muronghan Posted April 16, 2017 Report Share Posted April 16, 2017 第二家不是教科书式的技术性加倍吗? Quote Link to comment Share on other sites More sharing options...
sfbcs Posted April 19, 2017 Report Share Posted April 19, 2017 1.1S争叫可以接受2.可能会X的,随手放pass的可能性也比较大3.X的可能性很大,不太肯轻易pass的 Quote Link to comment Share on other sites More sharing options...
lxt08 Posted February 14, 2018 Report Share Posted February 14, 2018 议题:1、第2家争叫1S2、第4家应叫3、第6家平衡叫 第二应该叫加倍,这样叫到3C很正常。2、3问题 相信同伴 不叫。防止失配。 Quote Link to comment Share on other sites More sharing options...
2200 Posted March 7, 2018 Report Share Posted March 7, 2018 1.教科书会告诉你说,技术性加倍是拿着敌套短门、三花(至少两花半)都能支持同伴时,而不是现在这样全手呆型,全是防守点;2.北pass后,一般打建设性加叫的搭档,持东会定义为低于建设性加叫,即先1NT逼,然后准备回2H;3.东1NT逼叫后,如果南胆子大点(six-four, bid more),可以介入2C,南的力量,只此一叫,此时不介入,永远就别介入了,后续会变成东西打2H,南北正常防守拿100;4.北埋伏着14点,南既然敢于介入,当然会有3NT想法,但不至于逼局,邀到三阶总是够的;5.南北如果这样介入,叫到3NT也很正常,但是正常防守下不难下掉,这是正常的博局,我认为可以接受。 Quote Link to comment Share on other sites More sharing options...
