# Symmetron! 44

## Introduction

Symmetron! 44 is a competing entry in the current 44-square contest.

Its two main characteristics are:

• Several pieces can change to their "hippogonally symmetrized" version (that is, turning their orthogonal moves into diagonal moves and vice versa), but through different mechanisms.
There is a piece in Symmetron! which has the ability to change the movement of some adjacent friendly pieces to a symmetrized type: the SHS, or Self-Hippogonal-Symmetrizer. When adjacent to a friendly SHS, an Advancer-Rook changes automatically its movement to that of an Advancer-Bishop, and the Dragon-Bishop movement changes to Dragon-Rook. (We prefer these terms to Dragon-Horse and Dragon-King.) This is automatic symmetrisation by adjacence, in this case, adjacence to a SHS.
The Pawns and Bawns have a natural symmetrization by capture, They have another symmetrization available, they can change into each other when adjacent to a friendly SHS. This is permanent symmetrization by adjacence.
The King moves according to position. Inside its six-square Palace, it moves one step orthogonally, but outside its Palace, the King's move changes to the symmetrized type, one step diagonally. This is symmetrization by position.
Of course, the Knight is already symmetrized.
(For the record, the yet undecided larger version of Symmetron! should feature Can(n)ons. This will be optional symmetrization after moving, or as a move.)

• Each Player has a Launching Square, which is accessible only to the Reducer, the SHS, or the Knights when they change owner, Shogi-like.

## Board and Setup

The 44-square Board is composed of a 6x7 rectangle or Arena, plus two Launching Squares (one for each player, as in Pocket Mutation Chess).
