Introduction

Board Arrangement

There are three main boards of 4x4 squares - White's Defending board, the Neutral board, and Black's Defending board. In addition, there are four movable Attack boards, initially positioned as shown.

The board arrangement is shown in Figure 1. It is assumed that there are two levels from one main board to another, counting the attack board level as one whether there is an attack board there or not. This will become more clear in the Board Notation section. Of course, a piece may only stop on a level if a board is actually present.

Notice the colors of squares are the same vertically. This has implications for piece movement.

Each main board has a pin at each of its four corners. The attack boards can attach to these pins, either above or below the main board.

Board Notation

The board notation is formatted as follows :

(piece)-[from](file)(rank)(level)-[to](file)(rank)(level)

The coordinate system is shown in Figure 3. As an example, the White Queen's starting position is b1A. Moving the Queen to Black's defending board is represented as Q-b1A-b6F.

Castling is denoted as O-O.

The Attack Board's move is written as follows :

A-[from](attachment file)(attachment rank)(Attack Board level)-[to](attachment file)(attachment rank)(Attack Board level)

The destination is the square where the Attack Board attaches. The level is the level of the Attack Board playing surface. As an example, the Black King's Attack Board can be moved in several ways as follows :

A-e9G-b9G

A-e9G-e6G

A-e9G-e9E

Starting Positions

Starting positions for all the pieces are shown in Figure 2.
