chess notations

While playing chess you may have noticed some characters (from a to h) and some numbers (1 to 8) on the edges of border squares. These numberings make a huge part of chess that is recording a chess game!
Chess game can be saved in any data base in form of PGN which is a direct procedure of how the game went on. The numberings make the chess board of 64 squares a Spreadsheet in which refer to each square like a1 becomes the the first row intersected with first column making the square formed "a1", similarly goes for all 64 chess squares. 

Chess notation Procedure

How does chess notation work?

Now in a chess game there are some more rules for recording the chess game, starting the game with white (always), First white makes the piece move then presses the clock and then writes the notation on sheet.

Chess notations are followed up in a procedure that if one moves a piece lets say queen to the square a1 then the notation would be written like - "Qa1"

How to write notation in chess?

So writing notation in chess is super easy you just have to follow some steps :

Set up the board correctly: Ensure the board is oriented so that White’s pieces start on ranks 1–2 at the bottom and Black’s on ranks 7–8 at the top.

Number your moves: Begin each turn with the move number followed by a period (e.g., “1.”, “2.”, etc.).

Use piece symbols: K for King, Q for Queen, R for Rook, B for Bishop, N for Knight; pawns have no letter.

Record source and destination squares: Write the file and rank of the square a piece moves from and to (e.g., e2–e4).

Indicate captures: Insert “x” between source and destination (e.g., Nxe5). For pawn captures, include the file (e.g., exd6).

Mark check and checkmate: Add “+” for check and “#” for checkmate after the move.

Handle special moves: Use “O-O” for kingside castling and “O-O-O” for queenside castling; for pawn promotion, append “=Q” (or R, B, N as applicable).
