1. e4 { Notes by George Botterill from the British Chess
Magazine. 'The player who shone most in the middle rounds was
Ray Keene. He had rediscovered the spirit of adventure and his
self-confidence had returned. In round five the new,
swash-buckling Keene really shattered Arnason.'} g6 2. d4 Bg7
3. Nc3 d6 4. f4 Nc6 5. Be3 Nf6 6. h3 {Fischer once won a game
with this ambitious plan, and it is certainly one of the more
dangerous ideas that Black has to face. (See Keen's game
against Penrose for something similar.)} 6...O-O 7. g4 e5
8. dxe5 dxe5 9. f5 gxf5 10. exf5 {! Fischer - Udovcic, Zagreb
1970, went 10 gxf5 Nd4 11 Nf3 c5 12 Bg5 +/-. But 10...Qxd1+ 11
Rxd1 Nd4 is known to be an improvement.} 10...Nd4 11. Bg2
11...Qe7 {!? Varying from 11...Ne8, which was tried without
success in van der Sterren - Goodman, Phillips and Drew
Knights 1980. Black is already offering a piece: if 12 g5 Bxf5
13 gxf6 Qxf6 with nasty threats.} 12. Qd2 Rd8 13. Qf2 h6
14. O-O-O c5 15. Nge2 a5 {!} 16. Ng3 a4 17. g5 hxg5 18. Bxg5
a3 19. Nd5 {19 b3 c4! helps Black. But Ray thought that 19 Nh5
was stronger.} 19...axb2+ 20. Kb1 Rxd5 {! This obliges White
to trade in his important dark-squared bishop, because 21 Bxd5
Qd6 would win for Black.} 21. Bxf6 Qxf6 22. Bxd5 Qa6 23. c3 c4
24. Qxb2 Nxf5 25. Nxf5 {? '25 Rdg1! is better, but Arnason was
scared of ...Ne3' (Keene).} 25...Bxf5+ 26. Ka1 e4 27. Rhg1 Bg6
28. Rg4 {? To answer 28...Bxc3? with 29 Rxg6+. But 28 Rg3 was
a better defence.} 28...e3 {!} 29. Rxc4 Re8 30. Qxb7 e2
31. Re1 Qxc4 {!! This temporary queen sacrifice annihilates
White's resistance.} 32. Bxc4 Bxc3+ 33. Qb2 Bxe1 34. Bxe2 Bg3
{! 'White is quite helpless against the threat of 35...Be5. A
truly beautiful finish. But beware of imitating such risky
play.' 'Keene continued to live dangerously and give rich
entertainment. Then in round eight came another brilliancy,
this time a double exchange sacrifice against Ligterink.'
