1. e2-e4 e7-e6 2. d2-d4 d7-d5 3. Nb1-c3 Ng8-f6
The classical system is a variant of the French defense of the game of chess . In the ECO codes , the variant is classified under the keys C12 to C14.
This variant was the most common variant of the French defense at the end of the 19th and beginning of the 20th century, especially the former vice world champion Siegbert Tarrasch used it often. The first world chess champion, Wilhelm Steinitz , dealt extensively with 4. e4 – e5.
It arises after the trains:
1. e2-e4 e7-e6 2. d2-d4 d7-d5 3. Nb1-c3 Ng8-f6
Possible sequels:
4. e4 – e5 (Steinitz variant) Nf6 – d7 5. f2 – f4
(5. Qd1 – g4 is the Gledhill attack suggested by the English chess player Walter Gledhill . In 1901 he published analyzes on this in British Chess Magazine . Emanuel Lasker commented on these analyzes. After the standard answer 5.… c7 – c5, 6. d4xc5 is an attempt at rehabilitation. )
c7-c5
- 6. d4xc5 (mostly drawn by Steinitz)
- 6. Ng1-f3 Nb8-c6 7. Bc1-e3
- 7.… a7 – a6 and 8.… b7 – b5
- 7.… c5xd4
- 7.… Qd8 – b6 8. Nc3 – a4 Qd8 – a5 + 9. c2 – c3 c5 – c4 10. b2 – b4
Because White himself blocks his c1 bishop to the 'worse bishop' here, 4. Bc1 – g5 was preferred in the 20th century. It was not until the 1990s that the Rubinstein variant 4. e4 – e5 was played more often again.
4. f2 – f3 ?! (Attempt to switch to the Blackmar-Diemer-Gambit ) d5xe4 (4.… c7 – c5) 5. Bc1 – g5 e4xf3 6. Ng1xf3 (Blackmar-Diemer-Gambit, Euwe defense)
4. Lc1-g5
- 4.… d5xe4 (goes into the Rubinstein variant)
- 4.… Bf8 – b4 ( MacCutcheon variant ; sharp, risky game)
- 4.… Bf8 – e7 (classic continuation)
The classic 4. Bc1 – g5 Bf8 – e7 often leads after 5. e4 – e5 Nf6 – d7 6. Bg5xe7 Qd8xe7 to blocked pawns in the center, in which White usually seeks the initiative on the kingside, while Black puts pressure on White's central pawn , typically with the moves ... c5 and ... f6, seeks counterplay.
White supports his center with 7. f2 – f4 in order to keep Black narrowed.
A serious problem for the player with the black pieces is the so-called 'bad bishop' on c8, which sometimes does not develop until the endgame, which at a higher level of play often leads to a loss of the game. White was able to dispose of his somewhat 'worse bishop' against the better of the black bishops. As a white man, Tarrasch delivered sample games in 1885 in Hamburg against J. Noa and in 1912 in San Sebastian against Richard Teichmann .
The Alekhine Chatard attack is recommended for attacking players 4. Bc1 – g5 Bf8 – e7 5. e4 – e5 Nf6 – d7 6. h2 – h4. This pawn can Ke8xe7 be refused on the 6th ... a7-a6 or 6. ... c7-c5 7. Lg5xe7.
