(1) Carlsen,Magnus (2484) - Ernst,Sipke (2474)
Corus C Wijk aan Zee NED, 2004
[GM Lubomir Kavalek/The Huffington Post]

21.Bxh6! gxh6 22.Rxh6+!! This gorgeous rook sacrifice opens the h-file and is based on a vulnerable seventh rank.

22...Nxh6 23.Qxe7 Nf7
(The only reasonable way to defend against 24.Qh7 mate.)

[Creating a mating attack. Carlsen's move improves on the game Almagro Llanas,P (2375)-Gustafsson,J (2570), Madrid 2003, in which after 24.Qf6+ Kg8 25.Rh1 Nh6 26.Qe7 Nf7 but after 27.Qf6 (White still wins with 27.Rh5! Kg7 28.gxf7 Qa6 29.Qe5+ Qf6 30.Qg3+ Qg6 (30...Kxf7 31.Qc7+ Ke6 32.Re5++- ) 31.Rg5+- ) 27...Nh6 28.Qe7 Nf7 a draw was agreed.]

[After 24...Qb6 25.Qe5+! Kh7 26.Rh1+ Qh6 27.Rxh6+ Kxh6 28.Qf6+ white wins, for example 28...Kh7 (28...Kh5 29.f3 ) 29.c3! cxd4 30.g4 d3 31.g5 d2 32.Qh6# ]

[A good way to win, but better is 25.Qe5+! Kxf7 26.Rd3 for example: 26...Rxd4 (26...Rg8 27.Rf3+ Kg6 28.Qf6+ Kh5 29.Rh3+ Kg4 30.f3# ) 27.Rf3+ Kg6 28.Rg3+ Kh6 29.Qg7+ Kh5 30.Qh7# ]

[Allowing a nice mate. Black could have prolonged the game with 25...Qb6 but white should win after 26.Rg3+ Qg6 27.Rxg6+ Kxg6 28.d5+- ]

26.Rg3+ Rg6 27.Qe5+ Kxf7
[27...Kh7 28.Qh5+ Rh6 29.Qf5+ Kh8 30.Qe5+ Kh7 31.Qg7# ]

28.Qf5+ Rf6
[After 28...Ke7 29.Re3+ wins. Now the game ends with an epaulet mate.]

29.Qd7# 1-0
