You can use this notation to play with your friends using only text messages or to record your games. It is very simple once you get used to it. Here's how it works:
- Every square has its name, which is one letter and one number.
- The number represents the distance from the white side (row).
- The squares on the white side have the number zero, the next 3 rows are 1, 2 , 3 and the black side is 4.
- The letter represents the column.
