How to understand Chess Notation | Read Algebraic Moves, Replay Games and Decode PGN

CHAPTER 1 OF 12

1. Start with the board’s addresses

Back to contents

A chessboard becomes much friendlier when you stop treating its squares as anonymous patches of colour. Imagine a small town in which every house has an address. A move can then tell you where something happened without needing a photograph. The address stays fixed even if the camera turns around.

Place a board with White’s pieces nearest you. The files run from a to h across that view, and the ranks run from 1 to 8 away from White. A square combines a file and a rank: e4, b7 or h1. Lowercase letters name files; uppercase letters will soon have a different job. Find a1 before finding anything else, then trace its row and column with your finger.

Now turn the board around. The square e4 is still e4. It has not become d5 because you are sitting on the other side. This small point prevents a surprisingly large number of beginner mistakes. The notation refers to the board’s permanent coordinate system, not your current left and right.

Try an address walk. Touch a1, a8, h8 and h1. Then touch d4 and e5. Say each name aloud while looking at the printed coordinates. You are training a connection between the label and the location, so there is no prize for avoiding the labels too early. Use them until looking up a square becomes comfortable.

A useful checkpoint is being able to find six named squares without moving a piece. If the addresses still feel slow, practise the board before practising a long game. Otherwise you will ask your attention to solve two problems at once: where the destination is and which piece belongs there.

Here is an original exercise. Put a coin on c3 and another on f6. Which is nearer White’s starting side? Which file contains each coin? The first coin is on rank 3 and the second on rank 6, so c3 is nearer White’s starting ranks. No chess tactics are involved. You are simply reading the map that makes later tactics readable.

CHAPTER 2 OF 12

2. Read the moving piece before the destination

Back to contents

In English algebraic notation, K means king, Q queen, R rook, B bishop and N knight. Ordinary pawn moves omit a piece letter. The notation Nf3 therefore directs you to a knight move ending on f3, while e4 directs you to a pawn move ending on e4. These conventions are explained in the Chess.com notation guide.

The order in which you read matters. Start by identifying the kind of piece, then locate the destination, then look at the current position to find the legal mover. Saying “knight, f3” is easier than trying to swallow Nf3 as a mysterious word. Once those parts become familiar, the move begins to feel like an ordinary short instruction.

Set up the initial position. Read Nf3 and point to f3 before touching a knight. White’s knight on g1 can reach that square. The knight on b1 cannot. Move the correct knight, then look at the empty starting square. This last glance is a good habit: it helps you notice if you accidentally copied a piece instead of moving it.

Reset the board and read Nc3. This time the knight on b1 travels to c3. The move changes one piece’s location; it does not change the square names. You have just read two different instructions using the same piece letter, and the board supplied the information about where each knight started.

Now compare e4 and Ne4. The destination is the same, but the instructions describe different kinds of mover. Whether either instruction is legal depends on the position. A printed move is not a permission slip that lets a piece break its movement rules. If your board does not allow the recorded move, check how you reached that board.

Avoid memorising every possible combination of letters and squares. There are too many, and the combinations are built from reusable parts anyway. Learn the alphabet of pieces and the map of squares. Then practise joining them. That approach makes an unfamiliar move readable without requiring you to have seen it before.

Your checkpoint: explain Nf3, Bb5 and e4 in plain English. Then add one important qualification: without a position, you cannot always identify the starting square or confirm legality. That qualification is a sign of understanding, because chess notation describes movement inside a changing game.

CHAPTER 3 OF 12

3. Keep White’s and Black’s moves in order

Back to contents

Consider this short practice line:

1. d4 d5 2. Nf3 Nf6 3. c4 e6

The number introduces a full move pair. White’s move comes first, then Black’s reply. Read the line slowly: White plays d4, Black plays d5; White plays Nf3, Black plays Nf6; White plays c4, Black plays e6. Move one piece at a time on a board.

A full move pair contains two turns, often called two plies. If you confuse the pair with a single turn, your count will drift. The easy repair is to use two columns headed White and Black when practising. Write the move number at the left, then place each instruction in its correct column.

An excerpt such as 3...e6 identifies Black’s move at move number 3. The dots help you enter a discussion that begins with Black’s turn. They do not describe a special way the pawn moves. In annotations, numbering is part of the reader’s orientation.

