Ruy Lopez: Morphy Defense, Modern Steinitz Defense (variation 2)

This opening is a solid defense that aims to control the center and develop pieces efficiently.

The opening begins with a symmetrical pawn structure, with both players vying for control of the center. Black's pawn move to d6 allows for the development of the light-squared bishop while maintaining a solid pawn structure. White's capture on c6 may seem to weaken Black's pawn structure, but it opens up the d-file for the rook and creates potential weaknesses in White's pawn structure as well. Black's pawn move to f6 aims to support the e5 pawn and prepare for potential pawn breaks in the center. Both sides have the opportunity to castle kingside and continue developing their pieces to prepare for the middlegame. This opening can lead to a balanced position with chances for both sides to play for the win.
