그런데 세미 파이널에서 또.

패자조 선수가 이길려면 3전 2선승 두번 해야한다든지 그런거 있나요/

승자조는 한번도 진적 없으니..

If a Semifinal is a rematch of Championship Winners Bracket Round 1, then it will be a BO7 starting from the score of the first series (extended series rule).

If a Semifinal is not a rematch, then it will start as a BO3. If the player coming from the Losers Bracket wins the initial BO3, then the series will extend to a BO7 starting from the score of the first series. The winner of the extended BO7 advances to the Final Match. (The player coming from the Winners Bracket only needs to win the initial BO3 or the extended BO7 to advance.)

패자조에서 온 선수는 3전제로 시작하고 7전제로 바뀌는것 같네요
