Nf3 d5 4. g3 Bb4+ 5. Bd2 Be7 6. Bg2 c6 7. Qc2 O-O 8. h4!? { Huston needs to win and he goes for a trendy line to take Guo out of mainstream theory. } 8... Nbd7 9. Nc3 dxc4 10. e4?! { A very natural move, but it weakens the d3-square, which allows Guo to play a strong pawn break. } (10. Rd1 a5) 10... e5! { A pawn "sacrifice", but it is very natural. The c5-square will be opened for the knight to reach d3, and the pawn on e5 will need defending. } 11. dxe5 Ng4 12. Bf4 Qa5?! (12... Nc5! { was even stronger } 13. O-O Nd3 14. Nd1 b5 { and Black's pieces are clearly more active. The downside of 8. h4 is starting to show. }) 13. e6?! { Huston goes for activity to try and mend his weakened position, but this doesn't quite work. } (13. O-O Nc5) 13... fxe6 14. Qe2 Nc5 15. O-O Nd3 16. Bd2 Qc7 (16... Qh5! 17. Nh2 e5 18. Bf3 Rxf3! { and White will have no counterplay: } 19. Qxf3 Be6 $17) 17. e5 Ngxe5 18. Ng5 h6 19. Nge4 b5 20. f4 Nf7 21. b3 b4 22. Na4 Ba6 { Guo has a completely winning position by now and the only thing left is to bring the rest of the pieces. } 23. Qg4 Qd7?? { Giving away all of the advantage! } (23... Nd6! 24. Qxe6+ Kh8 25. Qg6 Nf5 { and Black is winning because the attack is stalled and the queen is almost trapped. }) 24. Be3 c3 25. Kh2?? { Too slow. } (25. Rfd1! Qe8 26. Nec5 Nxc5 27. Nxc5 Bc8 28. Be4 { and White has a developing initiative on the weak light squares, but Black's advanced passer keeps him in the game }) 25... Nde5 26. fxe5 Bxf1 27. Rxf1 Nxe5 28. Rxf8+?! (28. Qe2 Qd3) 28... Rxf8 29. Qh5 Rf5 30. Qe2 Qd3! { With the forced queen trade, Guo goes into an endgame where he'll have no trouble converting. } 31. Qxd3 Nxd3 32. Naxc3 bxc3 33. Nxc3 Bc5 34. Bd2 Bb4 35.
