Estonia condemned hosts South Korea to a 4-3 defeat at the International Ice Hockey Federation (IIHF) Men’s Under-18 World Championships Division II Group A tournament - which is serving as a test event for the Pyeongchang 2018 Winter Olympic Games.

Kim Jaeyoung gave the hosts the lead at the Gangneung Hockey Center but Kristofer Jogi and Artemi Aleksandrov turned the match in Estonia's favour.

Kim Minje drew the Koreans level again but Aleksandrov bagged his second of the game a little over five minutes from time.

With under a minute left, Park Gangeun equalised again to send the contest to overtime.
