Showing your hands more when you talk with someone is the way to go.

当你和别人说话时，多把手伸出来是一种很好的方式。

But filling the gaps by talking a bunch isn't going to give you any more control - you're just showing your hand without getting anything in return.

但是说一大堆话来填补空白并不能给你更多的控制权——你只是在说废话而没有得到任何回报。

Like, people have lost the opportunity to - you know, you're not supposed to show your hand, or you're not supposed to cry at work.

就像，人们失去了机会——你知道，你不应该举手，或者你不应该在工作中哭泣。

We also use this expression in normal conversation; to show your hand means to tell other people your secret plans or intentions, often when you are not yet ready to do so.

我们在正常对话中也使用这个表达方式；展示你的手意味着告诉别人你的秘密计划或意图， 通常是在你还没有准备好这样做的时候。

Since the two of you are competing – you each have to come up with your own plan – neither of you wants to show your hand before you give your proposal to your boss.

由于你们两个在竞争——你们每个人都必须提出自己的计划——你们都不想在向老板提出建议之前亮出自己的牌。
