1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... f7f5 Viktor Korchnoi used this delayed version of the Schliemann in one of his match games against Anatoly  Karpov. Back then it had a reputation as a dubious line, suitable for one  game only. This assessment will be hardly changed by this game, it seems. 5. d2d4  5... e5d4  6. e4e5  6... b7b5  7. a4b3  7... c8b7  8. e1g1  8... c6a5  9. f3d4  9... c7c5 So far, Tari was blitzing, while Duda was cautiously checking  his moves. On his next choice, the Polish GM spent more than 40 minutes. 10. d4f5 Kramnik predicted that this will be White's choice. 10... c5c4  11. b1c3 Three seconds were spent on this novelty. Duda  speeds up his development, hoping to get to the enemy king while it's  still in the center. 11... d8b6 Time for Tari to think. This is his best choice. The queen is out, ready to attack, and Black may castle long if needed. 12. c3d5  12... b7d5 The first long thought by Tari and a mistake at once. 13. d1d5  13... b6c6  14. d5d4  14... c6e6  15. f5d6 Opening the e-file as soon as possible. 15... f8d6  16. e5d6  16... g8f6 After this move, there is no way back. 17. d4c3 A double attack. Black fell short by a move and could not collect the trapped bishop. 17... e8g8  18. c3a5  18... f6g4  19. a5c3 Duda won material and consolidates his advantage. Tari's opening  experiment failed. 19... a8e8  20. c1g5  20... c4b3  21. c3b3 Two extra pawns are more than enough for the Polish GM to claim the win. 21... e6b3  22. a2b3  22... e8e2  23. f2f3
