1. d2d4  1... d7d5  2. c2c4  2... d5c4  3. g1f3  3... g8f6  4. e2e3  4... e7e6  5. f1c4  5... c7c5  6. e1g1  6... b8c6  7. b1c3  7... a7a6  8. d4d5 A critical move and only the sixth most played. The game now enters tactical territory that, judging by the quality and speed of play, was known to both parties. 8... f6d5 An accurate move. 9. c3d5  9... b7b5 This is Black's idea. 10. c4b3  Both sides were playing very quickly. 10... c5c4  11. b3c4  11... b5c4  12. e3e4  12... c8b7  13. f1e1  13... f8b4 Very precise and, again, played quickly. 14. c1g5  14... f7f6  15. g5d2  15... b4d2  16. d1d2  16... a8c8 It turns out that only this move is a novelty. 17. d5e3  17... d8d2  18. f3d2  18... c6e5  19. e1c1  19... e8e7  20. f2f3  20... c4c3  21. c1c3  21... c8c3  22. b2c3  Finally, we can pause to assess the position. White has an extra pawn, but the chances of a draw are considerable. 22... h8d8  23. d2b3  23... d8d3  24. e3d1  24... b7c6  25. g1f1  25... g7g5 A very good move, securing the knight on e5 and expanding on the kingside. 26. a1c1  26... c6a4  27. f1e1  27... g5g4  28. f3f4  28... e5c4
