A Basic Guide to Openings (1.d4)

1.d4

Queen pawn openings are generally closed or semi-closed games (i.e., games characterized by fewer open lines) that have more positional play where the players try to slowly “strangle” each other. Currently, Black has increasingly moved away from symmetrical openings (1.d4 d5), tending to use the Indian defenses (1.d4 Nf6).

Why White Played 1.d4: 1. The pawn on d4 controls central square e5 2. The move frees the on c1 gives the Queen more scope.

White’s Basic Goals: 1. Control the Center. 2. Play e4 when possible 3. Quick and effective development of the pieces. 4. Castle (usually side) 5. Attack enemy King (usually king side)

B1-1A Orthodox Defense (50%) Considered a solid Defense for Black. Black gives White more central control but forces White to lose time (Bd3 followed by Bxc4). Black generally plans to exchange some pieces to free his cramped game and to play e5, freeing his game. White will use his space advantage and kingside pawn majority to attack

C. Queen’s Gambit Accepted (13%) With 2.dxc4, Black gives White the center but plays for free development of his pieces, especially the c8 Bishop.

Slave and Semi-Slav Defense

Slave Defense Semi-Slave Defense 1.d4 d5 2.c4 c6 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 c6

The Slave Defense is one of the main defenses to the Queen’s gambit. Unlike, the other defenses to the Queen’s gambit, it addresses the main drawbacks: the trapped c8 Bishop, an unbalanced , and a potentially pinned on f6.
