The game requires a 9 x 9 board. The pieces change depending on the color of the square reached or the rank achieved.

Setup

Pieces

Standard set of pieces - plus archbishop, chancellor, amazon and dragon horse. Details in the rule section.

Rules

Except for the following changes, the Fide rules apply.

There is no capturing en passant, castling and promotion of pawns takes place.
Bare king loses.
Stalemate is a win.

With the exception of the pawns, pieces are played as in standard chess - regarding archbishop, chancellor, amazon and dragon horse see below.

In Morphomania pieces change their appearance and function depending on the color of the squares they reach or the rank they achieve.
The king is excluded from this.

The rook mutates from black to white to a chancellor and back again from white to black to a rook.

The knight mutates from white to black to an archbishop and vice versa.

The queen becomes an amazon when changing from white to black; the amazon becomes a queen again when changing from black to white.

A bishop on ranks 1, 3, 5, 7, 9 remains a bishop. At ranks 2, 4, 6, 8, the bishop mutates into a dragon horse.
A dragon horse at ranks 2, 4, 6, 8 mutates into a bishop when it gets to ranks 1, 3, 5, 7, 9.

The dragon horse and bishop can change color diagonals using the dragon horse's wasir move option!

A pawn remains a pawn on white squares. As soon as it reaches a black square, it mutates into a speedpawn.
In reverse, the speedpawn mutates into a pawn when it moves from a black to a white square.

The pawn moves one square forward and captures opposing pieces. If an opponent's piece is two squares away, it can be captured if there is no other piece in between. The pawn does not jump over pieces.

The speedpawn moves one or two squares forward and captures opposing pieces. If an opponent's piece is three squares away, it can be captured if there is no other piece in between. The pawn does not jump over pieces.

Castling: This is a move of the king and either rook of the same colour along the player’s first rank, counting as a single move of the king and executed as follows: the king is transferred from its original square three squares towards the rook on its original square, then that rook is transferred to the square just next to the king.

Morphomania. Morphing wherever you look. (9x9, Cells: 81)

I can understand the changes/restructuring you have made. I am confident that a human player will be able to cope with the current description of the game. Incidentally, I think we have already spent enough time making changes, so I kindly ask you to publish the current status. Thank you for your efforts.

I've restructured the page to flow more consistently: the pawns are still the last of the non‐royal pieces discussed but are now grouped with the other colour‐dependent morhpers, which means the Bishop is now described first; the unorthodox moves are now all described in a single block at the end of the page; both (down from all three) morphing tables are in the condensed form describing square‐dependent states rather than transitions.

I've left most of the other text intact (except a typo ‘Kight’ and the description of the DH's move, which is more in line with the others but feel free to adjust it if you prefer to express it differently).

Please tell me if you're happy to go with the edits I've made; if so (and subject to any other adjustments you may wish to make — e.g. to the description of the DH or if you want to have the tables as images similar in style to the ones you made previously) I'm happy to publish

You're quite right - I'm guessing at what you mean. I am therefore grateful for your offer to change the page as you mean it. Sorry you have the work now, wasn't my intention.

I didn't expect a screenshot of my comment ;‌) Assuming you still prefer to chenge them, ideally either something similar in style to your existing images or outright HTML tables would be better

Also (perhaps more importantly) I'd assumed it to be implicit that the other tables would match in style ;‌) And arguably the pawn could be included in the picec table as the conditions on its morphing are the same; only the bishop strictly needs a separate table (though if you consider the pawns to be fundamentally different from other pieces I guess you wouldn't be alone). Only reason I didn't do it is because the alfaerie Diagram Designer set seems to lack the Speedpawn image.

As to the structure: the Dragon Horse diagram is next to the other unorthodox non‐pawns now, but the pawns are now awkwardly between two different kinds of non‐pawn piece and the order of exposition differs between the ‘general’ and ‘detailed’ sections

If you prefer, I can edit the page myself to show what I mean, and you can tell me if you disagree with the proposed presentation; thus might be more efficient than trying to explain verbally and would save you unnecessary busywork guessing at what I mean
