1. Nf3 { Notes by Raymond Keene. } f5 2. d4 Nf6 3. g3 g6
4. Bg2 Bg7 5. O-O O-O 6. c4 d6 7. d5 c5 8. Nc3 Na6 9. Rb1
{Fortunately for me, I had forgotten the 'theoretical'
continuation: 9 Ne1 Rb8 10 Nc2 Nc7 11 a4 b6 12 Rb1 (Korchnoi -
Tal, Candidates' match, 1968), which leads to a good position
for Black. The text prepares b2-b3 followed by transposition
into a kind of Panno King's Indian where Black has the extra
move ...f7-f5 - one that is both unaesthetic and seriously
weakening.} 9...Nc7 10. b3 a6 11. Bb2 b5 12. e3 {In order to
transfer the queen's knight to e6 via e2 and f4. With this
move White also intends to rule out the possibility of
combinations for Black involving ...Rb8 ...bxc4 ...f5-f4 and
...Bf5.} 12...Rb8 13. Ne2 Bd7 {This is rather stereotyped. If
Black is going to fight against White's strategic idea, he
must play 13...e5!, e.g. 14 dxe6 Nxe6 15 Nf4 Nxf4 16 exf4 Bb7,
and Black can generate some piece activity to compensate for
his dubious pawn structure and diseased central squares.}
14. Bc3 {! A key move. After this there are no more
difficulties for White - if pressed for a judgement, I would
be inclined to claim that Black is already strategically
lost. The only hope I saw for my opponent lay in the manoeuvre
...b5-b4 followed by ...a7-a5-a4-a3 (if allowed) and then a
king march from g8 to the queen's wing. When I suggested this
after the game Ree seemed unimpressed, but we could find
nothing better for Black in our post mortem analysis.}
14...Na8 {I could not understand this move.} 15. Ng5 Bh6 {Or
15...h6 16 Ne6 Bxe6 17 dxe6 when Black's king's wing is
isolated from his defensive pieces and White's bishops sweep
the board.} 16. h4 bxc4 {Sheer desperation - since Black must
ultimately lose control of the b-file. However, if 16...Bxg5
17 hxg5 Ne4 then 18 Ba1! followed by Qd2, with unpleasant
threats on the long dark diagonal.} 17. bxc4 Rxb1 18. Qxb1 Qb6
19. Qc2 Rb8 20. Nf4 Nc7 21. e4 {The final mopping up operation
begins. One can see at a glance just how bad Black's position
is.} 21...Bg7 22. e5 {Also strong is 22 Re1.} 22...Ng4
23. exd6 exd6 {23...Qxd6 is of much more use to Black's king
but does not do much for his pawn formation, which is
sufficiently shattered to guarantee a loss.} 24. Bxg7 Kxg7
25. Re1 Ne5 26. Nd3 Re8 {26...Nxd3 allows 27 Re7+ etc., while
if 26...Qa5 then 27 f4! wins.} 27. Qc3 Kg8 28. Nxe5 dxe5
29. Rxe5 Rxe5 30. Qxe5 h6 31. d6 1-0