Here is a small replay habit that pays off. After each pair, say who moves next. After 1. d4 d5, White moves next. After 2. Nf3, Black moves next. A beginner who keeps the correct side to move can catch many errors before they turn into an impossible position.

Notice another distinction: the written line can be compact, but the replay should still be sequential. Do not place White’s pawn on d4, White’s knight on f3 and White’s pawn on c4 while postponing all Black moves. That shortcut changes the order in which the position developed and makes captures or checks difficult to reconstruct later.

Try covering the second half of the line with a piece of paper. Reveal one token, make the move, then reveal the next. This turns a crowded paragraph into a manageable sequence. If you are reading a book, a bookmark can serve the same purpose without writing on the page.

Your checkpoint is a board with White pawns on d4 and c4, White’s g1 knight on f3, Black pawns on d5 and e6, and Black’s g8 knight on f6. Everything else remains on its starting square. Compare those landmarks with your board before adding another move.

CHAPTER 4 OF 12

4. Make captures visible on the board

Back to contents

A capture uses x. In Bxc6, a bishop captures on c6. A pawn capture includes its starting file: dxc6 means the pawn from the d-file captures on c6. The destination is where the capturing piece finishes, and the captured piece must leave the board.

Replay this familiar legal sequence from the initial position:

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6

Work through it in pairs. White’s king pawn advances, Black’s king pawn replies, the knights develop, White’s bishop reaches b5, and Black’s a-pawn moves to a6. White then uses the bishop on b5 to capture the knight on c6. Remove that black knight. Black’s pawn from d7 captures the bishop on c6. Remove the white bishop.

The final square c6 has been used twice in succession. That does not mean two pieces belong on it. After White’s capture it held White’s bishop; after Black’s reply it holds Black’s pawn. The board is a sequence of states, and each move replaces the previous state with a new one.

A reliable capture routine has three parts: identify the mover, remove the captured piece, and place the mover on its destination. Some people move first and remove second; that can also work. What matters is finishing with exactly one piece on the destination and an empty origin square.

Do not assume that x tells you the identity of the captured piece. The current position tells you what was on c6. The symbol records that a capture occurred. This is why a list of moves needs a starting position and correct replay: the letters alone do not contain every detail about the board.

Try narrating the final pair without piece abbreviations. “White’s bishop takes the knight on c6. Black’s d-pawn takes that bishop.” This is longer than the notation but useful while learning. Once you can explain the action clearly, the compact version becomes easier to remember.

Your checkpoint: after the sequence, the black knight originally on b8 and the white bishop originally on f1 are gone. Black has a pawn on c6 that started on d7. If you have the right pawn but still have the bishop, you decoded the words and missed the physical update. Repair that before continuing.

CHAPTER 5 OF 12

5. Separate special moves from ordinary destinations

Back to contents

Castling appears as O-O for kingside and O-O-O for queenside in standard game-file notation; printed scoresheets may use zero-shaped characters. Promotion commonly appears with an equals sign, as e8=Q. A plus sign marks check and # marks checkmate. FIDE’s Laws of Chess, Appendix C provide the official algebraic framework.

These symbols answer different questions. Castling tells you which special move occurred. Promotion tells you what a pawn became. Check and checkmate describe an effect on the opponent’s king. Read the core action first and its effect second. That makes a token such as axb8=Q+ much less intimidating.

For that token, say: the a-file pawn captures on b8, promotes to a queen, and gives check. This is a decoding example, not a claim that the move is legal in every position. You still need the board. The point is to take the instruction apart in a sensible order.

For castling practice, replay:

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. O-O

White’s king moves from e1 to g1 and the rook from h1 to f1. Both pieces move as part of White’s single turn. Check the two destinations rather than moving only the king and forgetting its partner.

Now reset and replay:

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. d3 Bc5 5. Nc3 d6 6. Be3 O-O 7. Qd2 a6 8. O-O-O

White’s king finishes on c1 and the a1 rook on d1. The queen has left d1, the bishop has left c1 and the knight has left b1. This longer example gives you a reason to track the earlier moves carefully: they prepare the space for the later special move.

A check sign should make you inspect the kings, not automatically remove one. Chess games do not end by capturing a king. With #, the position is checkmate, so the game ends. Result markers then tell you which side won or whether the game was drawn.

