Chess Patterns ❯ Control of Lines ❯ Control of Open File

Control of Open File

You Control an Open File when you place your Rooks or Queen on a file that has no pawns. In the diagram above, White controls the open d-file, this restricts Black's movements, and creates opportunities for penetration in the position.

Ideas for when you control an Open File: (1) Consider doubling your Rooks, (2) Use the open file to penetrate your opponent's position, (3) Advance your Rooks to the seventh or eighth rank to increase their impact. Ideas for when you play against the control of an Open File: (1) Block the open file with a pawn or piece, (2) Contest the file by placing your own Rooks on it, (3) Strengthen your back rank to prevent potential tactics, (4) Create counterplay on other files or diagonals to divert your opponent's attention.

This recent work by Eugene Perelshteyn is unique. It contains roughly 200 exercises, similar to many workbooks. However, the focus here is not on calculation. The positions have to be "evaluated". Obviously, we think it’s a must-read.
