That's 3 players in the top 10. Could be a wee ego battle as to who plays on what board.
And will any of them settle for board 3?
Also the appearance fees for all three to play will be very expensive.
The Russians had no problems fielding very strong teams, the players were told
they would be playing . Often their teams read like a 'Who's Who' of past, present
and future World Champions, their 1960 line up was:
Tal, Botvinnik, Smyslov, Petrosian, Korchnoi and Keres.
A current World Champion (Tal) , Two Ex World Champions (Botvinnik and Smylov
though of course a few months later Botvinnik would win his title back),
One player destined to become World Champion in three years (Petrosian) .
One player who played two (in effect three) World Championship matches (Korchnoi)
One player often quoted as the strongest player never to become World Champion. (Keres.)
