结果:3NW+1
讨论:
1-北家最好的策略是直接加叫3而不是2,虽然无大过。
2-东家在2后直接3是不适切的。(东西家打精确体系)
那么,就我们二盖一体系而言,在2如何表达邀请和止叫序列呢?


附:这是另一桌叫牌

1、2可以接受,牌面的攻防比值太低
2、东家3=竞争实力,甚至是承若牺牲?

另一桌,我还是会先加倍再说

感觉东家在2S后pass是正常应对,3H有点过了了,至少也得有个8点吧?

如果CK给北(其它大牌作一些调整),C飞失之后,看到明手这样的H,转攻H就不是困难的事。

那么3NT就会-1,是不是就变成西叫得不好了呢?

这种边缘上的局,不能以成败论英雄。就像我另一条线上说的,成是运气,败也是运气。

这幅东家积极的争叫2d获得成功。顺便说一下昨天晚上对俄罗斯的一幅牌:

记得田野认为这个2d有点过,我认为在可叫范围类。 首先,必须是自己无局,无对有当然是最理想。其次,pd pass过,通常他不会叫的过高,而opp的第一家也pass过,在这个时候,2d相对安全。
当然,也有付出代价的时候,但2d这类积极的争叫,个人认为还是可取的。

这幅属于边缘局,基于无局和对2d的不确定性(首次pd,不知道是否用这样的drury),没有叫上4s。
实战w家虽然是专家级牌手,但将吃第3墩d也稍显随手,给了庄家一个剥光投入残局的机会。
这里我认为,在已知将牌分布,(东的s9通常判断为单张)的情形下,而自己有3张将牌的时候,在将吃前应该考虑一下庄家为什么先不掉完将这个问题?
其实稍微思考一下,就会发现放弃将吃d可能会更好;
另外一桌的定约和首攻完全相同,庄处理的稍显粗糙,没考虑到S22时有投入的机会。
