World Championship
World champion Mikhail Botvinnik and challenger Tigran Petrosian start their grueling 24-game match today at Moscow. The schedule calls for three games per week. In case of a tie the champion retains the title. Their styles are similar, with caution the key-note, and protracted struggles can be anticipated.
The FIDE world team championship at Varna, Bulgaria, last fall is the only serious competition that the champion has engaged in during the year. He should have lost to Bobby Fischer and was soundly outplayed by Uhlmann in the following. Now 51 he will need all his resources to overcome the 33-year old challenger.
