Petrov's Defense (variation 4)

A solid and counterattacking opening where Black aims to equalize the position by putting pressure on White's central pawn.

---

This opening is characterized by Black immediately challenging White's central pawn with a knight move. By doing so, Black aims to create imbalances in the position and put pressure on White's pawn structure. White has the option to either defend the pawn or capture Black's pawn on e5. If White chooses to capture, Black can recapture with the knight, maintaining a strong presence in the center. This leads to a symmetrical pawn structure with both sides having equal chances. Black can then continue to develop pieces and prepare for a solid midgame strategy. Overall, Petrov's Defense (variation 4) is a reliable opening choice for players looking to play solidly as Black and equalize the position early on.
