How to Read Chess Notation

1. Every square has a name

The board is a grid of files (columns) labelled a to h from White's left, and ranks (rows) numbered 1 to 8 from White's side. A square is named by its file then its rank: e4, d5, g1. This never changes — e4 is e4 whether you are playing White or Black.

One orientation check before anything else: the bottom-right corner square must be light. If it is dark, the board is turned the wrong way and every coordinate you read will be wrong.

• Files are letters a–h, ranks are numbers 1–8.
• Squares are written file first: e4, not 4e.
• White's home ranks are 1 and 2; Black's are 7 and 8.

2. Piece letters and basic moves

Each piece has a capital letter: K king, Q queen, R rook, B bishop, N knight (N because K is taken). Pawns have no letter at all — a move written as just a square, like e4, is a pawn move.

A move is the piece letter plus the destination square: Nf3 means a knight goes to f3. When two identical pieces could reach the same square, add the file or rank of the one that moves: Nbd2 (the knight from the b-file) or R1e2 (the rook on rank 1).

• K Q R B N — knight is N; pawns have no letter.
• Move = piece letter + destination square (Nf3, Bc4, Qd2).
• Disambiguate with the file or rank when two pieces can reach the square.

3. Captures, checks, castling and promotion

A capture uses x: Nxe5 means the knight captures on e5. Pawn captures include the pawn's starting file: exd5 means the e-file pawn captures on d5. En passant is written by destination square, optionally with e.p.

A check is +, checkmate is #. Castling kingside is 0-0 and queenside is 0-0-0 (some books use O-O with letters). Promotion is written with an equals sign: e8=Q means the pawn reaches e8 and becomes a queen. Draw offers, results and clock times are recorded separately: 1-0 White won, 0-1 Black won, ½-½ draw.

• x = capture, + = check, # = checkmate.
• 0-0 kingside, 0-0-0 queenside castling.
• e8=Q for promotion; 1-0, 0-1 and ½-½ for results.

4. Annotation symbols in books and workbooks

Annotators grade moves with a small set of symbols: ! a strong move, !! brilliant, ? a mistake, ?? a blunder, !? interesting and worth considering, ?! dubious. Positional assessments use ± (White clearly better), ∓ (Black clearly better), = (equal) and ∞ (unclear).

These symbols carry a lot of meaning in very little space, which is why annotated game collections are the densest study material available. When a workbook writes 21.Nxd5!! ±, it is telling you both that the move is spectacular and that the resulting position is winning for White.

• ! strong, !! brilliant, ? mistake, ?? blunder, !? interesting, ?! dubious.
• = equal, ± White better, ∓ Black better, ∞ unclear.
• Symbols are how annotated collections compress an entire verdict into two characters.

5. Reading a full game score and PGN

A game score is numbered by move pair: '1.e4 e5 2.Nf3 Nc6 3.Bb5' means White's first move, Black's reply, and so on. When a text quotes only Black's move it uses three dots: 3...a6.

PGN (Portable Game Notation) is the same thing in a computer file, preceded by tags in square brackets for event, players, date and result. Any PGN can be pasted into a board viewer to replay the game move by move — which is how you should study every annotated game you meet.

The fastest way to make notation automatic is to play through annotated games on a real board, one move at a time. That is exactly how the 200 annotated master games in The Master Study Library are laid out: one diagram per key move, so you never lose your place.

• Move numbers count pairs: White's move then Black's.
• '3...a6' means the move belongs to Black.
• PGN files replay in any viewer; annotated games are the fastest way to internalise notation.
