Queen's Gambit Declined: Orthodox Defense, Rubinstein Attack (variation 2)

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

The Rubinstein Attack is a popular variation in the Queen's Gambit Declined, where Black aims to establish a strong pawn structure and solid position. By fianchettoing the bishop and playing c6, Black prepares to challenge White's central pawns while maintaining flexibility in their pawn structure. The move a6 prevents White from advancing their b-pawn and potentially creating a passed pawn on the queenside. The queen maneuver to c2 allows White to support the central pawns and prepare for potential pawn breaks in the center. Both sides typically continue to develop their pieces and prepare for the middlegame, with Black often looking to counterattack in the center or on the queenside. Overall, this variation offers a balanced and strategic battle for both players, with opportunities for tactical play and long-term planning.
