Rock, paper, scissors is an ancient game of cunning and chance.

剪刀石頭布已流傳許久，是詭詐且碰運氣的遊戲。

If only there was a way to improve those chances.

真希望有方法可以提高贏的機會。

Turns out there are a few key strategies.

還真的有幾個關鍵策略。

The game is mainly about predicting and reading your opponent.

猜拳這個遊戲主要是預測跟解讀你的對手。

So, what if you could predict their first hand?

所以萬一你可以預測對手的第一拳呢？

Research has shown that there is a slight preference for people to begin by playing rock.

研究指出人們略為傾向一開始出石頭。

There are different theories about why.

有不同的理論可以解釋原因。

It could be because it is mentioned first in the name of the game, or it could be because rock is similar to a fist which seems powerful.

可能是因為遊戲的英文名稱中，石頭是第一個被提及的，或是因為石頭看似象徵權力的拳頭。

So if we know that, it gives us an edge—just play paper.

所以如果預先知道這一點，我們就佔了一個優勢──就出布吧。

Research shows that people who lose a hand tend to change.

研究指出人們輸了之後，下一局會出不一樣的。

So there is a reasonable chance that our opponent will change to scissors or paper.

所以我們合理推測對手會換出剪刀或布。

That gives us our second edge—just play scissors and we should either win or draw.

這給了我們第二項優勢──出剪刀就好，我們不是贏就是平手。

But this isn't an exact science.

但這不是準確的科學。

What if it doesn't go to plan and your opponent wins?

如果計劃不如預期且對手贏了怎麼辦？

Perhaps they know a bit of game strategy, too.

或許對方也略懂猜拳的策略。

If we lost the previous hand then our opponent might reasonably expect us to switch to something else.

如果我們在前一局中輸了，對手可能合理地預期我們會換出其他拳。

This gives us our final edge—surprise them by sticking with our previous choice.

這給我們最後一項優勢──出同樣的拳，讓對方措手不及。

Hopefully they'll switch, expecting us to switch, and it should improve our chances.

希望對手在預期我們換拳的情況下也會換拳，增加我們贏的機會。

The less predictable you are, the better chance you have of winning.

對手越摸不透你的策略，你就越有機會贏得勝利。
