这是昨晚来自CBC训练赛上的一副牌例

东西家体系:precision
结果:3N-2

另一桌结果:3N-1



问题是:请大家评论一下第一和第二桌,各自犯了什么错误?

这是一副让我感动震惊,感到深深不理解的牌例。错误方都是老麻将了,这样的牌手之所以犯这类错误,主要原因是平素根本不注重读牌力的培养训练!

第一桌,尽管精确是11点开叫,但有两个q,都没有受保护,减值。第一第二位置不该开叫。
第二桌,应该邀叫2nt。更何况同伴第三家轻开叫的可能。

这副牌闭室叫到3nt,都是首攻10.
做庄路线都是第一墩吃住第二墩都是出Q,开室北家A吃住后,换攻K这是防守杀着!当J再次上手后,北家再出,到此南家已经树立起一墩是进手,最后兑现J,开室2NT Mk.闭室的防守与开室不同,第二墩北家A吃住后,换攻J,此举值得商榷。的换攻,等于提前将南家的进手用掉,导致最后无法兑现J。同时帮敌人树起一墩,完成3NT定约。
