Pocket Shogi Copper

Introduction

In 2017, I did a Google search and discovered a web site that is designed to play Chess Variants. Not only does this web site allow for playing chess variants, it allows for programming of the chess variants. At that time, the most popular variant was a game called Shogi. It is Japanese Chess. I consider myself a beginner chess player, and a very new beginner at Shogi.

In my opinion, the game of Shogi is brilliant, there is a beauty to the game that any chess player can feel after playing a few games. As a beginner, I lack several skills to play a good game of Shogi. Once the Gold General is on rank #9, it loses a lot of its abilities, and I wanted the ability to pull the Gold General off the board and put him back in reserve. Based on other chess variants I came up with the idea of a pocket, where you could pull off one Shogi piece on the board and put it in a pocket. On your next turn, you could drop the Shogi piece using the standard Shogi rules.

The 1st version of the game came out, and I played against Aurelian Floria, and he suggested several improvements in my first version. I wanted to have different promotions of the knight, Gold General, and Lance. The Lance promotion bothered me, because after promotion it moved slowly. After discussions with Aurelian, we decided to make the Lance promotion to a Side Mover. I consider this game a collaboration of three people. Myself, Aurelian Floria, and Fergus Duniho.

Setup

Rules

This game follows the rules of Shogi. There are a few exceptions:

  • There is a Pocket that you can place any piece on the board into the pocket. This will take 1 turn to do this.
  • If there is a piece in the pocket, you can drop that piece onto the board. The standard Shogi rules for a drop apply.
  • The Gold General promotes to a Platinium General
  • The Promoted Knight has a new type of movement. It has the forward movement of a Gold General, the side movement of a Gold General, and the backward movement of a Standard Knight in Chess. Move down two squares (South), and the one square to the side. (See the Diagram below)
  • Currently, this game can only be played with the Symbolic Set of Shogi Pieces.

The Pocket: The pocket is an extra area that any of your pieces may move to, except for the King. To Move into the pocket, you must have a valid move on the board. A pocket move into the promotion zone and then back into the pocket will NOT promote the piece.

A promoted piece can move into the pocket and it is OK.  There is no demotion, when you move a piece from the board into the pocket. For example, if you move a Dragon Horse into the pocket it remains a Dragon Horse.

Note: the asymetrical start.  Black has a Copper General in the pocket, and White has the Copper General in Reserve.  This was designed to compensate the advantage that black has by going first.

 

k King King may move one space in any direction, but not into check. The object is to checkmate the King. The King may not move into the pocket.
g Gold General Gold General moves one space in any forward or orthogonal direction. It may not move diagonally backwards. A Gold General will promote to a Platinium General. z Platinium General Platinium General moves almost like a king.  It can not move directly backwards.  A captured Platinium General demotes into a Gold General.
r Rook Rook moves any number of spaces horizontally or vertically. It may not leap over pieces. When entering, exiting, or moving within the promotion zone, it may promote to a Dragon King. +r Dragon King Dragon King moves as the Rook or one space diagonally. A captured Dragon King demotes into a Rook.
b Bishop Bishop moves any number of spaces diagonally. It may not leap over pieces. When entering, exiting, or moving within the promotion zone, it may promote to a Dragon Horse. +b Dragon Horse Dragon Horse moves as the Bishop or one space orthogonally.

l Lance Lance moves any number of spaces vertically forward. It may not leap over pieces. When it moves into or within the promotion zone, it may promote. When it reaches the last rank, it must promote. +l Side Mover Side Mover moves from side to side like a horizontal rook, and the ability to move vertical 1 space. The Side Mover when captured, it demotes to a Lance.
n Knight Knight leaps to either of the two spaces it could reach by moving two spaces forward, followed by one more space left or right. When it enters the promotion zone, it may promote. When it reaches either of the last two ranks, it must promote. +n Promoted Knight Promoted Knight The piece has 1 forward movement of 1 space, 2 diagonal forward movements of 1 space (Left Forward or Right Forward), 2 side movements of 1 space (left or right), and a backward Knight movement of a Chess Knight. Backwards 2 spaces and then over 1 space. The backward movement is a Knight leap. When captured, it demotes to a Knight.

When it reaches the last rank, it must promote to a Silver General. +c Promoted Copper General Promoted Copper General moves one space forward. It can also move 1 space in any diagonal direction. This is the same movement as a Silver General. When captured, it demotes to a Copper General.
