[January 18, 2018] Updated Opening Line from GM Dragan Paunović:
Queen’s Indian Defense, Classical Variation (incl. Tiviakov Defense)

[Line 217 : 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Bb7 5. Bg2 Be7 6. O-O O-O 7. Nc3]

Line 217 deals with Black’s various 7th move reactions, including the Tiviakov Defense (7… Na6), where White typically gets slightly preferable positions.

The other reaction (7… d5) usually (i. e. after 8. cxd5 exd5) transposes to a variation covered in Line 216 (though reached via a different move order).

By far the most popular and also the main line is 7… Ne4, with the idea to trade a pair of knights. Apart from 8. Bd2 (covered in our Line 218), White has two more choices that seem quite playable: to simplify the position with 8. Nxe4, or to play the more ambitious 8. Qc2. In either case, Black has reasonable chances to equalize.

[Diagram: White to Move] In the pre-computer days it was possible to win quite a few games using the same well-disguised opening trick, which can hardly happen today. About forty years ago, IM L. Neckár tricked (at least) three good players in the diagrammed position, playing as White. What did he play?
