How to Read Chess Notation (Algebraic Notation Basics)

Once you know a handful of symbols, a cryptic-looking line like "1. e4 e5 2. Nf3 Nc6" turns into a readable sequence of moves.

  1. Learn the board's coordinate grid

    Files (columns) are labeled a through h from White's left to right, and ranks (rows) are numbered 1 through 8 starting from White's side. Every square has one unique label, like e4 or g7.

  2. Identify the piece letters

    K is king, Q is queen, R is rook, B is bishop, and N is knight (not "K," since that is already taken by the king). Pawns are the exception: a pawn move is written with no letter at all, just the destination square, like e4.

  3. Read a simple move as piece plus destination

    A move like Nf3 means "knight moves to f3." A pawn move like e4 means "a pawn moves to e4." The notation tells you what moved and where, without needing to say where it started, since usually only one piece can make that particular move.

  4. Spot a capture with "x"

    An "x" before the destination square means a capture happened there, such as Nxf3 for "knight captures on f3" or exd5 for "pawn on the e-file captures on d5."

  5. Recognize check and checkmate symbols

    A "+" at the end of a move means it puts the opposing king in check. A "#" means it is checkmate, ending the game.

  6. Spot castling notation

    O-O means castling kingside (the shorter side), and O-O-O means castling queenside (the longer side), regardless of which player is castling.

  7. Spot pawn promotion

    When a pawn reaches the far end of the board, notation adds an equals sign and the new piece, such as e8=Q, meaning the pawn promoted to a queen on e8.

Why algebraic notation replaced older systems

Chess was once commonly recorded in descriptive notation, which described moves relative to each player's own side of the board and required different labels depending on which color was moving. Algebraic notation uses one fixed grid for the whole board, which is shorter, unambiguous, and is now the standard used in essentially all modern chess publishing and software.

Reading a full game score

A full game is written as a numbered sequence of move pairs, White's move followed by Black's response, like "1. e4 e5 2. Nf3 Nc6." Once the individual symbols are familiar, following an entire recorded game or replaying a famous match becomes a matter of working through the list one pair at a time.

Frequently Asked Questions

Why is the knight written as "N" instead of "K"?

"K" is already used for the king, so knight uses "N" instead to avoid confusion between the two pieces.

What does it mean when two pieces could make the same move?

Notation adds a disambiguating letter or number from the starting square, such as Nbd7 (specifying the knight starting from the b-file), when two knights could otherwise both move to d7.

Do I need special software to read algebraic notation?

No — once you know the symbols, you can read it directly from a book, a website, or a scoresheet, though many people also use a physical or digital board to follow along visually while reading a game.
