Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An alphanumeric grid (also known as atlas grid) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number. An advantage over numeric coordinates, which use two numbers instead of a number and a letter to refer to a grid cell, is that there can be no confusion over which coordinate refers to which direction. Algebraic chess notation uses an alphanumeric grid to refer to the squares of a chessboard.
