Center control

The four main central squares are d4, e4, d5, and e5; those letters and numbers are board coordinates. Center control means influencing these squares with pawns or pieces. A square is controlled when one of your pawns or pieces attacks it according to its movement; this usually makes the square dangerous for the opponent to occupy.

The center connects both sides of the board. A player who controls it often gains shorter routes for the pieces, more attacking and defensive options, and better conditions for development, the process of activating pieces from their starting squares. Center control can also create space, meaning more useful territory for maneuvering while the opponent has less room.

Control is not the same as occupation. A pawn may stand in the center, but a bishop or queen can influence it from far away. Central occupation is usually most valuable when it can be supported; an advanced pawn without support may become a target. Centralization places pieces near the center, while control can be exerted from many different squares.
