In practice the long algebraic notation is only used by players learning the game. Most of the time chess players use the short algebraic notation.
This is almost the same notation, but with the starting position and the hyphen left out.
But now some moves have to be disambiguated. If two (or more) identical pieces can move to the same square, the letter indicating the piece is followed by (in descending order of preference):
- the file of departure if they differ
- the rank of departure if the files are the same but the ranks differ
- both the file and rank if neither alone uniquely defines the piece
