Kasparov's net on Karpov's king is apt to be a classic

World Champion Gary Kasparov snapped out of the doldrums he had been mired in since his victory in the 16th game, regaining his magic touch to defeat former champion Anatoly Karpov in the 22nd game of their world championship match. The finish, in which Kasparov weaved a web to ensnare Karpov's king, is sure to find its way into anthologies. The victory, featured today, virtually clinched the championship, since it gave Kasparov an 11-to-10 edge in the match. Hence he needed but one draw more in his last two games to retain his title. Actually he drew both contests, winning the match 12 to 11.

The defeated former world champion may yet get another crack at Kasparov; but first, in February, he must meet and defeat 21-year-old Andrei Sokolov, who narrowly defeated Arthur Yusupov, 7 to 6 in the final challengers' match, recently concluded in Riga. Sokolov was behind by two points after four rounds, but pulled himself together to upset the more highly rated Yusupov. It will be interesting to see this rising star as he meets Karpov in play.

A. A reprise of the 12th game, when Karpov played 11. . . . P-B4 and soon achieved equality. Presumably he feared a Kasparov improvement. White now obtains some initiative and a spatial advantage, while Black's two bishops are not particularly adept at exploiting White's isolated QP.

B. It seems a mistake to take the knight out of reach of Q4, but Black is attempting to prevent an incursion of the white knight at K5.

C. The play on both wings is reminiscent of the best of Alekhine.

D. This weakening is atypical of Karpov, but the natural 22. . . . Q-N1; 23. Q-K3, Q-Q3; 24. N-K5 favors White, since 24. . . . R-K1 loses to 25. NxKBP!

E. Despite the paucity of material, Black has problems; largely because of White's powerhouse knight at K5. 30. . . . QxP?; 31. NxB, PxN; 32. QxP ch would cost Black his rook.

F. Black must abandon the RP, since 35. . . . R-N6; 36. R-R8ch! KxR; 37. NxP ch wins Black's queen.

G. The sealed move, and a knockout Karpov overlooked. The black king soon finds himself entombed, with White only needing a check to administer the coup de gr^ace.

H. 43. . . . R-Q6 also fails because of 44. R-N8, threatening 45. NxB and 46. R-R8 ch (44. . . . B-R2; 45. Q-N5 ch, QxQ; 46. PxQ ch nets White a piece).

I. Black has no adequate counter to the threatened 47. Q-K3 ch. A problem-like denouement.
