Nimzo-Indian Defense: Romanishin Variation (variation 3)

This variation of the Nimzo-Indian Defense is a solid and flexible option for Black, allowing for dynamic piece play and control of the center.

In this variation, White typically aims to establish a strong pawn center with moves like d4 and c4, while Black immediately puts pressure on White's position by pinning the knight on c3 with Bb4. After Nf3, Black strikes at the center with c5, challenging White's pawn structure. By castling kingside, Black ensures the safety of their king while preparing to connect the rooks. White's move g3 signals a fianchetto of the bishop on g2, aiming to control the long diagonal and support the center. Black responds by castling kingside, completing their development and preparing to mobilize their pieces for the upcoming middlegame. This opening often leads to complex and strategic positions where both sides have chances for active play and counterplay.
