The Tarrasch Defense is one of the closed games and is a sub-variant of the Queen's Gambit .

It is named after the German chess master Siegbert Tarrasch , who saw it as the only correct defense against the Queen's Gambit.

Each of its main variants begins with the following moves:

1. d2-d4 d7-d5 2. c2-c4 e7-e6 3. Sb1-c3 c7-c5

Often there is a black Isolani as in the main line after 4. c4xd5 e6xd5 5. Ng1 – f3 Nb8 – c6 6. g2 – g3 Ng8 – f6 7. Bf1 – g2 Bf8 – e7 8. 0–0 0–0 .

Black consciously accepts the weakening of his pawn position. In return, he receives free character development.

Black can avoid Isolani in the main line after 9. Bc1 – g5 or after 6. g2 – g3 with c5 – c4. The Swedish variant 6. g2 – g3 c5 – c4 is continued after 7. Bf1 – g2 with Bf8 – b4 8. 0–0 Ng8 – e7.

The fianchetto was introduced by Schlechter and Rubinstein .

One attempt at rebuttal is 5. d4xc5.

After 4. c4xd5 c5xd4 there is a secondary variation, the Schara-Hennig gambit . This is named after the Viennese chess player Anton Schara, who won a game against Grünfeld in 19 moves with it in 1918 , and after the German Heinz von Hennig , who introduced this variant into tournament practice in 1929 in Duisburg against Benzinger. However, there are preliminary games, namely Marshall against Howard, Sylvan Beach 1904 (white victory), and Viakhirev against Chepurnoff, Saint Petersburg, All-Russian Championship 1909 (black victory).

Tarrasch described the symmetrical variant 4. e2 – e3 Ng8 – f6 5. Ng1 – f3 Nb8 – c6 as the only correct continuation for White. Now after 6. c4xd5 taking it again with the knight Nf6xd5 would lead to an improved Tarrasch defense . 6. d4xc5 appeared in Rubinstein's Immortal game .

The Tarrasch Defense is particularly valued by types of players who prefer active puppet play to static elements. In world championship fights, the Tarrasch Defense was used by Boris Spassky and Garry Kasparov .
