How to Read Chess Notation — Algebraic Notation Explained
Every famous game in chess history is written down using the same simple system. Once you understand algebraic notation, you can follow any game ever played — from Fischer vs Spassky to last night's tournament. It takes about ten minutes to learn.
Why Notation Matters
Chess notation lets you record, share, replay, and study games. Without it, a brilliant combination would disappear the moment the pieces were put away. With it, you can replay Kasparov's 1999 "Game of the Century" against Topalov move by move, or analyse your own game the next morning.
Every serious chess site, book, and puzzle uses algebraic notation. Understanding it unlocks a huge library of chess knowledge that would otherwise be inaccessible.
The Board: Files and Ranks
The chessboard is a grid of 64 squares. Each square has a unique address made of a letter and a number.
- Files run vertically (up-down) and are labelled a through h from left to right (from White's perspective).
- Ranks run horizontally (left-right) and are numbered 1 through 8, with rank 1 being White's back row.
So the square in the bottom-left corner is a1 (White's queen-side rook starting square). The square in the top-right corner is h8 (Black's king-side rook starting square). The centre squares are d4, d5, e4, and e5.
Piece Letters
Each piece has a capital letter abbreviation in English notation:
- K — King
- Q — Queen
- R — Rook
- B — Bishop
- N — Knight (K is taken by King, so Knight gets N)
- Pawns have no letter — a square name alone means a pawn moved there.
Reading a Basic Move
A move is written as the piece letter followed by the destination square. For example:
- Nf3 — Knight moves to f3
- Bd6 — Bishop moves to d6
- Qe4 — Queen moves to e4
- e5 — Pawn moves to e5 (no letter for pawns)
Moves are listed in pairs: White's move first, then Black's. A game starts like this: 1. e4 e5 2. Nf3 Nc6 3. Bb5 — that's the Ruy López opening in three moves. White plays e4, Black plays e5, White plays Nf3, Black plays Nc6, White plays Bb5.
Captures
A capture is written with an "x" between the piece and the destination square.
- Bxe5 — Bishop captures the piece on e5
- Nxd4 — Knight captures on d4
For pawn captures, include the file the pawn came from: exd5 means a pawn on the e-file captures on d5. This is important because two pawns might both be able to capture to the same square, so you need to know which file it came from.
Disambiguation: Two Pieces Can Go to the Same Square
If two identical pieces can both move to the same square, you need to specify which one. You do this by adding the file or rank of the piece that moved.
- Rad1 — Rook on the a-file moves to d1 (the other rook is on a different file)
- N1f3 — The knight on rank 1 moves to f3 (distinguishes from a knight on a different rank)
- Rfe1 — Rook on the f-file moves to e1
Special Moves
Check (+): A plus sign at the end of the move means the king is in check. Rd8+ means Rook to d8, giving check.
Checkmate (#): A hash symbol means checkmate. Qh7# means Queen to h7, checkmate.
Castling: Kingside castling is written O-O (two capital letter O's, not zeros). Queenside castling is O-O-O.
En passant: Written like a regular pawn capture, sometimes followed by e.p. to clarify. exd6 e.p. means the pawn on the e-file captures en passant to d6.
Promotion: When a pawn reaches the back rank, the promoted piece is written after the square: e8=Q means the pawn promotes to a Queen on e8. You can also write e8(Q).
Annotation Symbols
Beyond the basic notation, you'll often see these symbols in annotated games:
- ! — Good move
- !! — Brilliant move
- ? — Mistake
- ?? — Blunder
- !? — Interesting or speculative move
- ?! — Dubious move
These symbols make annotated game books much more readable — when you see Qxf7?? you know someone just made a terrible blunder.
Putting It Together
Here is the start of a famous game (Fool's Mate, the fastest possible checkmate):
1. f3 e5 2. g4 Qh4#
Read it: White plays f3 (pawn to f3), Black plays e5 (pawn to e5), White plays g4 (pawn to g4), Black plays Queen to h4 — checkmate. Two moves for White, two for Black, game over. Now you can read it.
