Forsyth Notation
The Forsyth Notation allows us to record where the chess pieces are on the board in a quick and easy way.
Look at this position:

|
In Forsyth notation this position would be recorded as:
r1bq1rk1; pp3ppp; 3n4; 2p1N3; 2B5; 7P; PPP2PP1; R1BQR1K1. |
The pieces are represented by their letter symbols (For example, Q = Queen, R = Rook etc.). The letter symbols for Black are written in lower case and for White they are written in capitals. Empty squares are represented by a number. For example, 1 means there is one empty square, 2 means there are two empty squares and so on.
The position is recorded rank by rank starting with the eight rank (a8) and the ranks are seperated by semi-colons.
Thus r1bq1rk1; means on a8 there is a Black Rook, then an empty square (b8), a Black Bishop (c8), a Black Queen (d8), an empty square (e8), a Black Rook, (f8), a Black King (g8) and an empty square (h8). See diagram below.

3n4; means on row 6 there are three empty squares, then a Black Knight, and 4 empty squares as shown in the diagram below.

If a whole row contains empty squares like this:

it is recorded as 8;
The position on the right would be written:
4kb1r; p4ppp; 4q3; 8; 8; 1B6; PPP2PPP; 2KR4. |
