Grünfeld Defense: Russian System
Main Line
1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Qb3
Overview
White's most ambitious anti-Grünfeld treatment. With 5.Qb3, White attacks Black's d5-pawn before recapturing on c3 — forcing 5...dxc4 6.Qxc4 and reaching a position where White builds a powerful e4/d4 center while Black plays for ...c5, ...Nc6, and ...Bg4 counterplay. The Hungarian Variation (7...a6 + ...b5), Smyslov Variation (7...Bg4), Prins Variation (7...Na6), and modern Main Line (7...Nc6 8.Be2 e5) all branch from move 7. Used by Anatoly Karpov against Garry Kasparov in their epic 1986–1990 world championship matches — Karpov scored multiple wins with the Russian System and it remains a top theoretical battleground today. Modern proponents include Vladimir Kramnik, Sergey Karjakin, and Ding Liren.
