lycier Posted April 27, 2013 Report Share Posted April 27, 2013 (edited) Playing XYZ, what should 2D mean (by a passed hand) in the auction P-1m-1H-1S-2D (2C would still be XYZ even by a passed hand)? Thank you. 这是一道来自BBO专家级桥牌论坛的问贴,我替提问者总结大意是:在使用XYZ约定时,由pass过的应叫人再叫2♦是什么意思?(再叫2♣仍旧是XYZ序列) [hv=d=n&v=0&b=1&a=pp1cp1hp1sp2d(%3F)p]133|100[/hv] [hv=d=n&v=0&b=1&a=pp1dp1hp1sp2d(%3F)p]133|100[/hv] 谢谢。 Edited April 27, 2013 by lycier Quote Link to comment Share on other sites More sharing options...
lycier Posted April 27, 2013 Author Report Share Posted April 27, 2013 由于我已经在专家论坛作答案,请朋友们先独立思考,独立作答,暂时不要去观看我的最后解答方案。 Quote Link to comment Share on other sites More sharing options...
AKQJ2008 Posted April 27, 2013 Report Share Posted April 27, 2013 第一例 应该是暗示h可能5张的过渡叫牌 有邀请的意思吧?第二例 就应该是对D的邀请 Quote Link to comment Share on other sites More sharing options...
madongjun Posted April 27, 2013 Report Share Posted April 27, 2013 第一例,不叫过的好牌,寻求3NT。第二例,支持方块,不叫过的中限牌力,让同伴决定定约的高度。 Quote Link to comment Share on other sites More sharing options...

xhq Posted April 27, 2013 Report Share Posted April 27, 2013 22日我发了一副牌,这副牌在比赛中制造出大的输赢,请大家看看当时的叫牌进程:[hv=pc=n&s=s52h54d754c876542&w=sqjt876hd863ckq93&n=sahakqjdakqjt92ca&e=sk943ht987632dcjt&d=w&v=0&b=8&a=2s3s4spp5sp6cp6sp7dp7sp7ndrppp]399|300[/hv]。这手牌明手摊牌后直接声称7NTmk,而闭室西家也是首开2♠,北家直接争叫7NT结束了叫牌。这副牌开室的北家知道直接叫7NT是一副平牌。他采用了诱敌深入的计谋使敌人上当,给对方造成他们叫牌出了问题的假象,引诱敌人加倍他顺势再加倍。这副牌赢了760分,13IMP。大家如有兴趣请看龚启英著的《醉牌》——桥牌出奇制胜36计。 Quote Link to comment Share on other sites More sharing options...
xhq Posted April 27, 2013 Report Share Posted April 27, 2013 许多人都熟悉一个防家持双张大牌的终局打法,意图迫使敌方给你一吃一垫。这是庄家缺少一墩并且有一个不可避免的输张时经常使用的方法。如果某花色的分布类似这样: ————————10853 ———— Q942 —————— KJ ——— —————A76庄家可以简单敌兑现A,再用小♠脱手。但是如果这门花色的分布是: ——— —————10853 ———— QJ94—————— K2 ————————A76 东家在A上跟K,即可避免被投入。 —————————10853 —————KJ92—————— Q4 —————————A76在这样的分布下,如果东家赢进第二轮就被投入了,但西家可以上K来解救同伴——这叫“鳄鱼妙招” (Crocodile Coup)。 Quote Link to comment Share on other sites More sharing options...
601821297 Posted April 28, 2013 Report Share Posted April 28, 2013 我的想法如下,请指正:第一幅:非均型,10-11P(通常11P)第二副:非均型,有4张D支持,没有4张S,C没有止张,弱示选回搭档的第一开叫花色 :P Quote Link to comment Share on other sites More sharing options...
madongjun Posted April 28, 2013 Report Share Posted April 28, 2013 我说咋这么熟悉,果然是醉牌中的那副牌。我曾把这副牌发在了BBO“有趣的一手牌”论坛,标题叫“大满贯扣叫”(原文的标题)。 Quote Link to comment Share on other sites More sharing options...
lycier Posted April 28, 2013 Author Report Share Posted April 28, 2013 2♦=5♠+4♦,not forcing .Actually, it let pd select 2♦ or 2♠ in the most of the auctions,a sign off sequence. 2♦=5♠+4♦,不逼叫。其实在大绝多数上述进程中,是让同伴选择 2♦ or 2♠ 为将牌的止叫序列。 Quote Link to comment Share on other sites More sharing options...
haikuo Posted May 8, 2013 Report Share Posted May 8, 2013 庄家是能打出,但对防家防守压力较大,哈哈! Quote Link to comment Share on other sites More sharing options...
haikuo Posted May 8, 2013 Report Share Posted May 8, 2013 哈哈,不管如何叫,自己没个赢墩如何去叫加倍? Quote Link to comment Share on other sites More sharing options...
haikuo Posted May 8, 2013 Report Share Posted May 8, 2013 2D不逼叫是一定的,所以就是示选! Quote Link to comment Share on other sites More sharing options...
dvd Posted May 8, 2013 Report Share Posted May 8, 2013 2d我认为应是等待叫,至少逼叫一轮,让pd进一步描述自己的牌情。也就是手里的牌在pd叫了2轮后,估值已发生变化,足以发动成局试探的牌。通常应该是未开叫的高限,而且已找到将牌配合。 Quote Link to comment Share on other sites More sharing options...
lycier Posted May 8, 2013 Author Report Share Posted May 8, 2013 我主张:下一就是好牌。所以有些时候,加倍似可不必。我记得美国著名的stayman大师也有过这类杰作。 Quote Link to comment Share on other sites More sharing options...
xhq Posted May 10, 2013 Report Share Posted May 10, 2013 假如你试图树立一门花色(通常5-3配合),并且可以承受输两墩。如果不会造成进张问题。可以考虑从三张带一大牌的那边出大牌。比如下面这种局面:北家持♠KJ742;南家持♠Q65。如果西家持♠AT9X,引Q将使他非常尴尬。如果他忍让你已经成功完成中国式飞牌,接下来可以提升明手的大牌。中国式大牌提升也可用于你需要在一个4-3配合的花色发展出两墩,同时不让 敌方树立起第二墩的情况,比如:北家持♠QJ83.南家持♠K72。南家从手中引K建立两个快速赢墩。如果西家持AT9X,先引小牌到Q,在为自己树立两墩的同时不可避免地也要给敌方树立起第二墩。先引K如果西家忍让,你已经对他实施了中国式飞牌。 Quote Link to comment Share on other sites More sharing options...
