I had learned from years of experience that when a man really desires something so deeply that he's willing to stake his entire future on a single turn of the wheel in order to get it.

我从多年的经验中学到，当一个人对某件事的渴望如此之深，以至于他愿意把自己的整个未来都押上，就为了得到它。

Now, from your original starting level of 25, you have to make sure your opponent starts on a losing level every single turn— if NIM starts on a winning level even once, it’s game over for you.

现在， 从你最初的 25 级开始，你必须确保你的对手每回合都以失败的等级开始— —如果 NIM 哪怕只有一次以获胜的等级开始，你的游戏就结束了。
