Short description

Pawns that reach the a- or i-file are promoted as follows:

On the squares
a2, a8, i2, i8 they become a chancellor,
a3, a7, i3, i7 they become an archbishop and on
a4, a6, i4, i6 they become a queen.

If a pawn reaches the squares a1, a9, i1, i9, it becomes an amazon.

The king also promotes on the a- or i-file, maintaining its royal position and royal appearance as follows: from

a1, a9, i1, i9 the king is moving as an amazon, on
a2, a8, i2, i8 as a chancellor, on
a3, a7, i3, i7 as an archbishop and on
a4, a6, i4, i6 as a queen.

On the 5th rank, all pieces take on the function of a pawn, with the rook, knight, bishop, queen, archbishop, chancellor and amazon also mutating into pawns in appearance, while the king retains its function and royal presence.

The rook, knight, bishop and queen pieces are not upgraded during the game; they are downgraded on the 5th rank as described, but can be upgraded as pawns in the manner described above.

A king that has been given the move possibilities of a pawn on the 5th rank retains them for the rest of the game.

@H.G.

A quick note: When trying to add the variant to Game Courier, I noticed that the PTA (old/new) did not convert the pawns in the GAME code - see 'set morphers' and 'set morphs assoc'. This was easy to fix, but it seems that the automatic conversion can still be improved.

I have added the Game Courier solution to the description.
