Algebraic Chess Notation Calculator

Chess players, whether beginners or advanced, need a clear way to record and analyze moves. The Algebraic Chess Notation Calculator helps you convert moves into standard algebraic notation (SAN) and long algebraic notation (LAN) instantly.

This tool ensures accurate chess notation for games, analysis, training, or tournament records, making it easier to track moves and strategies.

Why Use an Algebraic Chess Notation Calculator?

  • Quick Conversion: Instantly see SAN and LAN for any move.
  • Accurate Recording: Capture pawn moves, piece captures, promotions, castling, checks, and checkmates correctly.
  • Game Analysis: Helps study positions and strategies efficiently.
  • Learning Tool: Beginners can understand move rules and notation conventions.

How to Use the Algebraic Chess Notation Calculator

  1. Piece Type: Select the piece (Pawn, Knight, Bishop, Rook, Queen, King).
  2. From Square: Enter the starting square (e.g., e2).
  3. To Square: Enter the destination square (e.g., e4).
  4. Move Type: Choose whether the move is normal, a capture, check, checkmate, or castling.
  5. Promotion (Pawn Only): If a pawn reaches the 8th rank, choose a promotion piece.
  6. Disambiguation (Optional): Specify file or rank to clarify moves (e.g., d for file or 3 for rank).
  7. Annotation (Optional): Mark moves as good, brilliant, mistake, or blunder.
  8. Click Calculate: Get instant SAN, LAN, distance moved, and full notation with annotations.
  9. Reset: Clear the form to try new moves.

Example Move

Suppose you move a pawn from e2 to e4:

  • Piece: Pawn
  • From Square: e2
  • To Square: e4
  • Move Type: Normal

Calculator Output:

  • SAN: e4
  • LAN: e2-e4
  • Piece: Pawn
  • Distance Moved: 2 squares
  • Full Notation: e4

If the move is a capture, check, checkmate, or promotion, the notation updates automatically with symbols like x, +, #, or =Q.

Special Moves Handled

  • Castling Kingside: O-O
  • Castling Queenside: O-O-O
  • Pawn Promotion: Automatically adds =Q, =R, =B, or =N
  • Captures: x is included in SAN and LAN
  • Check / Checkmate: + for check, # for checkmate

Benefits of Using This Calculator

  1. Efficiency: Save time writing moves manually.
  2. Accuracy: Prevent mistakes in SAN or LAN.
  3. Learning Aid: Understand chess notation conventions.
  4. Game Recording: Perfect for tournament or personal game analysis.
  5. Flexible: Works for all standard chess pieces and moves.
