madongjun Posted October 20, 2013 Report Share Posted October 20, 2013 [hv=pc=n&s=s7hk532dtcajt7643&n=saha764daq98ckq95&d=n&v=e&b=9&a=1dp2c3s4sp5cp6cppp]266|200[/hv] 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？ Quote Link to comment Share on other sites More sharing options...
nbxkh Posted October 20, 2013 Report Share Posted October 20, 2013 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。 Quote Link to comment Share on other sites More sharing options...
bgm Posted October 20, 2013 Report Share Posted October 20, 2013 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. Quote Link to comment Share on other sites More sharing options...

madongjun Posted October 21, 2013 Author Report Share Posted October 21, 2013 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。 Quote Link to comment Share on other sites More sharing options...
