注意:2D解释为 1 maj,意思:一套高花。

问题:
这牌四明手根本打不成3nt的,如何发现高花配合?防守时敢不敢及时换攻HK?!

首先,注意一下开叫1n的点力,麦罗应该是14-16,而另外一边提示了13-16.
麦罗这桌在pd叫过2h的情况下,还继续s多少让人有点费解。
明手d套很可能吃通的,而自己再无直接进手,cQ庄家也只可能选择砸而不会飞到你手中;
同伴有多少p?极限也就5p左右,而庄家选择忍让sA,明显可能还要脱手一次,同伴应该还有次进手的机会,这个时候选择换攻h就迫在眉睫了;
换h有2个选择,一个是希望同伴有hA,直接吃到4墩以上h。还有一个希望同伴有hJ和cA。基于我方叫出h后opp还叫3n,选择同伴有hJ是合理的,所以应该换攻hK;
另外一边没有叫出h,相对困难一点。但如果仔细分析一下,换hK宕的机会还是明显要好过继续s,主要还是明手的d套威胁太大了,庄家基本上已经有了8墩,这个时候需要积极的换攻。
至于叫牌,1n后表示双高的约定叫很多。至于64套的时候该如何选择,这个话题就宽了,就这幅而言,因为是KQJxxx的好套,选择只表示s套很正常。如果用海洛,我也选择2s而不是2h。

6-4 capelletti 2D 是雙高,就此牌而言,如1NT - 2D 後是雙高,一盤低花不超過4張。如PARTNER 有CK 則怎打也不成,整副牌在搶TEMPO。如叫2D,同伴回應2H,則明顯在首攻SK 後立刻換HK 打死明手的單張Q。

在两室里都是同样的首功和同样的垫牌,都是垫10,可就是双方都是痴心不改,执拗地继续进攻,令人费解。

从心理上说,让人家打上二阶定约,心理上总是难舍不肯的,不愿意防守的另一个原因就是因为非均型有花色长度缘故。
而pass是过于持重的表现。

North 最後的PASS 有問題。為何不補上一刀?

要是PARTNER 在S 上沒防守能力,叫回3H 也可以。

这个黑桃10我觉得不是要换攻红桃的意思,北家那样的红心,期望同伴有K10XX?

我作为北,不会pass。可能会叫3,叫3NT也有可能。

这副牌南北有4,但很难叫上去。

N家在对方的1NT后就不该PS,况且同伴还加倍了

你愿意开叫1还是1
当时在场解说员法国黄星星ritong说:我不知道为何不开叫1.
我倾向于开叫1.
的确这里有派别分歧,4-4低花时,如果均型,我愿意开叫1,非均型,那就开叫1.不知道大家以为如何?

开叫低花后,准备第二口应该是叫2N,所以仅这副牌来说倒没有什么大的分别。

開1D,因為再叫不是2C而是2NT。

此牌不符合逆叫條件。逆叫的第一套總是5張。如5422 的牌型。

两种流派都可以举出因为开叫这门低花而错失另一门低花配合的例子。

1C --1H
2NT--3C
3D --?(应叫人4张D停在3D不心虚吗?)

1-是心虚,没错。不过这时应叫人多半选择pass同伴的2nt
2-不论如何开叫,应叫人都应该pass的。

开叫1D。D套比C套多个Q,再叫就2NT。
哈代2/1体系,低花3-3就开C,4-4就开D。
