# King and Queen

Introduction
This is a game I created for the 39-square chess variant design contest. It is a fairly simple game with a unique board layout. The goal of the game is to checkmate the other player's king or queen.
Board
The board has a total of 39 squares: two row of three squares, then three rows of nine squares, then another two rows of three squares, shown as follows:

P = pawns, N = knight, B = bishop, C = cannon, K = king, Q = queen.
One player is the Queen (blue) and the other is the King (red). The blue and red colored squares represent the respective color's castle. The King and Queen cannot go out of his or her castle.

Pieces
There are five different types of pieces, each has a general and specific name for each side (red and blue). To accommodate for promotions and dropping, it is best to use flat pieces that can be flipped, and also pointing like an arrow. An example is a Shogi playing piece, with one side denoting the regular piece and the other side the promoted piece.

Pawns move one square forward. Promoted pawns move any number of squares horizontally or vertically.

Bishops move one square diagonally. Promoted bishops move any number of squares diagonally.

Knights move one square horizontally or vertically, then one square diagonally, like a knight in XiangQi, which means it can't 'jump'. Promoted knights can 'jump' as in orthodox chess.

Cannons move any number of squares horizontally or vertically, but capture over another piece, like a cannon in XiangQi. Promoted cannons can move diagonally.

King and Queen move one square horizontally or vertically within the castle. Promoted king and queen can move one square in any direction within the castle.

Promotions
Promotions are rewarded upon capture of an opponent's piece. Each side has a unique name for each piece and its promotion.

The Queen's Side
(pawn) Amazons are promoted to Valkyries.
(bishop) Shamans are promoted to Druids.
(knight) Riders are promoted to Pegasi.
(cannon) Spearmen are promoted to Archers.
(queen) Queen to Empress.

The King's Side
(pawn) Soldiers are promoted to Veterans.
(bishop) Bishops are promoted to Saints.
(knight) Knights are promoted to Dragons.
(cannon) Catapults are promoted to Cannons.
(king) King to Emperor.

Dropping
Upon capturing an opponent's piece, you can drop that piece back on the board. There are several rules on dropping:
You cannot drop on the same turn you capture.
You cannot drop if you dropped last turn.
You can drop only one piece per turn.
You can only drop on an empty square of your castle.
Dropped pieces are in their unpromoted state.
Rules
There are a few additional rules to the game:
The player on the Queen's side goes first.
The King or Queen cannot move into a square which puts it into check.
Upon check, the player must move out of a check; if the player fails to do that, he/she loses. Also called checkmate.
If a player's only move is into a check, that player loses. Also called stalemate.
As in XiangQi, a king or queen cannot move into a vertical rank as the opponent's king or queen if there are no pieces in between.
Notes
Most of the inspiration for this game is from XiangQi, or Chinese Chess, including the castle, different names for each side, the cannon, the 'checking' rule for king and queen with no pieces in between, etc. Other inspirations come from other types of chess, including regular chess, shogi, etc.
