The most surprising development in the new World Chess Federation ranking list is the relegation of Victor Korchnoi to third place, on 2645, behind Karpov 2720 and Timman 2655. This drop of fifty points Lects the ex-challenger's poor score at as Palmas and his demolition by Karpov at Merano, while Timman has been suitably rewarded for his Las Palmas and IBM wins.

other leading players (difference from ve previous list given in brackets) are: Parov 2640 ( + 10); Portisch 2630 26,12a): Spassky 2625 ( — 5) and Hilbner

( — 20).

For the first time there are six English' home ratings of interest are: Chandler 2470, Paul Littlewood, British champion, 2460,

Hartston 2450, Taulbut 2435, Short 2430, Pritchett (top Scot) 2410 and Botterill (top Welshman) 2400. The best ladies' ratings are: Chiburdanidze 2390, Alexandria 2380 and Kushnir 2330, with Jana Miles at 2240 and Sheila Jackson 2180 as our most promi- nent representatives.

This week I give a striking win by Nunn from the tournament currently in progress at Wijk aan Zee.

players at 2500 or more, namely: Nunn 2590, Miles 2575, Speelman 2550, Stean and myself 2505 and Mestel 2500. This represents not only a general upsurge, but also confirmation of John Nunn's posi- tionn as current English number one and Jon Speelman's as number three. Other

A remarkable demolition of the ex-world champion by Nunn, who has also disposed of Timman and Hort.

Murray Chandler has also distinguished himself by beating Tal, with the Caro- Kann, but in a later round disaster befell him against Hort, from the same opening.
