Tjatoer!

I’m just going to flat-out say that I am in no way good at coding, I am even confident in saying I’m very bad at it! Still, I’ve found this video series tutorial on youtube by Eddie Sharick on how to make a chess game and chess engine in python, And I followed it through.  Now that we’ve got that out of the way, let us talk about Tjatoer! It is pronounced tʃɑtur (Chatoor) which means chess in Indonesian, though it is spelled in archaic forms of spelling for novelty’s sake, I guess. I scaled up the board up from 8x8 to a whopping 16x16, enabling both players to have more space, and of course allowing the way for more powerful pieces. You can have all the necessary files of this project on my GitHub repository that I will link on the end of this page.

Setup

Initial piece setup in Tjatoer!

This is the Initial piece setup in Tjatoer! You may notice that I put colored outline boxes on the board, this won't show in the actual program but I wanted to categorize the pieces in the game since there is so many, from white's perspective, namely:

Pieces

If you're wondering, yes! I designed all the pieces myself, here they are with their names:

From left to right, downwards, the Archbishop, Chariot, Duchess, Esquire, Fürst, Gajah, Hawk, Imam, Jester, Lugal, Mullah, Oknha, Shrook, Thalia, Upasaka, Viscount, Warrior, Xiphodon, Yishi, Zorro


Not to forget the regular chess pieces, (again, you can have these designs on the GitHub repo that I will state below). Regarding the pieces, below are their descriptions and move diagrams, I will reference the Piececlopedia as best as I can, though some the pieces' names are all jumbled from the ones there:

Xiphodon (Moves and captures one square orthogonally then moves and captures any distance diagonally, notated by the letter X, is on the Piececlopedia here)

Viscount (Moves and captures one square diagonally then moves and captures any distance orthogonally, notated by the letter V, is on the Piececlopedia here)

Oknha (Moves and captures like a gajah and queen, notated by the letter O, is not on the Piececlopedia)

Fürst (Moves and captures like a knight and queen, notated by the letter F, is on the Piececlopedia here)

Lugal (Moves and captures like a gajah, knight, and queen, notated by the letter L, is not on the Piececlopedia)

Esquire (Moves and captures like a hawk and rook, notated by the letter E, is not on the Piececlopedia)

Duchess (Moves and captures like a hawk and bishop, notated by the letter D, is not on the Piececlopedia)

Mullah (Moves and captures like a king and knight, notated by the letter M, is on the Piececlopedia here)

Zorro (Moves and captures like a knight but can do it continuously, notated by the letter Z, is on the Piececlopedia here)

Imam (Moves and captures like a rook and knight, notated by the letter I, is on the Piececlopedia here)

Archbishop (Moves and captures like a bishop and knight, notated by the letter A, is on the Piececlopedia here)

Hawk (Moves and captures like a gajah and a knight, notated by the letter H, is on the Piececlopedia here)

Chariot (Moves and captures like a gajah and rook, notated by the letter C, is on the Piececlopedia here)

Gajah (Moves and captures like a knight but longer, won’t be obstructed by enemy or ally piece, notated by the letter G, is on the Piececlopedia here)

Jester (Moves and captures like a gajah and bishop, notated by the letter J, is on the Piececlopedia here)

Yishi (Moves and captures like a knight and thalia, but only one square diagonally backward, notated by the letter Y, is not on the Piececlopedia)

Upasaka (Moves and captures like a knight and shrook, but only one square backward, notated by the letter U, is not on the Piececlopedia)

Pawn (Moves slightly different from regular chess, still notated by the letter P)

Shrook (Moves and captures a maximum of two squares orthogonally, notated by the letter S, is not on the Piececlopedia)

Thalia (Moves and captures a maximum of two squares diagonally, notated by the letter T, is not on the Piececlopedia)

Warrior (Moves like a king but can only capture 2 squares forward, Notated by the letter W, is not on the Piececlopedia)

If that's too much to wrap around the head, here's a hopefully helpful table for quick and easy reference

And that's it for the pieces.

Rules

Neatly, the total types of pieces in this game is 26, one for each letter of the alphabet, In addition to those new pieces, I also tweaked some rules to befit the game, such as:

And that's all the new rules! pretty simple considering other variants here.

Notes

I am well aware that this game is horribly imbalanced and lacking in playtesting, to add that, this game is obviously impractical for human vs human play, but I designed it as a stress test for fairy chess engines, and it seems to be working, the engine that I wrote struggles to go even on depth 2! I haven't figured out how to hook it up to other fairy chess engines though, so if anyone is up for that challenge, be my guest. You can follow the development of this project on my GitHub repository here
