# Chess - Algebraic Notation Cheat Sheet by DaveChild

A guide to algebraic chess notation - how the squares are named, what the various symbols all mean, and how to mark up a game for sharing with other people.

### Algebraic Notation: Squares

 Board is always oriented with a white square at the bottom right. Squares are named from white's perspe­ctive Vertical columns are files, named a-h (always lower case) from left to right Horizontal rows are ranks, named 1-8 from near to far White king begins on square e1

### Algebraic Notation: Pieces

 Piece Code Symbol King K ♔ Queen Q ♕ Rook R ♖ Knight N * ♘ Bishop B ♗ Pawn [no letter] ♙
Pieces are always uppercase.
* In chess problems, "­S" is used to represent the Knight.

### Algebraic Notation: Moves

 The notation for a move indicates which piece is moved, and to where: Qa3 Queen moves to a3 Kh6 King moves to h6 b4 Pawn moves to b4 Where two identical pieces could move to the same square, the piece name is followed by its original file (or rank where the file is the same), like so: Rba3 Rook on b file moves to a3 N4f2 Knight on rank 4 moves to f2 cxd5 Pawn on c file takes d5

### Algebraic Notation: Symbols

 x Piece taken e.p. Piece taken en passant + Check # Checkmate = Pawn promotion * 0-0 Castle King-side 0-0-0 Castle Queen-side 1-0 White win ½-½ Draw 0-1 Black win (=) Draw offered
* e8=Q means e-file pawn promoted to Queen. The equals is often omitted.

### Algebraic Notation: Example

 1. e4 c5 White pawn to e4; Black pawn to c5 2. Nf3 d6 White knight to f3 3. Bb5+ Bd7 White bishop to b5, Black in check 4. Bxd7+ Qxd7 White bishop takes black bishop on d7, black in check; Queens takes d7 bishop 5. c4 Nc6 6. Nc3 Nf6 7. 0-0 g6 White castles king-side 8. d4 cxd4 White d4 pawn taken by c-file black pawn 9. Nxd4 Bg7 10. Nde2 Qe6 White knight on d-file to e2

### Algebraic Notation: Annota­tions

 !! Extremely strong move, often game-w­inning ! Great move !? Specul­ative move, possibly strong but more analysis needed ?! Dubious move, possibly weak but more analysis needed ? Bad move ?? Blunder, equivalent to hanging a piece +- White is winning +/- White has a signif­icant edge +/= White has a small edge = Equality ∞ Unclear advantage =/+ Black has a small edge -/+ Black has a signif­icant edge -+ Black is winning □ Only move available

### Variants

 Figurine Notation is used where notation needs to be indepe­ndent of language, and uses symbols instead of letters to represent pieces. Long Notation explicitly defines the start square for the moving piece, as well as the target square. Numeric Notation uses numbers instead of letters for pieces and for spaces.

S is "Springer" (jumper) and is a German notation only. It is not used in English

S is used in chess puzzles sometimes. No idea why the German letter was chosen ...

S is used in puzzles because N=Nightrider which is a fairy piece used in puzzles only.
