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.
"NE" kvadrat u sredini - u stvari "NE, CH" i "QRE" - to su tri različite teorije Nešovog ekvilibrijuma i drugih, koje vam govore što teorija predviđa, a to je da bi oni trebali odigrati 50-50, jer, primjerice, ako odigrate previše puta lijevo, ja to mogu iskoristiti, ako sam kontramečer, igrajući desno.
