english: 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.
non_english: NE kvadrat v sredini - dejansko NE, CH in QRE - so tri različne teorije Nash-evega ravnovesja in drugih, ki vam povejo, kaj teorija predvideva, torej da bi oni morali odigrati 50-50, ker, če levo igrate prevečkrat, na primer, jaz to izkoristim, če sem neujemalni in odigram desno.
