2NT OR PASS。
如果要叫的话,我愿意叫出2NT;
如果考虑失配(同伴的D你单张,而对方的S你有四张)的可能,联系局况,也可能选择PASS,毕竟是低限的牌。

这牌opp有一套配合,我们很可能有套的配合,同伴的低花可能有9张以上。叫2NT或许是最好的选择。
正确的判断来自经验,而经验常常来自错误的判断。

寻找自己的错误才是学习桥牌的唯一进步方法

低限,花色配合不好,不pass想干嘛?
2nt?万一同伴认为2nt不好打,觉得6-1配是个好打定约?
pass目的是要仔细聆听同伴的心声,你没有描述性的安全叫品了。

当然PASS,同伴有逼局实力他自然会再叫。

PASS,不是每副牌都要争部分定约。

二盖一应叫以后,直接位置的加倍是惩罚性的,方块不配合,好的4张黑桃,你可以加倍。当然同伴不是一定要放过,比如他拿着- Qxx KQ98xx Kxxx,应该叫3C;拿着- Qxx KQJxxxx qxx,应该叫3D;拿着- Axx AJ98xx Kxxx,应该扣叫3S。
你加倍,传达的信息就是,D不配合,S不错的四张套。

按照劳伦斯的理论就是X表示惩罚,由于同伴向你表示了二盖一的实力,加之南北方又失配,防守是有前景的。北至少有10个牌点,但他也可能有更多牌点。加倍是建议而不是命令。

嗯,如果pass为的是逼叫,那么加倍就是为了惩罚。这是一个有用的思路。
