Openings Against D4 Chess Puzzles

“Openings against d4” is a broad label for Black’s replies to 1.d4, especially the King’s Indian Defense, Nimzo-Indian Defense, Queen’s Gambit Declined, Slav Defense, Grünfeld Defense, Dutch Defense, and Benko Gambit. Their defining feature is that Black challenges White’s central pawn duo with moves such as ...Nf6, ...d5, ...c5, ...f5, or ...e6 rather than allowing 1.d4 to become a completely free space advantage. The exact position depends on the move order: for example, 1.d4 Nf6 2.c4 g6 leads toward the King’s Indian, while 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 defines the Nimzo-Indian.
