1. g1f3  1... g8f6  2. c2c4  2... c7c5  3. b1c3  3... e7e6  4. g2g3  4... b7b6  5. f1g2  5... c8b7  6. e1g1  6... f8e7  7. f1e1  7... f6e4  Avoiding the Hedgehog positions. 8. c3e4  8... b7e4  9. d2d3  9... e4b7  10. e2e4  10... b8c6  11. d3d4  11... c5d4  12. f3d4  12... c6d4  13. d1d4  13... e8g8  14. c1e3  14... d8c7  15. a1c1  15... c7c6  16. d4d2 Next Xiong goes for the throat at once with 16... f7f5  17. e3d4  17... f5f4 Objectively speaking, this should not be working but it makes the  games extremely sharp at once. 18. g3f4  18... e7d6  19. f4f5 Most likely a  blunder. 19... f8f5 Not only did White lose his extra pawn, but the rook is  positioned for the kingside attack. 20. b2b4 White needs to try and disturb the black bishops. 20... f5h5  21. h2h3  21... a8f8  22. e1d1 With the threat of Bd4xg7. 22... h5h3 Tempting,  but wrong. Now it is Giri's turn to fire. 23. d4g7 Now everything is hanging, but above all the black king is  less safe than his colleague. 23... h3h2  24. d2g5 Xiong was playing on seconds, and is under a decisive attack. A  lot of people would have thrown in the towel here... 24... f8f5 The  second rook goes wild. At the same square. 25. g5g4  25... g8f7  26. g7b2  26... d6f4  27. b4b5  27... c6c7  28. g4g7 The decisive moment of the match. It seems as White is mating,  but this is not the case. I am not sure White would have found the winning continuation even in a classical game though. 28... f7e8  29. b2f6  29... h2g2 Just in time. 30. g1g2
