hejiang Posted April 6, 2013 Report Share Posted April 6, 2013 直接3NT了。 Quote Link to comment Share on other sites More sharing options...
dongfz Posted April 7, 2013 Report Share Posted April 7, 2013 对无将定约而言,这手牌中间张不够好,属于较差的12P,在同伴持低限开叫牌力时是否进局确实是比较纠结。我倾向于再应2C(MTWS),同伴2D后再2NT邀请,由同伴决定是否3NT. Quote Link to comment Share on other sites More sharing options...
hongliu Posted April 7, 2013 Report Share Posted April 7, 2013 对无将定约而言,这手牌中间张不够好,属于较差的12P,在同伴持低限开叫牌力时是否进局确实是比较纠结。我倾向于再应2C(MTWS),同伴2D后再2NT邀请,由同伴决定是否3NT. 确实比较纠结,但由于是4控制,牌力还是升值的,所以,我愿意打3NT! Quote Link to comment Share on other sites More sharing options...
000ffj Posted April 7, 2013 Report Share Posted April 7, 2013 打xyz约定叫,我遇到唯一的难点就是这种牌面,应叫人立马要决定是2c还是2d,这种猜断往往很难保证正确,我的想法是结合局况,如果有局,可以2d(只要1/3的机会就可以上),如果自己无局(需要45%左右的机会),稍微保守一点。 Quote Link to comment Share on other sites More sharing options...
madongjun Posted April 7, 2013 Report Share Posted April 7, 2013 确实比较难以决定,担心同伴低限,又担心同伴高限,看来经过一个邀请序列是正确的。毕竟还有两个9,呵呵。 Quote Link to comment Share on other sites More sharing options...
bluejacket Posted April 7, 2013 Report Share Posted April 7, 2013 质量不错的12HCP,立足进局,约定XYZ立刻2D检查同伴牌型分布,3NT最担心是梅花2-2。 Quote Link to comment Share on other sites More sharing options...
00master Posted April 7, 2013 Report Share Posted April 7, 2013 我会2NT直接邀请,同伴不是绝对低限必然接受邀请。先用2♣转移之后再邀请,要求有4张♣的。还有opp可能会用加倍来指示首攻,得不偿失。 Quote Link to comment Share on other sites More sharing options...

wuhuan Posted April 9, 2013 Report Share Posted April 9, 2013 读完所有的讨论我还是很纠结,哈曼法则这里就不灵了?再细想如何你期待打3NT,哪你的期望值是什么——同伴最好持SA、HA、DAK,可这时同伴是不会再叫1NT的。感谢各位老师的出题解答。 Quote Link to comment Share on other sites More sharing options...

zyp163 Posted April 10, 2013 Report Share Posted April 10, 2013 类似的牌例,我至少碰到过N副,因为概率上的原因吧。 当屡次的3N被打宕时,真的应该思考。 因为:完全的均型牌(4333,4432)。且无套(赢墩),无配合(44)。这时,3NT需要26HCP。 HCP在合适的位置是金玉。在不合适的位置是败絮。 我的理解对不? Quote Link to comment Share on other sites More sharing options...
