1. Nf3 { Notes by Raymond Keene. } f5 {In 1974 the Dutch
Defence had enjoyed a new wave of respectability, mainly in
those lines where Black fianchettoes his king's bishop.} 2. d4
Nf6 3. g3 g6 4. Bg2 Bg7 5. O-O O-O 6. c4 d6 7. d5 {! Favoured
by Huebner, Petrosian and Korchnoi. 7 Nc3 Nc6 8 d5 Ne5 9 Nxe5
dxe5 doesn't promise too much for White.} 7...c5 {Against
7...c6 White has 8 Nc3 e5 9 dxe6 Bxe6 10 Qd3¿ (see game
63). The text leads to a kind of Yugoslav King's Indian where
Black has the extra move ...f7-f5 which gives him increased
central control, but which could also be construed as a
loosening of his kingside.} 8. Nc3 Na6 9. Rb1 Rb8 {Less good
is 9...Nc7 10 a4 a6 11 b4! +/- (Petrosian).} 10. b3 Nc7
11. Bb2 a6 {A superfluous preparatory move. He could have
played 11...b5 at once, since White would hardly contemplate
12 cxb5? After 11...b5 I would have played 12 Qc2 bxc4 13 bxc4
Ba6 14 Nd2 with a slight edge.} 12. e3 b5 13. Ne2 13...a5 {A
new move. I had reached this identical position on three prior
occasions. Keene - Hindle, English Counties' Team Ch. 1970,
continued 13...Qe8?! 14 Bc3 b4 15 Bb2 h6 16 a3 bxa3 17 Bxa3 g5
18 b4 cxb4 19 Bxb4 Qh5 20 Ned4 f4 21 exf4 gxf4 22 Nc6 +/-,
while Keene - Ree, Paignton 1970 (game 20), saw 13...Bd7 14
Bc3 Na8 15 Ng5 while also not bad is 15 Nf4 as in Keene -
Matulovic, Siegen Olympiad 1970.} 14. Nf4 a4 15. h4
{Threatening Ng5 in conjunction with h4-h5, so Black must
release the tension on the opposite wing in order to
inaugurate instant counterplay.} 15...axb3 16. axb3 bxc4
17. bxc4 Rb4 18. Nd2 Ba6 19. Qc2 {Here I declined the offer of
a draw.} 19...Qd7 20. Nd3 Ra4 21. Ra1 Rxa1 22. Rxa1 Rb8
23. Bc3 Qc8 24. Nf4 Nd7 25. Bxg7 Kxg7 26. Qc3+ Kg8 27. e4 {The
same advance as in the Ree game, although the circumstances in
this case are by no means so favourable. Black's hold on the
central dark squares gives him definite hope of retaliation.}
27...Ne5 28. Nd3 {28 Bh3 looks most attractive, but it fails
to 28...Qb7! 29 exf5 Qb2 or 29 Rb1 Qxb1+! 30 Nxb1 Rxb1+
followed by ...fxe4 or ...Bxc4 and Black has a powerful
initiative plus adequate material compensation for the queen.}
28...Nxd3 29. Qxd3 Qf8 {Coming round to reinforce the dark
squares.} 30. Re1 Qf6 31. exf5 gxf5 32. Bh3 f4 33. Ne4 {? With
both sides short of time, the play loses its cohesion. Correct
was 33 Qe4! and if 33...fxg3 34 fxg3 Qc3 (which I feared)
simply 35 Qf4! +/-.} 33...Qd4 34. Qxd4 cxd4 35. Bf1 Rb4
36. Nd2 Kf7 {He should have captured on g3, and next move I
should have captured on f4.} 37. Re4 fxg3 {!} 38. fxg3 d3 {!
The d-pawn clings to life by a miracle. If 39 Bxd3 Rb2!
threatening ...Rxd2 and ...Nxd5 exploiting the pin.} 39. Rf4+
Kg7 40. Rg4+ Kf6 {After the game Jansa advocated 40...Kh8, but
it doesn't look convincing after 41 Rd4.} 41. Rf4+ {The sealed
move. 41...Ke5 is impossible (42 Nf3 mate!) so Black must
retreat. It transpired that the Czechs had spent most of the
adjournment pause analysing 41 Bxd3, so the text enjoyed a
certain surprise value.} 41...Kg7 42. Kf2 {Many hours of
adjournment analysis convinced me that the forcing 42 Re4 did
not achieve much, so I decided to try this very quiet king
move as the possibility least likely to have been analysed by
my opponent.} 42...e6 43. dxe6 Nxe6 44. Rg4+ Kf6 {? Here
44...Kh8 really does draw, e.g. 45 Bxd3 d5 (threatening to
liquidate the queenside) 46 Bf5 Ng7! 47 cxd5? Rb2! or 45 Re4
Nc5 46 Rd4 Rb2! 47 Ke3 Rxd2 48 Kxd2 Nb3+ 49 Kxd3 Nxd4 50 Kxd4
Bb7! with a drawn ending. The pawn minus doesn't mean
anything, since White cannot successfully surround Black's
d-pawn.} 45. Bxd3 d5 46. Bxh7 dxc4 47. Ke3 {This is a win for
White who will soon annex the black c-pawn.} 47...Ra4 {After
47...Nc5 White plays 48 Rg6+ followed by Rc6, but not 48 Bg8?
c3!! 49 Rxb4 c2 50 Ne4+ Nxe4 51 Rb6+ Kg7 52 Rc6 Kxg8 53 Rxc2
Bb7 with excellent drawing chances for Black.} 48. Bd3 {!
Winning the pawn much earlier than anticipated. Black could
now have resigned - the more so after his next move.} 48...Ng7
49. Rg6+ {!} Kf7 50. Rxa6 Rxa6 51. Bxc4+ Re6+ 52. Kf4 Kf6
53. Bxe6 Nxe6+ 54. Kg4 Nc5 55. Kh5 Kg7 56. g4 Nd7 57. Kg5 Ne5
58. Kf5 Ng6 59. Nf3 Kh6 60. Kf6 Nf4 61. Nd4 {It was lucky for
me that there were no adjudications in international
tournaments!} 1-0