Your checkpoint is simple: recognise the category before trying to explain the whole token. Is it an ordinary move, a capture, castling or promotion? Does it also carry check or checkmate? You do not need to learn every rare combination on your first day.

CHAPTER 6 OF 12

6. Understand why some moves contain extra letters

Back to contents

Sometimes two pieces of the same kind can legally reach the same destination. A recorder then adds information to identify the mover. Nbd2 identifies the knight from the b-file going to d2. R1e2 identifies the rook from rank 1 going to e2. If neither file nor rank alone resolves the ambiguity, both can be supplied.

The useful question is “What information is needed to identify this mover?” This prevents extra letters from looking decorative. They are there because the simpler instruction would leave a choice. A clear record supplies enough information to remove that choice.

Replay this short preparation:

1. d4 d5 2. Nf3 Nf6 3. e3 e6 4. Nbd2

Before White’s fourth move, the knights on b1 and f3 can both reach d2. The extra b directs you to the one on b1. Move that knight and leave the knight on f3 alone. Check both squares afterward.

This example is especially useful because the destination is empty and nothing dramatic happens. The entire lesson is identification. If you always practise notation through spectacular checkmates, you may miss the quiet symbols that make an ordinary game replayable.

Do not use the visible possibilities alone when writing notation. Legality matters. A piece that appears able to move by its normal movement pattern may be prevented by the king’s safety. The relevant ambiguity concerns legal movers. For actual writing practice, a trusted analysis board can help confirm what information is required.

Think of two friends with the same first name. Sometimes a surname is enough; sometimes you need another detail. You do not add their complete biographies every time. Notation follows the same economical principle: include what distinguishes the piece in that position.

A common reading error is treating Nbd2 as “knight to b, then d2.” There is no intermediate stop. The b identifies the origin file, while d2 is the destination square. Read the token as a single completed move.

Your checkpoint: explain the difference between Nd2 and Nbd2 without relying on memorised opening names. Nd2 names a knight destination when the mover is clear. Nbd2 adds the origin file to make the mover clear. Understanding that purpose lets you decode a new example in a different game.

CHAPTER 7 OF 12

7. Replay a complete miniature without losing the position

Back to contents

Short games are excellent notation laboratories because you can reach the end before your attention becomes tired. The following miniature is a well-known checkmate pattern, used here for reading practice:

1. e4 e5 2. Bc4 Nc6 3. Qh5 Nf6 4. Qxf7# 1-0

Begin from the initial position. After the first pair, both king pawns occupy e4 and e5. After White’s second move, the bishop is on c4. Black’s knight goes to c6. White’s queen reaches h5. Black’s other knight reaches f6. White’s queen then captures the pawn on f7 and delivers checkmate.

Before accepting the final sign, inspect the position. The queen on f7 attacks the king on e8 and is protected by the bishop on c4. The position explains why the recorded ending is more than an ordinary capture. If you are new to king-safety rules, use a legal-move analysis board to inspect the final position.

Treat this as a reading example, not a recommended opening plan. A short trap can teach notation without becoming your entire chess strategy. The skill you are practising is faithful reconstruction: every piece should arrive at the correct square for the correct reason.

Record three landmarks on paper. After move 2, note the bishop’s square. After move 3, note the queen’s square. After move 4, note the captured pawn. Landmarks give you places to check the replay if a later instruction appears impossible.

Now ask a friend to read the line aloud while you move the pieces. Then exchange roles. The reader should pronounce the destination clearly; the mover should pause when uncertain. This small partnership is more effective than both people rushing toward the final position.

For an independent check, reset and replay the same miniature without reading the explanatory paragraph. If the board matches, you have transferred the decoding method into action. If it does not, find the first mismatch rather than starting a debate about the last move.

Finally, write the result in words. White won. The result marker tells you the outcome; it does not by itself tell you why the game ended. In this particular miniature, the final # supplies the checkmate information. In other records, a victory may follow resignation or another termination.

CHAPTER 8 OF 12

8. Know what PGN and FEN are for

Back to contents

Portable Game Notation, or PGN, stores game information and a sequence of moves in text. Forsyth–Edwards Notation, or FEN, describes a position. If your aim is to replay a game, PGN is usually the useful starting point. If your aim is to load a particular puzzle position, FEN is often the useful starting point.

The Chess.com PGN explanation introduces game headers and movetext. Its FEN guide explains the separate position format. These are different jobs, even though both help software share chess information.

