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

This opening is a solid defense for Black against the Ruy Lopez, focusing on developing pieces and controlling the center.

In this variation, Black aims to establish a strong pawn structure by playing d6 early on, preparing to support the center with c5 or d5. By delaying the development of the knight to f6, Black avoids some of the main lines of the Ruy Lopez and keeps the option of playing Nf6 later. White typically continues with Nc3, reinforcing the center and preparing for further development. Black can then continue with Nf6, challenging White's central control, or continue with c5 to counterattack in the center. This opening often leads to complex and dynamic positions where both sides have chances for active play. It is a flexible choice for Black, allowing for a variety of pawn structures and piece placements depending on White's responses.
