Algebraic notation records each move by the piece letter and the destination square. It is how games, puzzles and lessons are written.
Key principles
- K, Q, R, B, N name the pieces; pawns have no letter
- x marks a capture, + a check, # checkmate
- O-O is castling kingside, O-O-O queenside
- Add the file or rank when two pieces can reach the same square
Common mistakes
- Forgetting the disambiguating file or rank
- Writing the starting square instead of the destination
