Bishop's Opening: "Modern" Berlin Defence
The "Modern" Berlin System is a strategic choice, initiated with the moves '''1. e4 e5 2. Bc4 Nf6 3. d3''', focuses on controlling the center and preparing for a solid game structure.

Key aspects of 3'''. d3''':


 * 1) Positioning of the Bishop: The move 2. Bc4 develops the bishop to a strong diagonal, targeting the f7-square, a key weakness in Black's position.
 * 2) Flexibility in Pawn Structure: The move 3. d3 supports the e4 pawn and prepares for a broader pawn structure. It also opens the diagonal for the light-square bishop and lays the groundwork for a potential kingside castle.
 * 3) Response to Black's Nf6: It challenges White's e4 pawn and develops a knight towards the center.
 * 4) Options for Further Development: White can further develop their pieces with moves like Nf3, O-O, and Re1, aiming for a solid central presence and potential kingside attacks. Also, 3. d3 defends the e4-pawn and opens up White's dark-square bishop.
 * 5) Strategic Considerations: This opening sets the stage for a game with strategic depth, where both sides aim to control the center and develop their pieces effectively for middle-game plans.
