pawn | Pawn is a quick and small scripting language

I am making a chessboard and my main problem is that after I set up the first two rows of the board, the pawn insertion alters the color of the dark squares.

So the board has the class "main" and is colored white, the squares(class="box) are either the same color as the board (white) or brown. The component (pawn) is an SVG. Upon adding the pawn ID to a square, it nullifies the squares color. This is fine for the white squares, but a problem with the brown squares.

here is the code

I am trying to design a chess board GUI with PyQt. The board is comprised of frames. When I place a transparent PNG of a chess piece, the PNG is colored with the background of the window, thus covering the frame underneath. When there is no background color set to the window, the piece, and the square beneath it display properly. How could I set the image to not cover the frame square underneath it with the window background color?

Here is a screenshot of the output:

I want to create a web app chess game, so every piece will have an event listener to wait until a player clicks on it. When a player clicks on a piece (for now I'm only working with pawns) it's id will be saved and printed out, and only after this all squares should wait for a click (I'm not working with valid squares, can be any square); and if a square is clicked, it's id should be saved and printed out.

But on console, when I click a pawn, it's id is printed twice, one time for the normal print, but another time for the square print (So it took square's print). So instead of the programm to wait to call the function that prints the square id after clicking the piece, the programm prints the piece id in the place of the square id. So I think the programm is not waiting until the first function is finished:

Hey I'm making simple console game in C++. We have pawns on board (I made it using 2D dynamic array). I want to check if there is space to move our pawn. My simplest and best idea would be if I could check every square next to the pawn. The problem, however, arises when the pawn is in the corner of the board. (x-1,y), (x, y+1) , (x+1, y) , (x, y-1) [this means every field around our pawn]. My board is 2D dynamic array. So if I check field e.g. array[-1][0] (this means field x: -1, y: 0) of course it goes out of memory range. And my question is, Is it good if I go outside this range anyway but I will make a condition in case of this error?

I build Gource project. Compile error comes when doing make.

Build enviroment use libboost_filesystem.so.1.53.0.

I wanted to create a dictionary of values called pieces,
the key of the given dictionary had to be the name of the piece and the item it's Unicode charachter representation.

I decided to write a list comprehension to retrieve the Unicode charachters and a list with all the names that I needed.

I've finished my chess game, but now I'm implementing a numpy array as the board so the chess AI I'm working on calculates faster. I know what a KeyError is, but I don't understand why its happening here. Error:

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:
