Just four teams came to Warsaw to contend for the challenge cup awarded to the winners of this Warsaw Pact Armies event. The Soviet Union fielded four titled plarers and an obscure 18-year old one named Anatoly Karpov as a reserve. Czechoslovakia, the titleholders were missing Jansa and Janata, last year's team leaders.

In the beginning Poland surprisingly beat Czechoslovakia in what many believed was a direct duel with second position at the stake. On the second day the Soviet Union wiped out poor Czechoslovak team with a clear 4-0 while Poland dropped just a fraction vs Cuba and with one day to go they had a clear 4½ advantage over the Czechs thus their position being unendangered. On the last day they needed a 3-1 win vs USSR to win the title but they were light years away from it and lost 0-4. Czechoslovakia beat valiant Cuba and finished third.

The Soviets won 11 games and drew one (!). Filipowicz of Poland was the only player of his team to achieve a plus score. The Cubans were weak, but not Hernández, their leader who scored 2/3 at top board without a loss. Not very surprisingly, he became a well-known GM soon.
