Unlike the case with files, rank names are always given from the point of view of each individual player. They then attack the two squares diagonal ly in front of them or one if the white pawn occupies the first or last file on the board and as these squares are empty - they are not attacking anything. The columns are called as files.

On other types of boards, orthogonal direction s are those that pass from space to space through shared sides. The white king must reach the key squares to win. The reason these are key squares is because you will be able to take the opposition , or force zugzwang , because of the spare tempo. ROOK A piece that looks and is sometimes called a castle. It can be confusing, because the "castle" in chess is a verb.

In algebraic notation, we use a system of alphanumeric co-ordinates to identify each square. On the other hand a square is a hole even if it can be control led in the future with a pawn that has made a capture. That would not be in keeping with justice. The second rank - ie.

A horizontal side-to-side line on the chessboard. Rapid Chess Chess played with a fast time control see "time control".

First, they are important for notating or reading games. In addition, in a game, heavy pieces rooks and queen seek special files that are described in this section. In chess notation, a file is used to designate every square, which has an alphanumeric name. In addition, the file is required to record each move. In the following position, White has just played Bb The "B" stands for the piece, which is a bishop, and "b5" refers to the square.

The b5-square is on the b-file and the fifth rank. In a game of chess, files are fought for by rooks and queens. Because they move up or down vertically as many squares as they can, open and semi-open files are very important for these pieces. In the following example, White controls the only open files with their rooks:. The white rooks are more active than the black rooks and threaten to infiltrate Black's position by moving to the seventh rank.

The rooks are even more active on the seventh rank! Note that controlling the seventh rank would not be possible without first controlling the open files. Now that you know what files are and why they are important, let's test your ability to take control of a file! In the following position, it is White to move.

Is there an open file? If so, how can White take control of it? Rb1 takes control of the open b-file. White can now double their rooks on the b-file and then infiltrate Black's territory! Let's try one more! In the following position, White has full control of the e-file. After a few captures on the e8-square, White delivers checkmate! Very good! You now know what a file is, why files are important and how to take control of them!

Use this new knowledge in your own games and may you control many open files! Why Are Files Important? The d-file is highlighted. The e-file is open. The c-file and e-file are both considered semi-open. There are no open or semi-open files in this position; they are all closed files.
