The Ing Cup was the second world go championship, starting in August 1988, a few months after the 1st Fujitsu Cup. It has been held regularly every 4 years (notice how the schedule matches that of the Olympics). The event was conceived of by Ing Chang-ki, and is partly sponsored by the Ing Chang-ki Weichi Educational Foundation. The winner's prize is $400,000.
The 1st Ing Cup was a 16-player knockout tournament. This was increased to a 24-player knockout for the 2nd Ing Cup, with 8 players being seeded into the second round. The semifinals are best of three matches, and the final is best of five. Games are played according to the Ing rules, including an eight point komi.
So far the event has been won by a different player every time.
