　　11...Ra6! A very interesting piece sacrifice (12.Bxd5 Qxd5 13.Rxe7 Rg6 – with the threat of 14...Qxg2#) immediately after Karjakin's novelty, which the Ukrainian did not dare to accept. 12.Qh5 Nb4 13.Na3 Rg6 14.Bf4 b6 15.Qf3 Be6 16.Bxe6 fxe6 17.Qe4 Bd6 18.Bxd6 cxd6 19.Qxd4

　　White is a pawn up, but Black is calling all the shots. 19...Qg5 (once again the annoying threat of ...Qxg2#) 20.g3 Qf5 21.g4 h5 22.Re4 d5 23.Kh2 Qf3 24.Ree1 hxg4 25.Qe3 gxh3 26.Qxf3 Rxf3 27.Rg1 Rxf2+ 28.Kxh3 Rxg1 29.Rxg1 Nxc2 30.Nb5 Rf3+ 31.Kg4 Rxd3

　　White has ended up three pawns down and not a hope left to survive. 32.Nd6 Ne3+ 33.Kf4 Nc4 0-1.
