The Soldier. It moves like a king, but is promoted like a pawn when it reaches the back rank, giving it the ability to move one or two squares in any direction, and can jump.
Imaginary chess: if you could invent a totally new piece to chess, what it could it be?
The Cannon. On your turn, instead of moving a piece, you can place the cannon on any square. You can't have more than two cannons. Cannons move one square horizontally or vertically. Alternatively, you can fire the cannon. It can fire as far as it needs to horizontally vertically or diagonally. Whichever piece the cannon hits is removed. The cannon can only hit one piece, but it can choose to fire over a piece in its way to hit a piece behind it. When firing, the cannon doesn't move. The cannon can't be captured, but it can be hit by your opponent's cannon.

So from my understanding, the Cannon is like a bishop from the diagonal moving am I correct or is it at least inspired by the bishop?
No, it moves like the wazir but can fire cannonballs across the board. can never move diagonally. The tiger was inspired by the bishop though.
Cat, mouse, and cheese. One player controls the cat, the other the mouse. Mouse moves one square in any direction. Cat moves one or two squares in any direction. If the mouse eats the cheese, the player controlling the mouse wins. If the cat eats the mouse, the player controlling the cat wins. The cheese stays stationary the entire game.
Pawn = mouse
Knight = cat
Rook = cheese
The squares the mouse can go to are blue
The squares the cat can go to are red
The Jester, moves two squares in any direction, or like a knight, the result is that the legal moves form a 5x5 square centered around the Jester. The Jester can jump over pieces.
Pawn = mouse
Knight = cat
Rook = cheese
The squares the mouse can go to are blue
The squares the cat can go to are red
this is actually a good concept, though i think the board should be a little bigger (like 10x10) and put the mouse closer to the cheese than the cat
otherwise i approve ![]()
thats like the most op thing ever like what

I was working on a chess engine that would let you create fairy pieces (the "official" term for new chess pieces) and script their behaviours.
I tried to make the script engine as open-ended as possible, so you could make very weird pieces.
For example a fun one was the lightning bishops, which moved like regular bishops, and you'd have a light and a dark-squared one. They couldn't capture by moving into pieces though. Instead, any time they were on the same rank or file you could use your move to activate the lightning, and any enemy pieces in-between the bishops would be removed from the board.
