Long Awaited Piatagorsky Championship
The long awaited Piatagorsky championship will be held this month and looms as a major world tournament.
Fischer and Reshevsky early accepted invitations but, disappointingly, Spassky and Petrosian turned them down. Portisch and Unzicker were substituted. Belatedly Spassky and Petrosian have now accepted and the field will be expanded to 10 players.
The world will now see another major encounter between Bobby Fischer and the Russians, all of which provides a background of great excitement for what is surely a glittering tournament.
