1. Nf3 { Notes by Raymond Keene. } Nf6 2. g3 g6 3. Bg2 Bg7
4. O-O O-O 5. c4 d6 6. d4 Nc6 {This and Black's next move
constitute the Panno Variation, which was then in fashion as a
method of meeting White's kingside fianchetto.} 7. Nc3 a6
8. d5 Na5 9. Nd2 c5 10. Qc2 Bd7 {? Black's best try for
equality would seem to be 10...Rb8 11 b3 b5 12 Bb2 Bh6 without
exchanging on c4.} 11. b3 b5 12. Bb2 Qb6 13. Nd1 Rfb8 {There
is a common misconception that the best way to handle this
type of position for Black lies in building up pressure on the
potentially open b-file. This is completely false, and many
games have been lost by Black through the misplacing of the
rooks on this file, while White gradually steamrollers through
the centre with f2-f4 and e4-e5. Against the configuration of
minor pieces adopted by White here (bishop - c3, knights - d3,
d2) Black's rooks are helpless since they are denied points of
entry. Meanwhile, Black's knight on a5 is beginning to look
ridiculous, and White's minor pieces are admirably placed to
support a central advance and transfer to the opposite wing.}
14. e4 bxc4 15. bxc4 Qd8 16. Bc3 Ne8 17. Nb2 Ra7 18. Nd3 e6
{Black must do something to avoid slow but sure extinction
after f2-f4, but a better method of achieving counterplay
would have been 18...Bd4. Now Black has weakened both his dark
squares and the base of his pawn chain, and White exploits
these factors by means of a temporary pawn sacrifice.}
19. Bxg7 Nxg7 20. e5 {! With the dire threat of Ne4.}
20...exd5 21. Bxd5 Bf5 22. Qc3 Bxd3 23. Qxd3 dxe5 24. Qe3 Qe7
25. Rfe1 Nf5 26. Qc3 {Now White's bishop has taken up a
commanding post on d5 whence it menaces the vulnerable f7
square, and Black is also obliged to return his extra pawn.}
26...Qc7 27. Rxe5 Nc6 28. Ree1 Nfd4 29. Nf3 {Contemplating a
trip to g5, hence ...} 29...Nxf3+ 30. Qxf3 Nd4 31. Qf6 Nc2
{Rather optimistic, but it is already too late to discover a
really satisfactory defence. The text does at least have the
virtue of removing White's dangerous bishop.} 32. Rab1 Rxb1
{And not 32...Nxe1? 33 Bxf7+! winning instantly.} 33. Rxb1 Nb4
34. Re1 Qd7 35. h4 {35 Rd1 threatening Bxf7+, as suggested by
team captain C.H.O.D. Alexander after the game, also wins
easily, e.g. 35...Qe8 36 Bb7!! and then Rd8. Now Black is
threatened with imminent mate following the further advance of
the h-pawn, so he is forced to give White a winning passed
pawn.} 35...Nxd5 36. cxd5 Ra8 37. d6 Qf5 {After the
alternative 37...Rd8 38 h5 Black has no defence against 39 h6;
the try 38...Qxd6? is met by 39 Re8+; 38...gxh5 by 39 Re5 or
39 Re7.} 38. Qe7 Qd5 39. d7 Rf8 {Losing at once - but if
39...Kg7 40 Qe8, 41 Qxa8, 42 Re8 etc. wins anyway.} 40. Qxf8+
