Player A has a payoff matrix of [1, -1; 0, 1] and Player B has a payoff matrix of [-1, 1; 0, -1]. Is this a strictly competitive game?
1
Yes, because the equilibrium strategy is in mixed strategies
2
No, because both players have an equilibrium strategy in pure strategies
3
Yes, because the sum of payoffs for both players is constant
4
No, because there is no Nash equilibrium
