Plan principal. Exploiter la case forte d5.

Atouts. Les Blancs s'appuient sur une majorité de pions à l'aile_dame (3 contre 2), la case forte d5, un avant-poste en d5, un fou actif en e2, la paire de fous et la colonne semi-ouverte d.

Côté adverse. Le pion arriéré d6, les fous enfermés en e7 et c8 et le roi resté au centre.

En contrepartie. Le roi n'est pas encore à l'abri et plusieurs pièces dorment encore (le fou c1 et les tours a1 et h1).

Plans. O-O (Mettre le roi en sécurité, connecter les tours) ; Bg5 (Clouer Nf6).
