Squares and Pieces
Notice the example squares marked on the board: b7, e1, g4
The rows going upwards are called “files” and can be specified by their letter, e.g. the c-file is the third row going upwards.
The rows going sideways are called “ranks”.
Apart from the pawn, pieces are given a letter.
R = Rook
N = Knight
B = Bishop
Q = Queen
K = King.
In the diagram both knights can move to d7 and both rooks can move to a4.
If possible use a file to specifiy which piece is moving. So for the knight on b8 moving to d7 we write Nbd7.
If both pieces are on the same file we use the rank to specifiy which piece. So for the rook on a1 moving to a4 we write R1a4.
Finally, all moves are given a move number. White’s first move is move 1 and black’s first move is also move 1 and so on. So if the first moves of the game are e4 e5 Nf3 Nc6 this is written as 1.e4 e5 2.Nf3 Nc6. If you are just specifying a black move without the white move before it you include …, e.g. black’s second move would be written as 2… Nc6.
If you are using a scoresheet you won’t have to write down the move numbers as they will be pre-printed.
