"...I was impressed by this game as Petrosian must have been, as he got crushed." -- FISCHER.

Nimzo-Indian style (B7c)

Langeweg - Korchnoi, Amsterdam, 1976

1.Nf3 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 0-0 5.a3 Bxc3 6.Qxc3 b6 7.g3 Bb7 8.Bg2 d5 9.d4 dxc4 10.Qxc4 Bd5 11.Qc3 Nbd7

"The game had several critical points.

At move 11 I was threatening to equalise by ...c5 so my opponent played the ambitious b2-b4. It caused White difficulties because of his under-development and gave the Black pieces space for active play."

12.b4 a5 13.b5?! c6 14.bxc6 Rc8 15.0-0 Rxc6 16.Qe3 Qa8 17.Bd2 b5?!

"Imprecise: now the b-Pawn is a weakness.

I had to exchange one of White's Bishops in order to obtain chances of advancing the Queen's-side Pawns and give myself the better chances in the ending. For the moment the position had become unclear."

18.Rfb1 Rb8 19.Ne1?! Bxg2 20.Nxg2 Ne4!

"Siezing the initiative: White is taken aback."

21.Qd3 Rd6 22.Be3?! Ne5 23.Qc2? Rc8 24.Qb3 Nc4 25.Rc1 Rdc6 26.Qxb5 Nxa3 27.Qa4 Nc2 28.Rab1 Rc4 0-1

Audacious, even arrogant. Gik had published some analysis on this line ... for White against the Sicilian, but mostly people weren't convinced even in that situation. Nowadays of course the theme has become well-known.

Of course, Black is not forced to win on the King's-side; he has a very good version of the Nimzo-Indian!

16. Nb2 Qf7 17. Rd1 Nxc4 0-1

Smart - Hodgson [A21] England, 1984

  White need not submit to the doubling of the c-Pawns in this line.
