Queen's Gambit Declined: Orthodox Defense, Rubinstein Attack (variation 3)

This opening is a solid defense for Black against the Queen's Gambit Declined, focusing on developing pieces and controlling the center.

In this variation, Black aims to fianchetto their bishop on the kingside while maintaining a solid pawn structure in the center. White typically builds up a strong pawn chain with pawns on d4 and e3, preparing for a central pawn break later on. Black's plan usually involves playing c6 and d5 to challenge White's central control, followed by developing the pieces harmoniously. The move Rc1 is a flexible move, preparing to support the c4 pawn or potentially doubling rooks on the c-file. Qc2 is a useful move for White, connecting the rooks and preparing for a potential kingside attack. Both sides will continue to develop their pieces and maneuver for control of the center, with strategic pawn breaks and piece exchanges likely to occur in the middlegame. Overall, this variation offers both sides opportunities for active play and strategic maneuvering.
