zyp163 Posted May 8, 2013 Report Share Posted May 8, 2013 如果用反巴特：1H-1N2C-2H这个2H有什么用？ Quote Link to comment Share on other sites More sharing options...
dvd Posted May 8, 2013 Report Share Posted May 8, 2013 1楼，2c通常保证3+，特殊情况是4522，这个时候2c只保证2张；南再叫2n应该是承诺d有止的邀叫，不承诺均型。 2楼，2h表示弱牌示选，只保证2张h支持。 Quote Link to comment Share on other sites More sharing options...
ynhhyjb Posted August 21, 2013 Report Share Posted August 21, 2013 1、2C保证2张2、南再叫2NT，承诺4张C Quote Link to comment Share on other sites More sharing options...
