1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6 5.Nc3 This is an opening called the Scotch Game and it is the Four Knights Variation of it.
5...Bb4 6.Nxc6 bxc6 7.Bd3 0-0 8.0-0 d5 9.exd5 cxd5 10.h3 [10.Bg5 ]
10...c6 11.Qf3 Vishy is reluctant to give up his Black Squared Bishop just to double the pawns with 10. ..Bxc3 11.bxc3 because their are great big open spaces everywhere in this game and a Bishop will come in handy in them.
11...Bd6 12.Re1 h6 13.Bf4 Bxf4 14.Qxf4 Be6 15.Ne2 Qb8 16.b3 Qxf4 17.Nxf4 Rfe8? [17...Bd7 keeping his Bishop was much better with the open spaces I am surprised the World Champion allowed such a strategical mistake.]
18.Nxe6 fxe6 19.Bg6 Re7 20.c4 Nd7 21.Rac1 Nf8 22.Bd3 Kf7 23.cxd5 cxd5 24.b4 Nd7 25.Rc6 Nf6 26.a4 e5 27.f3 Rd8 28.Kf2 e4 29.fxe4 dxe4 30.Bc4+ Kg6 31.Ke3 Kh7 32.Rc5 Red7 33.a5 Rd2 34.Re2 Rd1 35.a6 Nd7 36.Rc7! [36.Kxe4?? Nxc5+ ]
36...Ne5 37.Be6 [37.Rxa7?? Nxc4+ ]
37...Kg6 38.Rxa7! Hao chooses the right pawn to take, Vishy must have been worried at this stage. [38.Kxe4? Kf6! 39.Bc8 Re8 40.Rf2+ Kg5 41.Rf5+ Kg6 42.Rxe5 Re1+ 43.Kd4 R1xe5~~ ]
38...R1d6 39.Ba2 the only safe square for the bishop. [39.Bb3? Rd3+ 40.Kxe4 Rxb3 41.Kxe5 Re8+ 42.Kd5 Rxe2-+ ]
39...Nc6 40.Rb7 Rd3+ 41.Kf2 Nd4 42.Bf7+ Kf5 43.Re1 Rd2+ 44.Kg1 Kf4 45.Bc4 g6 46.a7 Kg3 47.Bf1 The attack on the King looks strong but Hao has plenty of defenders and is threatening to bring in the cavalry in the shape of a Queen on a8.
48.gxf3 exf3 49.Rf7 Hao has enough to win, even without a Rook after 49...f2+ 50.Rxf2 Rxf2 moves such as b5 make the position hopeless as the two pawns cannot be stopped. So Vishy gave the Ghost. An Excellent game from Hao. The World Champion was beaten in this battle of economic and chess emerging nations. 1-0
