2/1体系,同伴北家是开叫方,开叫PASS,RHO开叫2♠.
持上述牌,你如何继续?

激进者直接3nt是有的,稳妥者2nt,不逼叫。

实战的四个进程:
1、

结果:3NS-3,-300,33.33%(南北方)
2、

结果:3NXW-2,300,100%(南北方)
3、

结果:2SE=,-110,66.67%(南北方)
4、

结果:4NXS-4,-1100,0%(南北方)

四个进程中,从南北方向得分来看:在2♠后争叫2NT的第1进程和第4进程,分别位于3/4和4/4;在2♠后PASS的第3进程,位于2/4;东家未阻击开叫2♠的第2个进程,位于1/4。

根据上面的实战叫牌过程,看来队员对这个2NT是否逼叫还不太清晰。
四手牌如下:

哎呦,楼主总结得太好了,非常有意义,这样四桌比较结果比TM更有教育意义。

其实2nt后就该pass;如果再遭遇惩罚性加倍也可以考虑自行逃叫至3♣,不就息事宁人了嘛Posted Image

我的是进程一,得到33.33%的比赛分。
问题是:持4135的非均型牌,能不能在对方2♠后叫2NT?(象进程3一样PASS?加倍不能考虑,因为没有另一门高花。)
