1m-p-1M-?

1-p-1-2

1x-p-1y-1NT

1.否则拿着大无将没法叫了
2.应叫人尺度越来越轻，你不能afford被对方轻易偷走一个部分，结果发现你们还有局。

OK.这个逻辑下的答案很明确。技术性+平衡性

2D表示自然叫，即使对方保证4张套，没什么呵？你2S不也已知对方黑桃套保证4+么？
2H表示自然叫，反正我没碰上过，但似乎保留自然叫也没什么，因为你也想不出有什么必要这里安置一个“高妙约定”，打个一万年，万一人家诈开1H呢？你不自然叫不就干瞪眼了？

1H-p-2H-4H

1- 可以视体系和搭档间的具体约定而定。
2- 定义为自然叫或更好的约定叫，各有得失。
3- 既然敢于二阶自然叫，根本就是不惧怕应叫人所应叫的高花，因为这时候争叫人持有好的长的高花套，最具描述特点的也只能是看着自己的本手叫牌了。

1C-1S-x-p
2S，自然叫，有套出套没什么必要这时候就来个扣。
1C-p-1H-1S，或1C-1S-2H(直接出套8点以上）-p
2S，自然叫，有支持直接加，没什么必要这时候就扣叫显示“好好的支持，好好的牌”

============================================================

1C的“多义”性，决定了你得根据对手1C的意思,决定你的2C是什么。

============================================================

1D同样与1C稍有区别。但同样有各种情况会使你的2D意思不一样。

============================================================

============================================================

1H开叫后与这个道理相同，可保持自然叫，但会很少用到。

1C开叫保证2张，我打过，实际上只有一种情形——当且仅当4432（好处是换回1D开叫保证4张），其他几乎跟普通叫法没有任何区别，没有什么特别高深的。

F-N的所谓“自然叫”又另当别论，他们所有的一阶开叫保证14点以上，逼叫！即他们打zr51xF！所以他们的一阶实际上承诺比“普通开叫”强一个K的力量，那你处在第4家，是否要卷入当然要掂量掂量，因为开叫者完全可能持比普通开叫强得多的手坐你后面。