Imagine a journey. PGN is the itinerary that tells you how the journey unfolded. FEN is a description of the place where you currently stand, together with game-state information that matters for what can happen next. A snapshot cannot automatically tell you the complete route taken to reach it.

Here is an original teaching PGN. The names identify practice sides, not real players or a historical event:

[Event "Notation practice"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "Practice White"]
[Black "Practice Black"]
[Result "*"]
1. d4 d5 2. Nf3 Nf6 3. c4 e6 *

The headers make the context readable. The moves are the sequence you already practised. The final asterisk records that a result is not supplied for this teaching fragment. It is not a command to move a piece.

When importing a record, first ask whether it is a full game or a fragment. A fragment that starts from a custom position needs that position supplied correctly. Starting every excerpt from the normal initial board is a common reason that legal game text seems impossible.

Keep an untouched copy of an imported record while practising. If you accidentally delete a move, alter a result marker or change a header, the original gives you a clean comparison. This is ordinary document care, and it becomes useful as soon as you start exchanging games.

You do not need to write FEN by hand to begin reading chess notation. Learn what the format is for, then let a board editor produce it when needed. The early goal is to choose the correct kind of information for the task, rather than memorising every field in every format.

CHAPTER 9 OF 12

9. Read comments without confusing them with played moves

Back to contents

A game annotation contains more than the moves actually played. It can include commentary, judgements and alternative lines. The reader needs to keep those layers separate. Otherwise a suggestion in the notes can accidentally become an extra move on the main board.

Symbols such as ! and ? usually express an annotator’s assessment. A brilliant-looking punctuation mark does not change the destination of the piece. Read the move first, then consider the judgement. Different annotators can disagree about a move, so punctuation is a prompt to investigate rather than a substitute for understanding.

Parentheses commonly introduce a variation in PGN movetext. Consider this original teaching fragment:

1. d4 d5 2. Nf3 (2. c4 e6) Nf6 *

The main line has White playing Nf3 on move 2 and Black replying Nf6. The parentheses offer an alternative in which White instead plays c4 and Black replies e6. Do not play Nf3 and then c4 as consecutive White turns. The variation branches from the position before the replaced move.

A physical board makes variations easier to manage if you work deliberately. Replay the main line first. Return to the branching position. Explore the alternative. Then reset to the main line before continuing. Photographing the branching position for your own reference can help, although a move list remains the better record for a long sequence.

Curly braces can contain a comment in a PGN, such as {White develops a knight.}. The words explain the position. They are not new moves. If you are learning, a short factual comment about what happened is often more useful than an ambitious judgement about what should have happened.

Try writing one comment after each pair in your practice game. Describe a visible change: a pawn entered the centre, a knight left its starting square, or a capture removed a bishop. This teaches you to connect the notation to the actual board without pretending to give expert analysis.

Your checkpoint is being able to point to three different layers: played move, alternative move and commentary. Once you can separate them, annotated games become less crowded. You can follow the actual game first and return to the discussion when you are ready.

CHAPTER 10 OF 12

10. Find the first replay error instead of guessing the next move

Back to contents

An impossible move is useful information. It tells you that either the record, the starting position or your reconstruction needs attention. The right response is to investigate the earliest mismatch. Guessing where the piece “must have meant to go” can hide the problem and damage every later position.

Use a small repair routine. Check the side to move. Check the destination square. Check whether you confused a piece letter with a file letter. Check whether a captured piece was removed. Check whether castling moved both pieces. Then compare the board with your last reliable landmark.

Suppose a bishop cannot reach the recorded destination because one of its own pawns blocks the diagonal. Look backward for a pawn move you may have skipped. The bishop instruction might be perfectly correct. The blockage may be evidence that the board never received an earlier update.

Suppose two black moves appear in succession. Look at the move numbering and any excerpt dots. You may have started reading midway through a pair, or accidentally jumped over White’s move. An error in turn order often looks like an error in piece movement.

Suppose a pawn capture leaves two pieces on the target square. Remove the captured piece before proceeding. Leaving it in place changes occupancy and can create a later contradiction even when the first capture sounded correct in your head.

For learning sessions, keep the record and your interpretation separate. Underline the token you cannot explain, then write what you think it means on another sheet. That preserves the evidence while giving you space to reason. If the source really contains a typo, you can document the correction rather than silently rewriting it.

