14. f4 a5 15. f5 Bxb3 16. cxb3 a4 17. bxa4 Rxa4 18. f6?! Fritz suggest that white should secure his defend first with 18. b3 before playing f5-f6 for eg. 18.b3 Ra5 19.Kb1 now black can defense his queenside with Rc1 - Rc2 if nessecary, if not he can start attcking with f6! 18... gxf6 19. Kb1 probably here Svidler saw that the natural 19. gxf6? run into a strong exchange sacrifiece 19...Nef6 20. Bh6 Kh8! 21.Bxf8 Bxf8 when black has a simul attack on a2 and e4 ! 19...Qa8 20. Nc1 Nc5 21. Bxc5 dxc5 22. gxf6 Nxf6 23. Bc4 Kh8 24. Rhg1 Ra7 25. Qg5 Rg8 26. Qxe5 Qxe4+ 27. Qxe4 Nxe4 28. Bxf7 Rg7 29. Bd5 Nf6 30. Bc4 Rxg1 31. Rxg1 Bd6 32. h3 Re7 33. Rd1 Bc7 34.
