d6 10. Qd3 Rb8 11. Bd2 a6 12. a4 Be6 13. Rac1 Ng4 {Commencing
a mistaken knight tour which eventually leaves White in
control of the centre. Better is 13...Qd7 followed by ...Bh3
as Kaplan played against Stein at Hastings earlier in the
year, although I feel that this too should eventually run out
in favour of White.} 14. b3 Ne5 15. Qb1 Nc6 16. Rfd1 Re8
17. Nd5 Nd4 18. Qd3 Bg4 19. f3 Bd7 20. e3 e6 {? Ingenious but
ultimately incorrect. Of course, if White were to play 21 exd4
then 21...exd5 would leave Black with plenty of
compensation. Unfortunately, White has a far superior line at
his disposal, hence it would have been more sensible to play
20...Bf5! 21 e4 Bd7 and if 22 Be3 then 22...e5, holding the
flanking blows ...b7-b5 and ...f7-f5 in reserve.} 21. Nb4 {!}
Nf5 22. Kh1 {An insurance against accidents along the g1-a7
diagonal and a generally useful safety precaution. Black now
has to find an answer to the impending e3-e4.} 22...a5 {!?}
23. Nc2 d5 {!? Black continues in the ingenious, if slightly
unsound, vein that has hitherto characterised his
play. Objectively speaking, White should probably accept
Black's sacrifice with 24 cxd5 exd5 25 Qxd5 Be6 26 Qb5 and
Black would be hard put to it to justify his bold
play. However, I finally resolved to pursue a calm positional
course and ignore Black's demonstration.} 24. e4 dxc4 25. Qxc4
{Not 25 bxc4 Bxa4! 26 Qxd8 Rbxd8 27 exf5 Bb2 and Black wins.}
25...Ne7 26. Qd3 {! This quiet retreat leaves Black with
unsolvable problems. White threatens both Bg5 and Be1 and in
some lines Bf4, while if Black moves his queen's bishop he
would lose his a-pawn after the exchange on d8. Black's
solution is once again ingenious, but not fully satisfactory.}
26...e5 27. Bg5 {I also looked at 27 Be1 Be6 28 Qb5 Qc8 29
Bxa5 but rejected it in favour of the text which seemed more
clear-cut in its effect.} 27...f6 28. Qxd7 {After 28 Bh3 Bxh3
29 Qc4+ Kh8 30 Rxd8 Rbxd8 I felt there would still be
considerable technical problems to overcome.} 28...Qxd7
29. Rxd7 fxg5 30. Ne3 Nc6 31. Bf1 Red8 32. Rxd8+ Rxd8 33. Bc4+
Kh8 34. Bd5 Nd4 {Black cannot allow the exchange on c6 which
would shatter his pawns beyond repair, but now White's rook
penetrates to the seventh, after which, at best, both Black's
queenside pawns are doomed.} 35. Rc7 Rb8 36. Nc4 Nxb3 {Pure
desperation, but if 36...b6 37 Nxb6!} 37. Nd6 Nd4 38. Nf7+ Kg8
39. Nxg5+ Kh8 40. Nf7+ Kg8 41. Nxe5+ Kh8 42. Nf7+ Kg8 43. f4
