Ing Cup

This article is about the Go tournament. For other uses, see ING Cup (cricket) and ING Cup (football).

This article is about an international Go tournament and is not to be confused with Chang-ki Cup, an affiliated annual domestic Go tournament in China.

The Ing Cup (Chinese: 应氏杯; pinyin: Yīng Shì Bēi) is an international Go tournament with a cash prize of over US$400,000. It was created by, and is named after, Ing Chang-ki.^[1] The tournament is held once every four years and hence often nicknamed the Go Olympics.

In the 7th Ing Cup, held in 2012/13, Fan Tingyu defeated Park Junghwan and became the youngest Ing Cup winner in history. In the semifinal, Fan defeated Xie He, and Park defeated Lee Chang-ho.

Overview

The Ing Cup is sponsored by Ing Chang-ki Weichi Educational Foundation, Yomiuri Shimbun, the Nihon-Kiin, and Kansai-Kiin, and is held every four years (and thus often nicknamed Go Olympics). The competition has its own special rules. There is no byoyomi; instead, players who run out of time pay a two-point penalty to receive some extra time. The precise amount of time has varied historically; in the 10th cup final in 2024, the time allotment was three and a half hours for each player, with a two-point penalty to receive an extra 35 minutes, and players could receive extra time this way at most three times.^[2][3] The komi is 8 points, but Black wins ties.^[4] The first rounds are single-elimination knockouts, the semifinals are best-of-three, and the finals are best-of-five (except in 2023, when the final was best-of-three).^[5][6]
