As indicated previously in Jun 2009, the current 7 + 3 八人淘汰 system has a critical round, i.e. Round 8, to decide all promotion cases and the recent withdrawal of 卷心菜 has generated a number of concerns.
To improve the system further, there are few alternatives : --
(1) 八人双败淘汰 -- 7 + 3 method
for this method, the player with 双败 in the last three rounds not to be promoted, in this case, if someone win with a walkover in Round 8 but having 双败 in Rounds 9 and 10 will not be promoted.
after first round
胜者组 4人 select positions 1, 2, 3 and 5
负者组 4人 select positions 4, 6, 7 and 8
Position and results
1 胜 胜 胜 胜者组
2 胜 胜 负 胜者� (more...)
呵呵，是啊，八强三轮简易双败淘汰制需要八强棋手胜2场才能晋级。
今年6月，针对象总首次采用的8强3轮淘汰制的改进（优于7轮4强直接晋级），我在此基础上设计了一个强三轮简易双败淘汰制，可以继续讨论和改进。也可以在其他一些比赛中先试验试验，找出优缺点。
这种赛制的好处是八强棋手胜2场才能晋级，也不会败一场就淘汰，即使有一人有急事walkover也不会直接造成对手晋级。
