The Slav/Réti hybrid. Black plays solidly. Demuth recommends an early g3, Bg2, and 0-0, then the thematic d2-d4 break. The key idea: no rush. Grind the semi-Slav player who expects a slower game.
Chapter 13: The Old Indian / King’s Indian Delayed
Chapter 14: The English Defense (1…b6)
Chapter 15: The Polish / Unusual First Moves (1…a6, 1…h6, 1…Na6)
To convince you of the book’s quality, here is one key line against the Blumenfeld Gambit declined:
1.Nf3 d5 2.c4 d4 3.b4 g6 4.Bb2 Bg7 5.e3 dxe3? (better 5…Nc6)
6.fxe3 – White has a massive center, open f-file, and strong bishop on b2. Demuth gives 8 pages of analysis on this single variation.
The book includes over 400 diagrams and more than 300 complete games (some in notes). No “patch” can improve that.
