Take charge of central squares

The central squares e4, d4, e5 and d5 are power controlling squares in a game of chess and the pieces can cause maximum influence on the game from these squares. Generally the player who can occupy these squares can attack and defend and usually end up winning the game.

In the game which follows Black turns the tide in his favour after his queen is placed on the d5 square. From there on the queen controls the game and Black has no problem in winning the game.
