lycier Posted February 2, 2013 Report Share Posted February 2, 2013 [hv=pc=n&s=sakqjt7ht8d87ck97&w=s9hj975daqt6cq542&n=s864hak2dkj432cj6&e=s532hq643d95cat83&d=n&v=b&b=13&a=1dp1sp1np]399|300[/hv] 这是一道基础叫牌练习题。在应用MTWS时，目前大家基础约定知识都已经掌握得不错了。当你持南家牌面，你现在该如何选择：2♦先逼局？3♠表示♠六张的满贯兴趣？还是别的着想？为什么？ 注意：不要企图看四家的持牌图而去索骥。 Quote Link to comment Share on other sites More sharing options...
wuhuan Posted February 2, 2013 Report Share Posted February 2, 2013 要是我就用3S。 Quote Link to comment Share on other sites More sharing options...
lipeng2076 Posted February 2, 2013 Report Share Posted February 2, 2013 我选择4s。手持边花控制弱的半均型，在同伴的1nt后，不报太大期望，简单封局。 Quote Link to comment Share on other sites More sharing options...
sungh Posted February 2, 2013 Report Share Posted February 2, 2013 先2D逼局后再叫3S表示一手垃圾牌面，显然这手牌持一手纯净的S套不能叫2D。3S显示有满贯兴趣，持一手纯净的S套，然而同伴持低限均牌时，你的边花对同伴的帮助不够。不可能想满贯的。这手牌还是直接4S止叫吧。 Quote Link to comment Share on other sites More sharing options...
bgm Posted February 2, 2013 Report Share Posted February 2, 2013 最怕同伴持 ♣AQ♦QJ♥QJ 要選擇3NT Quote Link to comment Share on other sites More sharing options...
lycier Posted February 3, 2013 Author Report Share Posted February 3, 2013 最怕同伴持 ♣AQ♦QJ♥QJ 要選擇3NT 还是香港大师说得对，说的简单明了。分析一下： 1-叫2♦逼局？目的何为？尽力寻求♠配合？必须尽量选择4♠为最佳进局方式？2-叫3♠满贯兴趣？你没牌型，又控制很少，开叫方再叫1nt是限制性的，且牌面均型，满贯前景还要乐观？3-正如香港大师所言，最怕同伴持 ♣AQ♦QJ♥QJ 要選擇3NT。临场时千万别忘记了，二盖一的进局选择是优于其他体系的优势，充分利用这点。If you have a choice of reasonable bids and one of them is 3NT, then bid it. Known as "Hamman's Law" 哈曼法则：如果你可以选择一些合理的叫品时，其中之一是3NT，那么就叫它！哈曼法则怎会轻易忘失呢？ 只有从心底里面对约定叫有了深刻的理解，则约定性叫牌体系才是一把犀利的战斧，否则就是一场灾难。 Quote Link to comment Share on other sites More sharing options...
