你是南家,你的同伴开叫1D,你应叫了2C,你和你的同伴顺利的叫到了6C,在叫牌时,西家曾争叫过黑桃。
西首攻是红心J,东家在明手的A下跟Q,你调将到明手,将牌是1-1分布,你想:如果红心3-2分布,你就没有任何问题,你兑现红心K,西垫了张黑桃,你如何安全的完成定约?

单有局,西家阻击到3s,肯定是7+黑桃好套,而未首攻,红桃必然单张,余下的红桃中间张都在东手。办法1、完成定约,必然寄托于方块。拨方块a后,明手继续方块,将飞。只要dkj不集中在西家,定约可成。办法二,打东家有dk的情形,送出一敦红桃后,利用红桃套和方块aq紧逼。概率显然前者大。

-------定约是铁的,西家有dkj也一样。西家吃进有,只能回出方块,给一个自由将飞。若出黑桃,则被一吃一垫。

When the black suits are eliminated, W has no choice but to return for you. So the double ruffing finesse in is a 100% play - either onside, or W is end-played.

是的,在发现红心4-1分布后,你只要取掉黑桃A,先消去黑花色。
注意到方块的号码,外面只有K和J两张大牌,而你有AQT98五张之多,所以拨方块A,方块Q,东若盖就将吃(你随后还能将牌到明手再将飞做大9、8中的一个),东不盖的话就放给西(你垫红心),他要么打回黑桃给你一吃一垫,要么打回方块,把你的9或8做大,你有将牌进入明手,垫去你的第四个红心。(西已没有红心和草花可回了)。

简单吧?但实战中你能正确的发现这条路线,而没有动过从庄家向明手飞西的方块K,用方块垫一张红心的念头吗。
