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。