Replay with a partner occasionally. One person reads and checks turn order; the other moves and checks squares. Change roles after a few moves. This makes the process less tiring and reveals which part of the task causes difficulty.

Your checkpoint: when a replay breaks, you can name the type of uncertainty. Is it an address problem, a piece-identification problem, a turn-order problem or a missing starting position? A precise question is easier to answer than “I don’t understand any of this.” It also gives you a clear place to practise next.

CHAPTER 11 OF 12

11. Build a short practice routine with visible progress

Back to contents

A good notation routine is small enough to repeat and varied enough to reveal progress. Ten attentive minutes can be more useful than an hour of moving pieces while half-reading a score. The aim is accurate reconstruction and clear explanation, with speed arriving later.

For the first session, practise square addresses. Ask someone to name a square, locate it, and read it back. Include edge squares and central squares. Stop when you can find them reliably; continuing until tired can turn a clear task into an unpleasant one.

For the second session, replay the quiet opening from Chapter 3. Use two columns and say who moves next. At the end, compare the six changed pieces with the checkpoint. You are practising continuity, the ability to keep the correct board through a sequence.

For the third session, replay the capture sequence from Chapter 4. Place captured pieces in a separate area. At the end, identify what left the board and where the recapturing pawn started. You are practising the difference between moving a piece and updating a position.

For the fourth session, replay kingside castling and then the longer queenside example. Check the king and rook destinations. Do not try to make the exercise harder by racing. A deliberate replay is successful if you can explain why the final squares are occupied correctly.

For the fifth session, import the teaching PGN into a compatible board or compare it with a manually replayed board. Step through one move at a time. Notice that software can manage the pieces while you still practise decoding the text.

For the sixth session, explore the variation from Chapter 9. Return to the branch point and explain which move the alternative replaces. If you can return to the main line without adding or losing a turn, you have learned an important reading skill.

For the seventh session, use a short game you played yourself. Write a few factual comments about the changing board. You may not yet know which moves were strongest, and that is fine. Accurate description comes before confident judgement.

Measure progress with three questions. Can I replay a short record without guessing? Can I explain the unfamiliar token by breaking it into parts? Can I identify and repair my first error? These are better beginner milestones than how quickly you can recite an opening’s name.

CHAPTER 12 OF 12

12. Answer the questions that usually interrupt a replay

Back to contents

Do I need to know algebra to read algebraic chess notation?

No equation solving is required. The name refers to a notation system. You need board coordinates, piece abbreviations and a few conventions. Start with a board beside you rather than trying to hold everything mentally.

Why is the knight N?

In English notation, K already identifies the king. Keep a small piece key beside your first few replays. Repeated use will make the distinction familiar without a special memorisation session.

Does e4 tell me where the pawn started?

It names the destination of an ordinary pawn move. The current position supplies the rest. From the initial board, White’s e-pawn reaches e4 from e2, but you should not turn that starting-square assumption into a rule for every position.

Can the same move token mean different actions in different games?

Yes. The position changes what pieces exist, where they stand and which moves are legal. Read the token together with the board, in the same way you interpret a short instruction together with its situation.

Does 1-0 mean checkmate?

It means White won. The final move and game context may explain the termination. A winning result alone does not prove that checkmate occurred on the board.

Should I learn old descriptive notation first?

For most modern beginners, start with algebraic notation. Older books may use different systems. Identify the notation before replaying rather than assuming the same abbreviations always mean the same thing.

Can I read notation without a physical board?

You can use a digital analysis board. Some experienced players read short lines mentally, but visualising an entire game is a separate skill. Using a board is a sensible way to learn and verify the moves.

Why does my imported game fail halfway through?

Check for a missing move, a damaged token, an incorrect starting position or a variation you accidentally merged into the main line. Compare with the original text. A failed import is a reason to investigate the record.

Does notation make me a stronger player immediately?

It makes games and explanations accessible. Improvement also requires understanding positions, practising decisions and reviewing mistakes. Notation is the doorway that lets you use those resources more accurately.

What should I read after this?

If replay is comfortable, continue with How to Learn Chess Quickly for the wider improvement process. For the broader idea of shared symbolic records, read How Notation Systems Work. Those routes serve different questions: how to train and why records preserve structure.
