Standard Chess is a programming language, that is designed to look like a chess game. It was created by MasterWoodie in 2023

Moves

Standard Chess uses Chess Notation:

Piece	Notation
King	K
Queen	Q
Rook	R
Bishop	B
Knight	N
Pawn	Nothing

The position is defined by a letter (a-h) and a number (0-8)

Special Moves:

Move	Notation
Capture	x in front of the position
Check	+ behind the position
Castle	0-0 or 0-0-0
Pawn Promotion	=<Piece> behind the move
Mate	#
Draw	1/2

Structure

In a Standard Chess Program only chess moves are allowed.
The language operates on a tape, where each cell can hold a value between 0 and 255
Important: Every Standard Chess Program needs a result (Mate or Draw)

The commands of the program are based on the piece:

Piece	Description
King	Flow control: a = check? or take?, j = currentValue is not 0?, dif = positionLetter - positionDigit, amount= 1 if a: amount = nextMove as number if j: no move if dif > 0: move instruction pointer left by amount if dif < 0: move instruction pointer right by amount(if a: exclude nextMove)
Queen	Random Stuff: a = check? or take?, dif = positionLetter - positionDigit if dif is 0: currentCell = randomNumber if dif is 1: currentCell = if a: cellPointer else length of output if dif is 2: currentCell = if currentCell is 0: 1 else 0 if dif is 3: currentCell = if a: nextMove as number else 0
Rook	Tape Movement: a = check? or take?, dif = positionLetter - positionDigit, amount = 1 if a: amount = nextMove as number if dif > 0: move cell pointer left by amount if div < 0: move cell pointer right by amount
Bishop	Input/Output: a = check? or take?, dif = positionLetter - positionDigit, amount = 1 if dif > 0: take input -> if a: a number else a character if div < 0: output current cell -> if a: as a number else as a character if div is 0: if a: amount = nextMove as number; remove amount characters from output and set currentCell = value of last character -> if amount is 0: clear output and set currentCell = value of first character
Knight	Arithemtic Operations: a = check? or take?, dif = positionLetter - positionDigit, amount = 1 if a: amount = nextMove as number if dif > 0: remove amount from current cell if div < 0: add amount to current cell
Pawn	no command, except on promotion, in which case it will evaluate like it is the promoted piece

To turn a move into a number, it first must be a normal move -> no castle, mate or draw
for the position -> evaluate as a base 8 number, where the letter is the 10th place, both places are first reduced by 1 (to have the digits 0-7)
if the move is a take add 127 to the number
if the move is a check add 64 to the number

Additionally there are a few more commands:

Command	Description
0-0	start of loop
0-0-0	jump to start of loop
Mate or Draw	end program
