rooks | Essential React custom hooks ⚓ to super charge | Frontend Utils library

I am trying to program a chess computer. I am having a weird problem with a dictionary here. As you can see in the code below, I am only editing the pieces attribute of the Player object saved at 'w' in my dictionary self.players. However, when I run the code, for both Player objects created (Player('w') and Player('b')), the d[(1,1)].piece object appears in their respective Player.pieces['R']. How can this be? (In the code, only the class Board should be really important however I included the other classes so the code works).

I'm training the following model:

I'm currently just starting off coding in c++, the current project I'm working on is making an in-console chess engine type thing. The function below is supposed to check if a particular square has a piece on it, and if so, if the piece is white. Board.grid is a 2D array of strings where " " would be an empty square, "wR1" one of the white rooks, "bQ1" the black queen, etcetera. I got the error expected primary-expression before '.' token on both if statements inside the functions and think it's got to do with the .at() function called on the 'square string', but have no clue why this would give an error or what could be done to resolve it.

I would appreciate it greatly if anyone could help me with this. Thanks in advance!

I want to predict a the current chess board using pytorch/keras. (Let's not worry about the input for now.)

How would I got about that? A chess board has 8x8 positions (64) on each position could be a black or white piece (12) or no piece at all (1). I am planning on using this representation for the chess board (other suggestions are welcome!): https://en.wikipedia.org/wiki/Board_representation_(computer_chess)#Square_list
For example:

I am attemping to create a chess game. I have created 64 divs for the chessboard with the function chessSquares. When I created these I pushed the elements into an array called array which consists of the 64 divs that I created and appended to the chessboard.

The next two functions is the yCoord and xCoord. With these two functions I created div elements with the coordinates for the chessboard and appended to the chessSquares. These elements are the outer elements on the left and top side of the chessboard which display coordinates.

With the following function otherCoord I am trying to make an evaluation where if the id numbers of the elements in array do not match the ID numbers in the array of arrayXYCoord then to push the elements into the array of arrayInnerCoord.

After I do this I will be using a function to assign ID's to the other squares of the chessboard followed by coordinates which can be toggled on and off.

I have tried various ways of doing this such as running two loops at a time and it ends up pushing the id's multiple times into an array and it just seemed really messy. I am looking for a clean way to do this with a simple comparison.

If possible, I would like to use a method from javascript.info/array-methods. Thank you

I am trying to write a program that will return True if the white king on a chess board is in check. The pieces on the board are generated as a string and formatted as such, where the lowercase values are white and the uppercase are black.:

I'm trying to solve a problem where based on a chessboard (grid variable below) and a provided location of a rook, remove any elements from my grid variable (the chessboard) that contain the same x value or same y value as the rook (as rooks only move vertically and horizontally across the board).

I want to create a 64 components array showing all the squares in which the two rooks of an empty chessboard could move from their current position. So far I am doing it with for and while loops.

Let's say I want to see if the first item in one string is the same first item as the second string in the array. I also want to check if the last item of the first string aligns with the last item of the second string in the array. See below of the example.
