

K=king. The royal piece, if it gets captured, you lose. Moves as in chess.

PROMOTED-ONLY-PIECES

S=pegasus. Moves as king or as bishop. Note that the pegasus isn't royal.

D=dragon. Moves as king or as rook. Note that the dragon is not royal.

A=amazon. Moves as a queen or as a knight. Note that the amazon isn't royal.

Rules

1. The object of the game is to checkmate the opponent's king.

2. If a sequence of moves is repeated three times, the game is a draw.

3. PROMOTIONS:

a. A piece that moves into the opponent's start files (the last four files) may promote. A promotion is indicated by flipping over the piece.

b. Promoted pieces lose their promotion when captured.

4. DROPS:

a. A captured piece may be dropped onto the board (placed on a vacant squere) to subsequently be used as one's own. This is done in lieu of a regular move.

b. A pawn may not be dropped onto a file that contains one of yours un-promoted pawns.

c. A pawn may not be dropped on the two ranks under their starting rank, i.e. a white pawn may not be dropped on ranks one and two and a black one may not be dropped on ranks ten and eleven

d. No piece may be dropped onto a squere from which it is impossible to move.

5. Castling is as follows: 0-A (Ke1-c1 Ra1-d1), (Ke11-c11 Ra11-d11) 0-I (Ke1-g1 Ri1-f1), (Ke11-g11 Ri11-f11)

6. Pawns may move one or two squeres on their very first turn. A pawn dropped on it's starting file is seen as not moved, so it may take two steps.

7. There is no "en-passant".

8. You cannot mate by dropping a pawn.

9. Stalemate is draw.
