1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Bc4

5.Bd3 has been White's most popular choice in recent years.

5...Ngf6 6.Ng5 e6 7.Qe2 Nb6 8.Bb3 h6 9.N5f3 a5 10.a4 c5



11.Bf4!? Bd6

11...cxd4 12.0-0-0 Nbd5 13.Be5 Bd6 14.Nxd4 0-0 15.Ngf3 b6 16.Nb5 Ba6 saw Black with a reasonable position in Watson-Adams, London 1989.

12.Ne5 0-0 13.Ngf3 Nbd5 14.Bg3 Qc7 15.dxc5 Qxc5 16.0-0 b6 17.Rfd1 Ba6 18.c4 Rad8 19.Nd4



19...Bxe5

Black was probably worried about Nxf7.

20.Bxe5 Nb4 21.Nb5 Bxb5 22.cxb5 Rxd1+ 23.Rxd1



The white bishops may look impressive in this open position, but Black seems reasonably solid after, for example, Nbd5.

23...Rc8?

After this careless move, Black is suddenly losing.

24.Bxf6! gxf6 25.Bxe6! fxe6 26.Qxe6+



26...Kh8

26...Kg7 would have made things tougher, but White must be winning after 27.Rd7+ Kg6 28.Qf7+ Kf5 29.Qh7+ Ke6 30.g4.

27.Qxf6+ Kg8 28.Qe6+ Kh8 29.Qxh6+

White now has four pawns for the piece, but the most important feature of the position is Black's naked king.

29...Kg8 30.Qe6+ Kh8 31.h3

Threatening Qf6+ followed by Rd7.

31...Rf8 32.Qh6+ Kg8 33.Qg6+ Kh8 34.Qg3



34...Qc2?

Loses on the spot.

35.Rd4 resigns.

35.Rd4 Rf7 (35...Qh7 36.Rh4) 36.Rd8+ Kh7 37.Qg8+ Kh6 38.Rd6+ Kh5 39.Qg4 mate.
