La case très forte dans la structure Karlsbad – Leçons vidéos et Cours d'échecs

La structure de pions Karlsbad est l’une des structures les plus fréquentes. Elle provient de plusieurs systèmes d’ouverture, le Gambit Dame variante orthodoxe, la Grünfeld-indienne, la Nimzo-Indienne et la Caro-Kann. En 1923, lors du grand tournoi de Karlsbad, plusieurs participants évitèrent la variante Cambridge-Springs en jouant 1. d4 d5 2. c4 e6 3. Cc3 Cf6 4. Fg5 c6 5. e3 Cbd7 6. Cf3 Da5 7. cxd5 exd5.

Les commentateurs baptisèrent alors cette structure asymétrique Karlsbad, système attractif pour les Blancs par la diversité des plans :

attaque de minorité sur l’aile Dame ;
attaque au centre par e3-e4 :
attaque sur l’aile Roi quand Blancs et Noirs ont fait le petit roque;
attaque sur l’aile Roi quand les Blancs ont fait le grand roque.

Dans le cadre de l’attaque de minorité par exemple les Blancs vont exercer une pression sur le pion c6 arriéré !
