Nimzowitsch Defense: El Columpio Defense, Pin Variation

One of the most common and aggressive opening moves in chess is e4, which strengthens control over the center squares on the board. By playing e4, White hopes to dominate the board and prevent Black from mounting a strong attack. However, the Nimzowitsch Defense is an effective way to counter this move. In particular, the Pin Variation involves Black sacrificing a pawn to gain a strong attacking position. After Nc6 and Nf6, Ng4 threatens to pin the knight on f3, forcing White to play e5 and enabling Black to play d6 and Nh6. By playing Bb5, White attempts to block Black's attack by pinning the knight on c6, but Black can respond with c6 to reinforce the knight and maintain pressure on White's center.

Nc6 is a solid opening move that aims to undermine White's control of the center by attacking the pawn on d4. Additionally, Nc6 prepares to develop the knight to a more active square, such as e7 or d7. By placing the knight on c6, Black also avoids potential pawn breaks such as d5 from White, which would force the knight to move again or risk being captured. In sum, Nc6 sets the stage for a flexible and dynamic defense against White's initial move.

Nf3 is a natural developing move that brings White's knight closer to the center of the board. By placing the knight on f3, White asserts more control over the d4 square and prepares to castle their kingside. Additionally, Nf3 opens up the possibility of playing d4 in the future, which would help to further solidify control over the center and put pressure on Black's pieces. In sum, Nf3 is a sound and standard response to Black's opening move of Nc6.

Moreover, by developing the knight, Black increases the mobility of their pieces and prepares to castle their kingside. In sum, Nf6 is a solid and useful move in this opening variation.
