Chess notation is a standardized system for recording and describing moves in a chess game. It is an essential skill for anyone who wants to study chess, watch and follow live games, or participate in chess tournaments. Here is a brief guide on how to read chess notation:

1. Each square on the chessboard is assigned a unique name based on its rank and file. The files are labeled a through h, from left to right, while the ranks are labeled 1 through 8, from bottom to top.
2. Each piece is represented by an abbreviation: K for king, Q for queen, R for rook, B for bishop, and N for knight.
3. When a piece moves, its abbreviation is followed by the name of the square to which it moves. For example, if a knight on g1 moves to f3, the notation would be Nf3.
4. If two pieces of the same type can move to the same square, the file or rank of the starting square is included. For example, if two knights are on the board, and one moves to f3, the notation would be Nf3d2 or Nf3e5, depending on which knight moved.
5. Captures are indicated by an "x" between the moving piece and the square where the capture takes place. For example, if a pawn on e5 captures a pawn on d4, the notation would be exd4.
6. Castling is indicated by the notation "0-0" for kingside castling and "0-0-0" for queenside castling.
7. Check is indicated by the symbol "+", and checkmate is indicated by "#".
