abcdefgh

Plan principal. Jeu au centre (rupture e3-e4).

Atouts. Les Blancs s'appuient sur un contrôle dominant de f4 et e5 et un fou actif en g5.

Côté adverse. Un mauvais fou en c8.

En contrepartie. Le roi n'est pas encore à l'abri et plusieurs pièces dorment encore (le fou f1 et la tour h1).

Plans. Bd3 (Fou actif (mobilité 6), Développer f1 — 44 % des parties) ; h3 (Empêcher ...Bg4 — 20 % des parties) ; cxd5 (Capture en d5, Occuper le centre — 16 % des parties) ; c5 (Frapper le centre adverse — 9 % des parties).
