1964: Unfinished symphony
In sixteen games against ARB I managed only two wins. The one I give below was particularly pleasing since it brought me the Devon County championship for 1964. — DJR
1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 c5 7. Bc4 Bg7 8. Ne2 Nc6 9. Be3 cxd4 10. cxd4 O-O 11. O-O Na5 12. Bd3 b6 13. Qd2 Bb7 14. Rac1 Qd7
So far standard manoeuvres for this variation, in which White tries to attack in the centre and on the King's-side, while Black relies on his Queen's-side majority for an endgame advantage.
15. Bh6 Rfc8 16. Bxg7 Kxg7 17. d5 Rxc1 18. Rxc1 Rc8 19. Nd4 Rxc1+ 20. Qxc1 Qc8
21. Qg5 White's attack shouldn't succeed against the best defence, but this looked the most promising way to play for a win.
21...Qc3 Black's threat, apart from attacking both Knight and Bishop, is of course Qe1+ (or Qa1+) followed by ...Ba6
Expecting 22... Kg8 . While I was wondering what to play after this obvious reply, Black blundered.
22...Kh8?? 23. Qh6 1-0
A sudden collapse — but what would have been best for White after ...Kg8? I still don't know. Perhaps a computer could give the answer!

[David Regis adds: Fritz offers variations after 22...Kg8:
[23. Bf1! f6 [23...Qc7 24. f4 f6 25. Qg4 Kf7+/= ] 24. Nxe7+ Kf7 25. Qh6 Kxe7 26. Qxh7+ Kd6 27. Qxg6+/= ]
[23. Nh6+?! Kf8 24. Qf4 f5 25. Bf1 Qd4=/+ ]
[23. Qg3?! Kf8 24. Qb8+ Bc8 25. Nd4 Qe1+ 26. Bf1=/+ ]
[23. Nxe7+ Kf8 24. Bf1 f6= is similar to lines above]
