这是昨天晚上的牌,看似简单,其实暗藏重重机关,西家首攻dt,南家Jec连第一关都没通过(da后直接出红心,希望东家放小。)
第一关黑桃垫方块势在必行。
第二关接着打红心断对手桥同时联通自己桥也是自然,后边我先初看边花四墩,将牌只要7墩,好像唾手可得,真的吗?
第三关东家红心上手回出草花是好手,仔细一瞧自身桥梁还有问题,庄家有两个路线
1、暗手c6明手c9正常,可是当从明手打方块的时候,东家跟出小方块杀手锏西家将吃,然后回出将牌,由于明手只有一个进张了,即使树立了方块也无法兑现,由于清了2轮将,也无法赢得7个草花,定约必下。
2、暗手赢得第一个草花再打出dq,可是这时候东家dk大了接着方块,将来西家的c7必然看住庄家的c6,依然无法得到7个草花。
我是庄家的话,遇到这样的对手我只能投降致敬了,您还有高招吗?

No this deal 5 by S must down 1 under perfect defense. And 5 will also suffer from ruff.

And the only cold game in this deal is 5 by N, which only possible if NS play some transfer scheme.

谢谢。但是无论南家还是北家5c在草花首攻下好像都是无法完成的。

You have 5, 3, 2 (wtih K knocked out at last), and 1 ruff for 11 tricks.

For 5 by N, if E lead his trump, declarer can concede a , and at best W can win and draw another trump.
But S can still win and ruff a , cross back with Q to draw the remaining trump, discard the last on ,
and finally knocking out K for 11 tricks with still a trump on hand.

我坚决不认为这是合理的好的叫牌序列,不管北家是谁,就算是响当当的世界级牌手,也未必总是精神饱满,副副得宜。
好的叫牌应该是同伴更容易完成定约,坏的叫牌也很容易陷于不必要的苦战而耗费大量的体力。这点在大型比赛期间尤为重要。
如果是我,在1后,第四家的我就叫2,这牌5定约不难得到,而且非常轻松完成。而定约5,这个穷兵黩武的定约,四处漏风,顾此失彼--就是说,能否完成定约,运气分布占有一多半的比例,运气好的时候还可以打,运气一般的时候,就要寄托对手能否出现大漏勺,这是这类牌的本质。
机关重重,更多地来自己方的自我缠缚,非对手也。
大家看看,庄位问题,富含防守张的强牌一方成为明手,导致对手更容易计算防守,如果倒过来,情况就会出现不同。这都是北家未能及时叫出6张长套惹的祸。于是乎机关重重了,自讨苦吃。戒之戒之。

即便如此,我还是认为这是一个好帖子,一个富于思想,富于技术特色值得阅读欣赏的好文贴。
