The NE square in the middle -- actually NE, CH and QRE -- those are three different theories of Nash equilibrium, and others, tells you what the theory predicts, which is that they should match 50-50, because if you play left too much, for example, I can exploit that if I'm the mismatcher by then playing right.
中间那个NE的方块——也就是NE，CH和QRE 这是三个不同理论的纳什均衡论，或者其他 这些告诉你这个理论所预计的 也就是他们应该将50和50配对 因为如果你一直在左边，举个例子 我可以判断我是不是右边的非匹配员
