Ko ‘Has’ Yu-Feng is a Taiwanese Protoss player who began his career as a pro Starcraft II player in April 2013.
Has is currently most famous for an upset against Jaedong in the losers’ match in Group D of the 2014 WCS America Season 1 Premier League - and particularly for the decisive Game 3 on Polar Night, which he won with the help of a cannon rush on Jaedong’s natural expansion using only Pylons in the initial wall. The strategy was successful, and the game became one of the most noteworthy in the first group stage of the tournament.
On 22 February 2015, Has competed in Group F of 2015 WCS Season 1 Premier League. Initially he lost to NaNiwa, but he then defeated Suppy and won over NaNiwa in the rematch to advance to the round of 16. In the Round of 16 group stage Has lost 1-2 to Kane, and won 2-1 against Welmu in his first two matches. Facing Bunny in the deciding match, Has was defeated 0-2, and was eliminated from WCS Premier Season 1, finishing at 9th to 12th place. The early-aggression style showcased by Has in this round of 16 allowed for games being played differently from the usual, which was met positively by users of the StarCraft subreddit, and also caused laughs from Kaelaris while he was casting one of Has’s games.
His challenging spirit has not only won popularity locally, but has become a topic of discussion in international settings.
