French Defense: MacCutcheon Variation, Bogoljubov Variation

The French Defense is a very popular opening in the game of chess, played after the moves 1.e4 e6. With 2.d4 d5, Black creates a strong pawn center, which White wants to attack. This is why White plays 3.Nc3, intending to exchange the knight on d5 and nullify Black's pawn advantage. However, 3...Nf6 attacks the e4-pawn, making 4.Bg5 necessary to defend it. After 4...Bb4, White has to decide how to deal with the pin on the knight. One common response is to play 5.exd5, exchanging the bishops and releasing the tension in the center.

Black plays e6 after the move e4 for several reasons. Firstly, it controls the d5-square, preventing white from playing d4-d5 and creating a strong pawn center. Secondly, it allows the bishop on c8 to be developed to d6 or b4, putting pressure on the central pawns. Thirdly, it prepares for a potential opening of the f8-bishop along the a2-g8 diagonal. In sum, e6 is a flexible and solid move that lays the foundation for Black's counterplay.

White plays d4 after 1.e4 e6 to gain control of the center and prepare for the development of the knights. By playing d4, White attacks the pawn on e6, forcing Black to either capture on d4 or support the pawn with d5. If Black captures, White recaptures with the queen, gaining an early lead in development. If Black plays d5 instead, the position often transposes into a Queen's Gambit Declined. In any case, d4 is a strong and logical move that contests Black's control of the center early on.

In the French Defense: MacCutcheon Variation, Bogoljubov Variation, Black wants to play d5 after 2.d4 to solidify their pawn structure and create a strong central pawn duo. By advancing the pawn to d5, Black also gains more space and puts pressure on White's e4-pawn. This move can also discourage White from playing 3.e5, as it would become a target for Black's pieces. However, playing d5 also creates a weakness on the d-file and limits the scope of Black's light-squared bishop. In sum, d5 is a dynamic move that aims to create active counterplay for Black.
