1. g1f3  1... d7d5  2. b2b3  2... c8f5  3. c1b2  3... e7e6  4. d2d3  4... h7h6  5. b1d2  5... g8f6  6. g2g3  6... c7c5  7. f3e5  7... b8d7 A mechanical, obvious move and a novelty. And... a  mistake. 8. e2e4  8... f5h7  9. e5d7  9... d8d7  10. f1g2 With simple moves Wei forced Black on the defensive  and now it is not clear how is he going to finish the development. 10... d7d8 A strange-looking move, but were there any reasonable  alternatives? 11. e4d5 White naturally wants to open up the game as he is much  better prepared for that. 11... e6d5  12. d1e2 Now White hampers the enemy pawn structure and leaves his king  in the center. At top level, this is a miniature. 12... f8e7  13. b2f6  13... g7f6  14. e1g1  14... h7f5  15. a1e1  15... f5e6  16. e2h5  16... d8d7 All natural as well as White's next move. 17. e1e6 Played after mere 14 seconds of thought! Indeed, this is not even a sacrifice as White instantly picks up two pawns for the exchange. 17... d7e6  18. g2d5  18... e6d7  19. d5f7  19... e8d8  20. f1e1 Next White simply strengthens the position of his pieces. There  are way too may weak spots for Navara to cover them all. 20... d8c7  21. f7e6  21... d7d8  22. d2c4  22... a7a6  23. e6d5  23... a8a7  24. h5f7  24... h8e8  25. d5f3  25... b7b5 This loses prosaically, but there was no escape anyway. 26. c4a5
