Les Noirs exploitent la case f4 – Leçons vidéos et Cours d'échecs

La case f4 (et f5 pour les Blancs) sont des cases assimilées fortes lorsque les coups e4 pour les Blancs et e5 pour les Noirs sont joués et vous le conviendrez assez souvent ! Ces deux cases sont assimilées fortes car elles ne peuvent être contrôlées que par g6 pour les Noirs et g3 pour les Blancs ce qui provoquerait des faiblesses sur les cases f6 et h6 pour les Noirs et h3 et f3 pour les Blancs ! Cf le diagramme ci-dessous.

Pour information la case f5 est appelée aussi la case et le cavalier Kasparov tant il a gagné avec cette case dans l’espagnole notamment !

Dans la variante d’échange dans le système O cette case f4 donc est souvent exploitée, une case structurelle dans le sens où une pièce et notamment le cavalier y est aussi fort que difficilement délogeable tant la poussée g3 serait affaiblissante pour les Blancs.

Cf4 avec la poussée g5
