Atouts. Les Blancs s'appuient sur la case forte d5, un fou actif en a4 et la paire de fous.

Côté adverse. Les fous enfermés en c8 et f8 et le roi resté au centre.

En contrepartie. Le roi n'est pas encore à l'abri et plusieurs pièces dorment encore (le cavalier b1, le fou c1 et les tours a1 et h1).

Plans. O-O (Mettre le roi en sécurité, connecter les tours) ; Nc3 (Développer Nb1) ; d3 (Libérer Bc1) ; h3 (Empêcher ...Bg4).
