Main Line

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 c5 5. Bd3 Nc6 6. Nf3 Bxc3+ 7. bxc3 d6

Overview

A flexible Nimzo-Indian system where Black plays ...c5, ...Nc6, ...Bxc3+, and ...d6 — committing to a closed center with a pawn chain on d6 and e5 rather than the classical ...d5 break. After 7.bxc3 d6, Black's plan is ...e5, ...Nh5/Re8, and a slow positional squeeze of White's doubled c-pawns. Named after German grandmaster Robert Hübner who used the line in his 1971 Candidates Match against Tigran Petrosian. A reliable Black system that limits sharp theory while keeping all the structural advantages of the Nimzo-Indian.
