MLily Cup

MLily Cup

The MLily Cup is an international Go (game) tournament sponsored by a mattress manufacturer and contested by elite professionals from China, Japan, South Korea, Taiwan, Europe, and other regions. It attracted top-ranked players from associations such as the Chinese Weiqi Association, Korean Baduk Association, and Japan Go Association and became notable for its large purse, rapid schedule, and influence on modern professional opening theory. The competition spanned several editions in the 2010s and early 2020s and featured many of the era’s leading titleholders and international stars.

Overview

The MLily Cup was structured as an international invitational open to professionals endorsed by national organizations including the Chinese Weiqi Association, Korean Baduk Association, Japan Go Association, and regional bodies like the Taiwanese Go Association and European Go Federation. Champions and top finishers from major domestic titles such as the Chinese Weiqi Championship, Korean Baduk Championship, Japanese Kisei, Tengen (Go), Honinbo, Meijin (Go), LG Cup, Samsung Cup, and Ing Cup often participated. Prominent names in its fields—winners and contenders such as Ke Jie, Lee Sedol, Gu Li, Park Junghwan, Iyama Yuta, Cho Chikun, Xie He, Shi Yue, Chen Yaoye, Yuta Iyama—frequently appeared in draws, contributing to strong international rivalry. The cup’s timing, prize money, and pairing format made it a focal point alongside other global events like the Fujitsu Cup and BC Card Cup.

History and format

The inaugural edition launched in 2012 with corporate sponsorship and international broadcasting agreements that expanded the profile of professional Go (game). Organizers collaborated with the Chinese Weiqi Association, Korean Baduk Association, and Japan Go Association to invite seeded participants and qualifiers from national championships such as the China Weiqi Championship, Korean Baduk Championship, Japanese Kisei, and regional qualifiers run by organizations like the European Go Federation and the American Go Association. The tournament employed a single-elimination bracket with extended thinking time and a komi established by professional consensus; semifinals and finals used multi-game series, mirroring formats used in the Samsung Cup and LG Cup. The event occasionally adjusted rules and time controls in response to debates involving the Japan Go Association and rule differences between Chinese and Japanese professional circuits; these discussions echoed earlier inter-association negotiations seen during Ing Cup arrangements.

Qualification and participants

Participants came via nomination and qualification, including national titleholders from events such as the Chinese Weiqi Championship, Korean Baduk Championship, Nongshim Cup team selections, and domestic leagues like the Chinese Weiqi League. Invitations also targeted top-ranked professionals in global rating lists such as those maintained by the International Go Federation, and regional federations like the European Go Federation and the American Go Association could send representatives following qualifying tournaments. High-profile invitees included multiple-time international champions from the Samsung Cup, LG Cup, Ing Cup, and Fujitsu Cup circuits—players such as Lee Sedol, Ke Jie, Gu Li, Park Junghwan, Iyama Yuta, Cho U, Shin Jinseo, Ding Hao—ensuring depth and cross-generational matchups. Wildcards occasionally allowed rising stars from amateur competitions like the World Amateur Go Championship to compete alongside established professionals.

Tournament results

Across editions, winners included leading figures from China and South Korea who had previously secured titles in major tournaments such as the Samsung Cup and LG Cup. Finals frequently pitted representatives of the Chinese Weiqi Association against those from the Korean Baduk Association, echoing rivalries seen in the Nongshim Cup and LG Cup finals. Notable champions and runners-up included players whose resumes featured victories in the Ing Cup, Fujitsu Cup, and domestic grandslam events like the Honorary Tengen and Lifetime Meijin equivalencies. The prize structure mirrored other premier events, offering winners substantial purses that affected professional rankings maintained by bodies like the International Go Federation and national rating lists.

Notable games and legacy

The MLily Cup produced several high-profile games that influenced contemporary opening trends and fuseki exploration, with significant encounters involving players such as Ke Jie, Lee Sedol, Park Junghwan, Gu Li, Iyama Yuta, and Shin Jinseo. Games from the cup were studied in professional commentary programs and by authors who recorded variations in collections similar to analyses of matches from the Ing Cup and Samsung Cup. The tournament’s role in stimulating rivalry among the Chinese Weiqi Association, Korean Baduk Association, and Japan Go Association contributed to pedagogical materials used by academies like those led by Lee Changho protégés and training schools in China and Korea. As corporate sponsorship landscapes shifted, the cup’s legacy persisted through recorded game databases, professional game collections, and its influence on scheduling and prize standards adopted by tournaments such as the Samsung Cup and LG Cup. Its games continue to be referenced in studies by authors and institutions chronicling the modern evolution of professional Go (game) strategy.
