Queen's Gambit Accepted1. d4 d5 2. c4 dxc4
In the Queen's Gambit Accepted Black takes the pawn on c4 but he can hardly defend it and as a rule he returns it. White temporarily has the chance to achieve superiority in the centre. But in return Black gets a chance to carry out a counter-attack on White's centre in the opening, especially with the move ...c7-c5.
Queen's Gambit Accepted - .main variation: 1. d4 d5 2. c4 dxc4 3. Nf3 Nf6 4. e3 e6 5. Bxc4 c5 6. 0-0 a6
In the main variation both sides develop a knight and White quickly recovers his pawn. On the other hand, Black continues according to plan with the move …c7-c5 and attacks the white centre. After move 6, with which Black is planning the advance …b7-b5 and then the fianchetto of his light-squared bishop, White has several equally good continuations. He can prophylactically retreat his bishop to b3, prevent the advance …b7-b5 with 7. a2-a4 or take on c5 and offer an exchange of queens.
Queen's Gambit Accepted - central variation: 1. d4 d5 2. c4 dxc4 3. e4
This is an ambitious plan. White immediately occupies the centre with a second pawn and would like to take the c4-pawn with his light-squared bishop. Black attacks the white centre either with 3...Ng8-f6 or with 3...e7-e5. The central variation leads quickly to contact with the opposing side and requires a precise plan early in the game.
