As it turns out, the country's socialist government adopted the chess system of the former Soviet Union, which produced five undefeated world champions between 1948 and 1972.
"Sports clubs are spread throughout the political structure of provinces and cities," says Casto Abundo, deputy president of the Asian Chess Federation. "Each club has its own budget at its disposal and they concentrate on the development of the youth. They are now harvesting the fruit of their labor."
