arter Posted January 23, 2013 Report Share Posted January 23, 2013 我选1S。同伴pass。我争取超两个。 同伴叫1NT。我叫2NT。 Quote Link to comment Share on other sites More sharing options...
lycier Posted January 23, 2013 Report Share Posted January 23, 2013 这道题是一个难题。我觉得不论如何开叫---1♠还是2nt，都瑕不掩瑜的，都有丢局的时候。 Quote Link to comment Share on other sites More sharing options...
arter Posted January 23, 2013 Report Share Posted January 23, 2013 如果两套是低花。怕就是开2NT了吧？ Quote Link to comment Share on other sites More sharing options...
nathan2008 Posted January 23, 2013 Report Share Posted January 23, 2013 2nt , 如果前面落后了要拼的话开2c，准备 2nt. Quote Link to comment Share on other sites More sharing options...
000ffj Posted January 24, 2013 Report Share Posted January 24, 2013 开叫1s是肯定的，当你看了下册中很多1M-1n-2N（52页例46）牌后，你甚至会觉得你的这种加叫牌力还稍显不足，有一种冒叫的感觉，因此完全不需要担心开叫1s叫低了。 Quote Link to comment Share on other sites More sharing options...
lycier Posted January 24, 2013 Report Share Posted January 24, 2013 当手中持有半壁江山时，有的时候，牌情是很微妙的。比如：你开叫1♠吧，同伴持有： S:XXH:KXXXXD:XXxC:JXX 好了，开叫1♠后，opp连带同伴都会有可能pass，结果是丢局的。这也就是因为这个缘故，持20P均型含五张高花不敢开叫一阶的原因所在；而持非均型时，别人争叫的可能性也会大增，开叫1S也更有理。 Quote Link to comment Share on other sites More sharing options...
3ntmk Posted January 27, 2013 Report Share Posted January 27, 2013 在我的概念中是不考虑5-4套开2nt的。尤其是s5-h4。 如果能接受开叫2nt，唯一的因素是DKx。 担心开叫1s会丢局是可以理解的，但开2nt宕3也需要谨慎。 Quote Link to comment Share on other sites More sharing options...
wuhuan Posted January 27, 2013 Report Share Posted January 27, 2013 学习了54或45高花套不在开叫2NT的范围内可以这样理解吗？ Quote Link to comment Share on other sites More sharing options...
