Center control is an important aspect of playing chess, most openings are built around controlling the center, but why? Is center control really that important for winning a game?
The center is the crossroads of the board. Controlling it will give you access to every other part of the board. At the same time, it will drive a wedge in the opponent's position that hampers communication between king and queen side.
Control of the center is usually a decisive advantage in your favor; unless your opponent has heavy compensation (e.g. more than a pawn of material advantage), or a violent attack against your king.
The piece in the center four square can move to more positions than in it is in any other positions on the board. So if you can get control of the center positions, you have more options and this gives us an advantage over the opponent.
Controlling the center allows you to move your pieces to the other side of the board easier.
Further, some pieces (especially knights) have more moves if they're in the center of the board. A knight in the center has 8 moves. A knight on the rim has 4, 3, or 2.
