"Mr.Tanaka,how did I win the tournament with only one move?""You won for two reasons,"his teacher answered.'First,you've almost mastered one of the most difficult throws in all of judo. And second,the only defense for that move is for your opponent to catch your left arm." The boy's biggest weakness had become his biggest sterngth.

解题思路： 如下
解题过程：
一个10岁的男孩决心学习柔道，尽管在一次交通事故中他失去了左臂。男孩开始跟日本柔道教练MR. THNAKA 学习。但是在三个月的训练中，他的老师只教他了一招，男孩问道：“THNAKA 先生，难道不应该再学几个动作吗？”他的老师回答道：“这是你知道的唯一招式，但这也是你将需要知道的唯一的永远的招式。”
几个月后，THNAKA 先生带着这个男孩参加第一次联赛。这个男孩首次赢得了三场比赛的胜利，使用了他的这一动作招式。现在男孩进入了决赛。他对于自己的成功很惊奇。这一次他的对手又大又猛又有经验。裁判员想要阻止这场比赛。他的老师坚持说：“不！请让他继续。”
很快，他的对手就丧失警惕，因此男孩追问TANAKA 先生，就用一个招式，我怎样赢得联赛了呢？他的老师回答道：“你获胜有两个方面的原因。第一，你已经掌握了柔道中最难的投掷招式之一；第二，你的对手唯一的防御在于抓住你的左臂。
男孩最大的弱点，变成了他最大的力量（最大优势）。
