    You are given that the optimal column strategy is [1/2, 0, 0, 1/2, 0, 0]. Any optimal row strategy must be optimal against that so you really only need to consider the first and fourth columns. (I get, as optimal row strategy, [1/2, 1/2, 0, 0].

    I tried that but then i can't show that L(x,y)=w=5/2 which makes the game unfair. If i use Rowboy's strategie as [1/2,1/2,0,0] i get the game is at w=3/2 which doesn't equal to 5/2. I know that is a feasiable strategy but its not optimal.
