The first hand is another great example for balanced principle. Before the first bid, south should picture that if they have a fit and partner has a red singleton, then there is a thin slam possibility. So rather than showing a 4-4 M to partner, you ask partner for his (approximate) shape instead, like what your quoted precision sequence do. The problem is not fully related to the system, but rather one need a artifical balanced FG bid.


The second hand is a typical difficult hand to bid - any 2 running suits slam with the other two suits controlled is difficult. The key fact is whether south can introduce his ♣Qxxxx suit as a potential source of trick oppose to a strong partner. In many case this is difficult, and the club suit here make it more difficult to introduce - you need to bypass the 3NT to show it in your example.

其实，标题也可以写成：《转2副二盖一体系不容易搞定的牌》

原有的标题关键词是：精确
改后的标题关键词是：二盖一

我还是看好原有的标题。

两幅牌应叫人都没有显示出实力！ 没有一个试探的过程！

麻烦你写出一个试探的过程，显示出实力，可以吗？
