Philidor Defense: Boden Variation

The opening move 1.e4 is a common choice for White, as it controls the center of the board and frees up pieces for movement. By playing 2.Nf3, White aims to prevent Black from playing 2...Nc6 and attacking e4 with a pawn. Black responds with 2...d6, which also controls the center and prepares for the development of the black knight. White then further strengthens their central control with the move 3.d4, which threatens to capture the pawn on e5. After Black captures on d4, White follows up with the move 4.Qxd4, which gains tempo by attacking the black bishop on c8. Black responds by moving their bishop to d7, which both protects the attacked knight and prepares for the eventual castling. This opening is part of the Philidor Defense and is commonly referred to as the Boden Variation.

The move 1.e4 by White controls the center and frees up the bishop and queen for movement. Black responds with 1...e5, mirroring White's move to also control the center and prepare to develop their own pieces. This opening is known as the Open Game and leads to a more open position with lots of options for both sides. By playing e5, Black not only strengthens their control of the center, but also prepares their knight to develop to f6 and the bishop to c5 or b4, putting pressure on White's position. In sum, e5 is a strong response that aims to gain control of the board and create opportunities for piece development.

In the Philidor Defense: Boden Variation, after the moves 1.e4 e5 2.Nf3, Black responds with 2...d6. This move supports the pawn on e5 and prepares to develop the knight to f6. By playing d6, Black also limits the options for White's light-square bishop, which can no longer move to g5 or attack the pawn on f6. While Black's pawn structure on d6 and e5 may seem slightly cramped, it also provides a solid base for their pieces and creates potential for pawn breaks in the future. In sum, d6 is a solid move that aims to control the center and prepare for further development.
