Atouts. Les Blancs s'appuient sur les cases fortes b5, e5 et g5 et la paire de fous.

Côté adverse. Le fou enfermé en c8 et le roi resté au centre.

En contrepartie. Le roi n'est pas encore à l'abri et plusieurs pièces dorment encore (les fous c1 et f1 et les tours a1 et h1).

Plans. O-O (Mettre le roi en sécurité, connecter les tours) ; e4 (Centre d4+e4, menace e5, libère Bf1) ; Bg5 (Clouer Nf6) ; h3 (Empêcher ...Bg4).

Atouts. Les Noirs s'appuient sur la case forte e4, un fou actif en b4 et la paire de fous.

Côté adverse. Les fous enfermés en c1 et f1, le roi resté au centre et une pièce en prise (le pion en c4).

En contrepartie. Le roi n'est pas encore à l'abri et plusieurs pièces dorment encore (le cavalier b8, le fou c8 et les tours a8 et h8).

Plans. O-O (Mettre le roi en sécurité, connecter les tours) ; ...Bd7 (PRIORITÉ: libérer le Bc8 (...Bd7, b6+Bb7, ...Bg4, ...Bf5)) ; ...Nbd7 (Développer Nb8) ; ...Bg4 (Clouer Nf3) ; ...e5 (Rupture).

D38 — D38 – 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Bb4 5…. – Queen’s Gambit Declined: Ragozin Defense

Eval: +0.37

La Défense Ragozin — 4…Fb4. Au lieu du classique …Fe7 ou …c6, les Noirs clouent immédiatement le Cc3. C’est la contribution de Viacheslav Ragozin à la théorie du QGD. Le Fb4 paralyse le Cc3 et empêche e4 — la rupture centrale blanche est neutralisée d’emblée.

Eval (+0.37). Les Blancs ont un léger avantage mais les Noirs ont un contre-jeu actif. La Ragozin est le choix de Caruana, MVL, Nepomniachtchi — c’est une défense moderne et ambitieuse.

Plans des Blancs

Fg5 — double clouage : Répondre au clouage par un clouage. Le Fg5 cloue le Cf6, le Fb4 cloue le Cc3. Position très tendue avec des pièces clouées des deux côtés.

cxd5 — simplifier : Échanger au centre pour résoudre la tension. Après exd5, le Fb4 n’a plus de cible si le Cc3 est libre.

Plans des Noirs

…0-0 + …c5 — contre-attaque : Roquer puis frapper d4. Le Fb4 cloue le Cc3 et les Noirs ouvrent le centre avant que les Blancs ne se consolident.
