What is Chess Notation?
Chess notation is the system for reading and writing moves in algebraic notation — the standard used on scoresheets, in books, and on every online platform. Each square has a name built from a file letter (a–h) and a rank number (1–8), so the board becomes a grid of coordinates like e4 or f7. A move names the piece and the square it lands on: a pawn move is just the destination square (e4), a piece move adds a capital letter for the piece (Nf3), and captures, checks, castling and promotion each have their own symbol. Learn to read notation once and every game ever recorded opens up to you.
A Brief History
Modern algebraic notation grew out of the older descriptive system, in which the same move could read as 'P-K4' or 'Kt-KB3' and depended on whose side you were sitting on. Algebraic notation fixes every square to a single absolute name regardless of which player is moving, which made it far less error-prone. FIDE adopted algebraic as the official standard in 1981, and it is now the notation you will meet in essentially every book, database, and app.
The Building Blocks
Files are letters a–h
The eight columns of the board are lettered a to h, from White's left to White's right. The a-file is on White's queenside edge, the h-file on the kingside edge. A file letter is always lowercase and always comes first in a square name.
Ranks are numbers 1–8
The eight rows are numbered 1 to 8, counting up from White's side. Rank 1 is White's back rank, rank 8 is Black's. Combine the file and rank and you get the square: e4 is the e-file, fourth rank — the square in front of White's king's pawn.
Pieces are capital letters — the pawn has none
Each piece uses one capital letter: K king, Q queen, R rook, B bishop, N knight (N, because K is taken). A pawn has no letter at all — a pawn move is written as just the destination square. So Nf3 means a knight to f3, while e4 means a pawn to e4.
How to Read a Move — Step by Step
The Coordinate Grid
Every square has an address: a file letter (a–h) across, then a rank number (1–8) up. The square in front of White's king is e1's neighbour e2, and two steps on is e4. Name a square file-first, rank-second — always.
Reading a Pawn Move: e4
White pushes the king's pawn from e2 to e4. A pawn has no letter, so the move is written as just the destination square: e4. You never write the starting square for a pawn — only one pawn can reach any given square.
Reading a Piece Move: Nf3
The knight on g1 develops to f3. A piece move puts the piece's capital letter first, then the destination: Nf3. The knight uses N because the king already owns K.
Reading Castling: O-O
With f1 and g1 clear, White castles kingside: the king goes e1→g1 and the rook h1→f1. Castling has its own symbol — O-O for the kingside (short) side, O-O-O for the queenside (long) side.
Common Misconceptions
The pawn has a letter like the other pieces
The pawn is the only piece with no letter. A move written as just a square — e4, d5, h6 — is always a pawn move. If you see a capital letter, it is one of the other five pieces.
A capture is written with the square of the piece you took
A capture always names the square the capturing piece moves to, not the piece removed. Nxe5 means your knight lands on e5; the thing that was on e5 is simply gone from the board.
N stands for nothing in particular, or means something else
N is the knight. The natural letter K already belongs to the king, so the knight borrows N (from kNight). Beginners who read N as 'no piece' or as the king get every knight move wrong.
Can You Read It?
Write the move for each position
Write the pawn move
It is the very start of the game, White to move. White wants to advance the king's pawn two squares. What is the notation for that move?
Write the capture
White to move. The white pawn on e4 can capture the black pawn on d5. How do you write this capture in algebraic notation?
Write the castling move
White to move, with the f1 and g1 squares clear and the king not in check. White castles kingside. What is the notation?
Notation in Your Openings
These openings are where you first read notation in action
Ruy Lopez
The Ruy Lopez begins 1.e4 e5 2.Nf3 Nc6 3.Bb5 — three lines of notation that pack in a pawn move, two knight moves, and a bishop move. Reading these fluently is the first step to studying the most analysed opening in chess, where the move order and the exact square each piece lands on carry real theoretical weight.
View opening pageItalian Game
1.e4 e5 2.Nf3 Nc6 3.Bc4 is the Italian Game, and it is where most players first meet castling notation: after the pieces come out, O-O tucks the king away. Learning to read Bc4, O-O, and the capture symbols here lets you follow annotated Italian lines move by move.
View opening pageSicilian Defense
The Sicilian starts 1.e4 c5 — a pawn move answered by a pawn move on the opposite wing — and quickly branches into sharp lines full of captures like Nxd4 and cxd4. Because Sicilian theory is written almost entirely in notation, comfortable reading is what turns a wall of symbols into a game you can replay.

Pitfalls to avoid when reading notation
Reading the pawn capture from the wrong side
A pawn capture like exd5 names the file the pawn started on (e), not the file it ends on. Beginners who read the leading letter as the destination place the pawn on the wrong square and lose the thread of the game. Remember: for pawn captures the leading letter is the source file, and the square after the x is where the pawn actually goes.
Confusing O-O and O-O-O
O-O is kingside castling (the king travels a short distance to g1/g8); O-O-O is queenside (a longer journey to c1/c8). Mixing them up when replaying a game puts your king on the wrong wing and every following move stops making sense. Count the O's: two for the short side, three for the long side.
Ignoring the check and mate symbols
The + and # symbols are not decoration — + tells you the move gives check and # tells you the game just ended in checkmate. Skimming past them means you miss that a king is in danger, or you keep reading a game that is already over. Treat every + as a demand to deal with a check.
Tips for Club Players
Say each square out loud as file-then-rank — 'e, four' — until the coordinate grid is automatic; the file letter always comes before the rank number.
A move written as a bare square (e4, d5, h6) is always a pawn move — the pawn is the only piece with no letter.
For a pawn capture, the first letter is the pawn's starting file: exd5 is the e-pawn taking on d5, not a piece called E.
Remember N is the knight, because the king already claimed K — read every N as a knight and every K as the king.
Two O's (O-O) is kingside castling; three O's (O-O-O) is queenside — count them before you move your king.
Treat + as 'check — deal with it now' and # as 'checkmate — the game is over'; never skim past those two symbols.
Frequently Asked Questions
Everything you need to know about chess notation
Chess notation is the standard way to write down chess moves so any game can be recorded and replayed. The modern system, algebraic notation, gives every square a name from a file letter (a–h) and a rank number (1–8). A move names the piece and where it goes: a pawn move is just the square (e4), a piece move adds the piece's capital letter (Nf3), and captures, checks, castling, and promotion each have their own symbol.
They are the piece letters: K is the king, Q the queen, R the rook, B the bishop, and N the knight. The knight uses N because K was already taken by the king. The pawn has no letter at all — when a move is written as just a square with no capital letter in front, it is a pawn move.
A capture uses the symbol x before the destination square. For a piece it looks like Nxe5 (knight takes on e5). For a pawn you write the pawn's own file first: exd5 means the e-pawn captures on d5. In every case the square after the x is where your piece ends up, not the piece that was removed.
O-O is kingside castling, the shorter castling move where the king goes to g1 (or g8 for Black) and the rook jumps beside it. O-O-O, with three O's, is queenside castling toward the a-file, where the king lands on c1 (or c8). The extra O reflects the longer distance the queenside rook travels.
