Round up
Raymond Keene
Last week I promised news of the English assault on the Mexico Interzonal and the Junior World Championship in Den- mark. There is no lack of results from either event, but it has proved difficult to obtain a selection of games. In Mexico after 10 rounds the surprise leader is Torre (Philip- pines) with 7 points, having taken over from Portisch (61/2) who lost to Yusupov in the tenth round. Equal third with 6 points are Seirawan, Spassky and Yusupov. John Nunn lies half a point behind them. Of course, there can be significant changes in the last three rounds, but evidence is emerg- ing that the present system of qualification from the Interzonal (14 players, with only two going through to the Candidates) per- mits an excessive intrusion of chance fac- tors.
Nigel Short is faring none too well in the Junior World Championship. This is his third crack at the title, and his results have been getting steadily worse, declining from the high point of second place behind Kasparov in 1980. The Soviet youth Sokolov leads with the tremendous score of 8/9, followed by Benjamin (US) and Hansen (Denmark) on 61/2, while Nigel is languishing on 5. He will have to score 4 points from his last 4 games in order to challenge for the medals.
Nigel's lack of success in this junior event is all the more surprising in view of his ex- cellent showing in the Ohra master Swiss tournament in Amsterdam last month, where he tied for 1st prize with Vlastimil Hort, and made a GM norm. Here is a game from that tournament by one of the joint winners.

Hort, happily recovered from the health which prevented his participation 111 Bugojno, will be one of the star attractions at the 1982 Lloyds Bank Masters opening at the Barbican Centre on 25 August and run" ning until 2 September. Naturally, I hope to defend the title I won last year, but with Korchnoi, Miles and Ftacnik also in the lists, this problem may be insuperable. Position after 24 ... Nf6
