myself.} 9...h6 10. Qe2 Qc7 {Black prepares to castle
queenside. Another possibility is the immediate 10...b6.}
11. dxc5 {A major decision, since White's doubled c-pawns now
look very sick. However, White does now have time to direct
his knight towards d5, which he does not have after the
premature 9 dxc5.} 11...dxc5 12. Nh2 {In some ways a
surprising move, but the knight is en route to the dominating
square d5. } 12...b6 13. Nf1 Ba6 14. Ne3 O-O-O 15. Nd5 Qd7 {Of
course Black does not capture voluntarily on d5. He hopes, in
the long run, to annex White's pawn on c4.} 16. O-O Ne8

launch a powerful attack with moves like 20 Rb3 followed by
Ra3, Be3 and Rb1. There are many sacrificial possibilities
against a black knight on a5 or pawn on c5. 19...Qd6, though
forced, temporarily blocks the journey of Black's king's
knight to this desirable square.} 20. Be3 {Even here a
possible improvement is 20 Rb3 Na5 21 Ra3 planning an exchange
sacrifice on a5, followed by a concerted attack on c5 based on
moves such as Be3 and Qf2.} 20...Na5 21. Rb2 Rd7 22. Rfb1 Rb7

intending ...Ka8 and ...Rb8, White does not need to mark time
but could thrust forward his kingside pawns.} 29. Rb5 {! An
exchange offer to blunt Black's pressure against the
c4-pawn. An added bonus is the opening of the a-file.}

a fresh exchange sacrifice which disables Black's
position. Correct is 32...Qd8.} 33. Rxa5 {!} bxa5 34. Qxa5 Qf8

is forced.} 35. Qa6 Ne8 {An improvement is 35...Rd7 36 Qa3 Nb7
37 Be2 Qf7! although at this point it is not so easy to grasp
that Be2-h5 must be stopped.} 36. Qa3 Qd6 37. Be2 {! On
material criteria alone Black is 28 points to 25 points ahead,
and should win. But White's sacrifices have turned a static
situation into a dynamic one, and have also unbalanced Black's
mental equilibrium. Now the threat of Bh5 suddenly leaves
Black hamstrung. Ligterink now decides to jettison excess
baggage.} 37...Ka8 38. Bh5 Nc7 39. Bxc5 39...Nxb5 40. Bxd6

41...a5.} 42. Bb4 Rxe4 43. Bf3 Rc4 44. Ne3 e4 {? A time

Black stunned. My opponent could not cope with the quick-fire
changes from an apparent technical win to a running
battle. 'In accordance with an earlier decree the tie between
Keene, Seirawan and Miles also had to be resolved. Finally
recourse had to be made to SOS and on this second count Ray
Keene came out ahead and was duly declared the Lloyds Bank
