That amazing old warrior, Victor Kor- chnoi, has fought his way back into the Candidates' tournament by winning the third and final Interzonal in Zagreb. Final scores out of 16 possible were: Korchnoi (Switzerland) 11; Seirawan (USA) and Ehlvest (USSR) 10; these three qualify. Further scores were: Nikolic (Yugoslavia), Granda (Peru) and Noguieras (Cuba) 91/2; Torre (Philippines) 9; Polugaievsky (USSR), Einghorn (USSR), Pinter (Hun- gary) and Griinfeld (Israel) 81/2; Hulak (Yugoslavia) 71/2; Inkiov (Bulgaria) 7; Miles (GB) 61/2; Barlov (Yugoslavia) 6; Hickl (W. Germany) 5; Barager (Canada) 11/2. Tony Miles's performance was miser- able, one of the worst of his career. Any thought that he might have been spurred on by the other British triumphs at Suboti- Ca and Szirak was rapidly dispelled.

The Canadian organisers of the 1988 Candidates' tournament have told me that the first round pairings will be as follows: Yusupov (USSR) v. Ehlvest (USSR); Kor- chnoi (Switzerland) v. Hjartarson (Ice- land); Short v. Salov (USSR); Timman (Holland) v. Sax (Hungary); Spraggett (Canada v. Sokolov (USSR); and if John Nunn beats Portisch in their play-off he will Play Vaganian (USSR) while Jon Speelman will meet Seirawan (USA). The seven winners from the first round of the Candi- dates' will he joined by the loser of Kasparov-Karpov from Seville to form the eight quarter-finalists. These pairings have yet to be confirmed by Fide", so changes should not be ruled out.

Here is a selection of games from the Zagreb Interzonal:

Korchnoi's opening wasted too much time. (. . 01)6-0 and . . Bxc5-e7). From the diagram position Nogueiras launched a bold offensive to which his great opponent could find no answer.

Griinfeld Korchnoi: Ray Lopez.

A typical Korchnoi game in one of his favourite defences. White cannot, of course, play 18 Qxc5? (which was actually recommended in the Swiss paper Schachwoche) on account of 18 . . Qg4 19 g3 Qh3.

Baragar Ehlvest: Nimzo-Indian Defence. 1 d4 Nf6 2 c4 e6 3 Nc3 Bb4 4 e3 0-0 Bd3 d5 6 Nt3 c5 7 0-0 Nc6 S a3 Bxc3 9 bxe3 Qc7 10 cxd5 exd5 11 Nh4 Ne7 12 g3 Re8 13 13 Ng6 14 MS Bxf5 15 Bxf5 Ne7 16 Bbl Nc8 17 Rat Nd6 18 Reg RacS 19 a4 Qa5 20 Rfel Nc4 21 Qd3 Nb6 22 e4 c4 23 Qe2 dxe4 24 fxe4 Qxa4 25 Qd2 Re6 26 Q14 Qb5 27 Bc2 Qh5 28 Qfl Qa5 29 Q13 Ree8 30 g4 R6e7 31 g5 Nfd7 32 h4 Nf8 33 Rfl Na4 34 Bd2 b5 35 Ref2 Nb2 36 h5 Qb6 37 e5 a5 38 Kh2 b4 39 Be4 Nd3 40 Rg2 h3 41 g6 hxg6 42 hxg6 Nxg6 43 Rxg6 fxg6 44 Bd5+ Re6 45 Qf 7+ Kh7 46 Kg3 Black resigns. Baragar's sole win in the Interzonal. Ehlvest should have steered for a draw with 29 . . 0h5, but probably did not conceive that he could lose.

The Lloyds Bank Masters has been won jointly by Michael Wilder (USA) and Murray Chandler, both scoring 8/10. The trophy goes to Wilder on superior tie- break, but Chandler earns the title of Commonwealth champion for the coming year. Other leading scores were: Benjamin (USA), Rogers (Australian champion), Ernst (Sweden) and Fedorowicz (USA), all 71/2. Igor Ivanov, the Canadian cham- pion, and John Nunn were among those

who came next with 7.
