Oh don&#x27;t get me wrong, my objection is not because I don&#x27;t understand Nash Equilibria (my PhD was in evolutionary dynamics, so it&#x27;s been a while, and I was never a game theoretician, but I&#x27;m not totally ignorant of the field). My problem is that the mathematical tools you are name checking don&#x27;t apply in this case. Even your quote itself says &#x27;changing ... strategy&#x27;, and goes on:<p>&quot;If each player has chosen a strategy and no player can benefit by changing strategies while the other players keep theirs unchanged...&quot;<p>which is not the situation in this case.<p>Strategies for infinite games are not necessarily optimal if the game is finite, and vice versa.
