000ffj Posted August 28, 2012 Report Share Posted August 28, 2012 2NT开叫后的低花选定改进(参照王建坚科学自然)20-21P的2NT开叫,开叫条件、后续叫法完全采用王建坚《科学自然叫牌法——逻辑与思考》里面的内容。 3C 傀儡斯台曼 3D/3H 转换叫 4D/4H 转换叫 3NT 止叫 3S 6张以上低花单套或者5-4/6-4低花双套牌,满贯兴趣 4C 7+以上,5-5低花,或者6-5/6-6低花 关于2NT开叫后详细请参考王建坚的书。2NT号称低花满贯杀手,能否妥善处理低花满贯是2NT后续成败的的关键。 2NT 3S 3NT 无4张低花或4-4双低花 4C/4D 4张以上套,另一低花至多3张 1. 2NT-3S-3NT后续 2NT 3S 3NT 4C/4D 低花Smolen,所叫低花4张,另一低花5张以上 4H/4S 6张以上C/D的单套牌 (1) 2NT 3S 3NT 4C/4D 4D/4H 加一级,对D/C有3张以上配合,关键张问叫 4H(4C后)/4S/5C(4C后) 扣叫,对5张低花的配合 4NT 示弱,无配合 5D/5C 低限,对D/C的3张配合 (2)2NT 3S 3NT 4H/4S 4S/5C 加一级(除4NT),对C/D套有配合,关键张问叫 4NT 示弱,2张配合 5C/5D 低限,对C/D有3张配合 2. 2NT 3S 4C/4D 4D/4H 加一级,指定C为将牌 4H/4S 加二级,指定D为将牌 之后开叫人加一级的接力叫为关键张问叫 4NT 显示4张配合的温和满贯邀叫 4S/5C 加三级,配合开叫人所叫花色并显示余力 上述叫法看上去非常复杂,其实逻辑很清楚: 1.开叫人的4C 4D是实叫 2.一方显示低花后,如果两个低花都可能成为将牌,加一、二级分别制定C D为将牌 3.如果一个低花可能成为将牌,加一级就是对该花色的关键张问叫;4NT是最弱叫品;5C 5D为配合低限 Quote Link to comment Share on other sites More sharing options...
yzdhy668 Posted August 28, 2012 Report Share Posted August 28, 2012 叫法看上去非常复杂,慢慢学习,谢谢沙漏。 Quote Link to comment Share on other sites More sharing options...
21574770 Posted August 29, 2012 Report Share Posted August 29, 2012 2NT开叫限制性很强,不过手段好像没1NT开叫来得多 Quote Link to comment Share on other sites More sharing options...
shingkit Posted August 29, 2012 Report Share Posted August 29, 2012 非常有用,谢谢沙漏。请问2NT - 4C后的进程有什么值得注意的地方吗? Quote Link to comment Share on other sites More sharing options...
000ffj Posted August 29, 2012 Author Report Share Posted August 29, 2012 我也是借花献佛,自己还没有搞清楚这个约定叫,更无从谈体会呢。 :rolleyes: Quote Link to comment Share on other sites More sharing options...

yunling Posted September 5, 2012 Report Share Posted September 5, 2012 其实2NT开叫之后寻求低花满贯最大的问题是3NT以下无法及时表达单缺所在,这一点是无解的 Quote Link to comment Share on other sites More sharing options...
yzdhy668 Posted September 5, 2012 Report Share Posted September 5, 2012 这个约定叫很好。哈代对2NT开叫后,应叫人持双低花未作详细描述,现存在多版本,不是很熟悉的PD,易出现偏差和混淆。 Quote Link to comment Share on other sites More sharing options...

hejiang Posted September 6, 2012 Report Share Posted September 6, 2012 在开叫2NT后,我所使用的是刘世康桥牌世界标准(BWS),我倾向于使用这一叫法。2NT-3S-3NT(规定再叫)-?,之后4C是D单套,接力问关键张;4D是C套,接力问关键张;4H/4s是双低套,所叫花是单缺,4NT双关键张问叫。 Quote Link to comment Share on other sites More sharing options...

yzdhy668 Posted September 9, 2012 Report Share Posted September 9, 2012 这个约定叫中好象没有4C或4D止叫的叫品。应叫人持低花弱牌NT打不成,4阶低花可一搏,不能是只要应叫人叫牌就进局,如何表示应叫人持低花弱牌可在4C或4D止叫? Quote Link to comment Share on other sites More sharing options...

yueliang Posted March 21, 2013 Report Share Posted March 21, 2013 开叫人持整副牌的一半点力,却无谓地跳空开叫2NT,自己封杀了大量的叫牌空间,实在没什么必要。 Quote Link to comment Share on other sites More sharing options...
