The Queen's Gambit Accepted is a variant of the Queen's Gambit , an opening to the game of chess . The Queen's Gambit accepted is a Closed Game and is classified under the ECO codes D20 to D29. Each of its main variants begins with the following moves ( see also: chess notation ):
1. d2-d4 d7-d5
2. c2-c4 d5xc4
The queen's gambit is not a typical pawn sacrifice in the opening ( gambit ) because, in contrast to the king's gambit, for example, blacks cannot defend the pawn in most variants without being disadvantaged.
Wilhelm Steinitz successfully applied the opening by giving White an isolated queen's pawn. Siegbert Tarrasch added a question mark to 2.… d5xc4, because Black ' surrendering the center '. His influence was so great that the adopted Queen's Gambit was used less often.
In contrast to the Queen's Gambit rejected , Black is able to develop his bishop from c8 to g4. Counterattacks with… e7 – e5 or… c7 – c5 are possible without losing a tempo as in the Slavic Defense .

Main line after 3. Nf3 Nf6 4. e3 e6 5. Bxc4 c5 6. 0–0 a6
The main variations of the Queen's Gambit adopted include:
- 3. Ng1 – f3 (should prevent e7 – e5)
- 3.… Ng8 – f6 4. e2 – e3 e7 – e6 5. Bf1xc4 c7 – c5 6. 0–0 a7 – a6 is the most common continuation.
- Semjon Abramowitsch Furman plans the move Rf1 – d1 after 7. Qd1 – e2. More 7.… b7 – b5 8. Bc4 – d3 c5xd4 and e3xd4, as is so often the case in the Queen's Gambit, leads to White Isolani on the d4 square.
- With the Rubinstein - Botwinnik variant 7. a2 – a4 White prevents Black's advance ... b7 – b5 at the price of a weakening of the b4 square.
- The prophylactic withdrawal 7. Bc4 – d3 is called the Ingorn variant.
- The other prophylactic retreat 7. Bc4 – b3 also wants to answer 7.… b7 – b5 with 8. a2 – a4 in order to effect… b5 – b4 with a weakening of the field c4. Nb1 – d2 is necessary, but also very useful.
- 3.… Ng8 – f6 4. Nb1 – c3 a7 – a6 5. e2 – e4 b7 – b5, with this sequence of moves a real gambit emerges. 6. e4 – e5 Nf6 – d5 7. a2 – a4 Nd5xc3 8. b2xc3 Qd8 – d5 9. g2 – g3 Bc8 – b7 10. Bf1 – g2 Qd5 – d7 11. e5 – e6 and 8.… Bc8 – b7 shows the white thrust. The theoretical effort involved in this continuation is enormous, as Black can turn into the Slavic Defense with 4.… c7 – c6 or into the Vienna Variation with 4.… e7 – e6 5. e2 – e4 Bf8 – b4 .
- 3.… a7 – a6 4. e2 – e3 Bc8 – g4 ends in the Alekhine system. Alexander Alekhine first played this variant when he was black at the 1934 World Chess Championship against Efim Bogoljubow .
- 3.… Ng8 – f6 4. e2 – e3 e7 – e6 5. Bf1xc4 c7 – c5 6. 0–0 a7 – a6 is the most common continuation.
- 3. e2-e3 can 3. ... e7-e5 to and results of the fourth Lf1xc4 e5xd4 5. e3xd4 by diverter the French exchange variation (to mock there 1. e2-e4 e7-e6 2. d2-d4 d7-d5. 3 e4xd5 e6xd5 4. c2 – c4 d5xc4 5. Bf1xc4).
- 3. Nb1 – c3 also allows e7 – e5.
- 3. e2 – e4. With this central variant, the white players need much more specific variant knowledge than with the quieter playing styles. Black meets this ambitious and at the same time obligatory system by immediately attacking White's center with 3.… e7 – e5 (4. Ng1 – f3 e5xd4 5. Bf1xc4 Nb8 – c6 6. 0–0 Bc8 – e6), or by means of 3 .… Ng8 – f6 4. e4 – e5 Nf6 – d5 5. Bf1xc4 Nd5 – b6 or prepared with 3.… Nb8 – c6.

A failed attempt to protect the black pawn on c4 (1. d2 – d4 d7 – d5 2. c2 – c4 d5xc4 3. e2 – e3 b7 – b5? 4. a2 – a4 c7 – c6 5. a4xb5 c6xb5 6. Qd1 -F3).
The attempt to maintain the Gambit pawn on c4 (by means of the cover 3.… b7 – b5) fails because of the weakening of the black queenside :
1. d2 – d4 d7 – d5
2. c2 – c4 d5xc4
3. e2 – e3 b7 – b5?
4. a2-a4 c7-c6
- 4.… a7 – a6 is useless, since after 5. a4xb5 Black cannot hit back with the a-pawn because of 6.Ra1xa8.
- 4.… Bc8 – d7 5. a4xb5 (otherwise Black can move 5.… c7 – c6) Bd7xb5 6. Bf1xc4! Bb5xc4 7. Qd1 – a4 +… and White gets a better position.
5. a4xb5 c6xb5
6. Qd1 – f3 and Black has to move in order to save the rook on a8 (6.… Nb8 – c6 7. Qf3xc6 + Bc8 – d7).
With 3. Ng1 – f3 b7 – b5 ?! is built up by 4. a2 – a4 c7 – c6 5. e2 – e3 with the threat of b2 – b3 pressure against b5.
