More in accordance with the minmax strategy let us<br />

compute<br />

argmax si<br />

min<br />

s −i<br />

µ expected<br />

i (s 1 , s 2 )<br />

We assume Player A plays (as above) A-I with probability x<br />

and A-II with probability 1 − x (strategy s 1 . Similarly, Player<br />

B plays B-I with probability y and B-II with probability 1 − y<br />

(strategy s 2 ).<br />

We compute µ expected<br />

1 (s 1 , s 2 )<br />

thus<br />

0 · x · y + 5 6 x(1 − y) + 1 · (1 − x)y + 1 (1 − x)(1 − y)<br />

2<br />

µ expected<br />

1 (s 1 , s 2 ) = y((− 4 3 x) + 1 2 ) + 1 3 x + 1 2
