Go, the ancient board game that China, Japan and South Korea all claim as part of their cultural heritage, is struggling to expand its global footprint because the three nations that dominate it cannot agree on something as basic as a common rulebook. When Go was registered with the International Mind Sports Association alongside chess and bridge, organizers had to adopt the American Go Association's rules because the East Asian trio failed to reach consensus.
