1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. d2d4 Clever strategy. For the decisive blitz game,  Nepomniachtchi chooses an opening that served him well all his life-the  Scotch. When one knows all the subtleties in a positon, he can quickly  orientate himself in the most complex situations. 3... e5d4  4. f3d4  4... g8f6  5. d4c6  5... b7c6  6. e4e5  6... d8e7  7. d1e2  7... f6d5  8. h2h4  8... a7a5  9. c2c4  9... c8a6 One of the ways to fight the Scotch. Black increases his  development advantage but takes positional risks. His light pieces on the  queenside might remain locked behind the solid white pawn chain. 10. b1d2  10... d5b6  11. h4h5  11... e7e6 Not the most convincing reply. 12. h5h6 This not only weakens Black's positon but also opens the road for  the white rook. 12... g7h6  13. b2b3  13... e8c8  14. c1b2  14... f8g7  15. e1c1  15... h8e8  16. f2f4  16... f7f6 That is a blunder, but what else? 17. d2e4 With the unstoppable threat of a knight fork. 17... f6e5  The best chance under the circumstances. 18. e4c5  18... e6f5  19. c5a6 Nepomniachtchi won a piece, but he faces  difficulties trying to bring it out of the danger zone. 19... e5f4  20. e2d3  20... g7b2  21. c1b2  21... f5e5  22. d3c3  22... c8b7
