Hello! ↵
↵
[XXII Open Cup. Grand Prix of Daejeon](https://official.contest.yandex.ru/opencupXXII/contest/35265/enter) <s>will be held in [2022/02/27 Sunday, 17:00 KST (UTC+9)](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20220227T05&ah=5). </s> is **postponed indefinitely** due to the Russian invasion of Ukraine.↵
↵
Daejeon is home to [KAIST](https://en.wikipedia.org/wiki/KAIST), but the contest itself has little to do with it, it just inherits the spirit of 2019 Daejeon GP.↵
↵
The contest was used as a Day 2 Contest for Petrozavodsk Winter Camp 2022. I'm sorry for the camp participants over the lack of editorial. I will work to publish the full editorials right after the GP.↵
