Pterodactyl Defense: Fianchetto, Queen Pteranodon

Chess is a game of strategy, where every move counts. In the opening phase of the game, White aims to control the center of the board and develop their pieces efficiently.

After Black's move g6, White plays c4 to gain additional control over the center of the board.
