这种游戏的玩法是,取任意数目的筹码(可以是硬币、棋子、石子或小纸片等),把它们摆成一个圆圈.两位游戏者轮流从中取走一枚或两枚筹码,但如果是取走两枚筹码,这两枚筹码必须相邻,即它们中间既无其他筹码,也无取走筹码后留下的空当.谁取走最后一枚筹码谁获胜. 如果双方都玩得有理,谁肯定能获胜,他又该采用什么样的策略呢? The game is played by taking any number of chips (can be coins, stones, stones, or small pieces of paper, etc.) and putting them in a circle. The two players take turns taking out one or two chips, but If it takes two chips, the two chips must be adjacent, that is, they have no other chips in between, and there is no space left after the chips are taken. Whoever takes the last chip and who wins. If both sides play Reasonable, who can certainly win, what strategy should he use?
