Queen's Gambit Declined: Chigorin Defense, Modern Gambit

The moves 1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.Nc3 Nc6 lead to a dynamic pawn structure where Black maintains the pawn on c4 while developing pieces actively. Key ideas for Black include counterplay in the center and on the queenside, often looking to support the pawn on c4 with moves like ...e6 and ...Bb4. This setup appeals to players who enjoy unbalanced positions with tactical potential and prefer to challenge White’s plans directly rather than simply defending.
