In a two player game, a Nash is a "stable" pair of strategies (S1, S2), where player 1 uses S1 and player 2 uses S2. "Stable" means that if one of the player's uses their Nash pair, then it is always in the best interest of the other player to use their pair. Assuming they are "rational" then the second player is "forced" to play a certain way if they know the other play is following the Nash. A Nash is not necessarily good for either player. For example, in the Prisoners' Dilemma, the Nash is for both prisoners to defect, which leads to a long prison term for both prisoners. |
