Black declines the c4 pawn with ...e6, leading to classical positions with a pawn structure battle. One of the most solid Black defenses.

A solid setup with Bf4, e3, and Nf3. Popular for its reliability and quick development without deep theory. Works against almost any Black response.

A dynamic version of the London where White plays Qc1 and b4 to create early pressure before standard setup. More aggressive than the classical London.

A sophisticated system where White combines d4, c4, and g3 (often with Bg2). Related to the QGD, it creates a strong pawn center with a fianchettoed bishop. Solid and space-advantaged.

Black captures the pawn, giving White a spatial advantage and better development. Classic strategic play with clear plans for both sides.

Lines to refute the Englund Gambit where Black sacrifices a pawn for quick counterplay. White must play accurately to maintain the advantage.
