Recall the game between R and D determined by the following data.
Here is Ashby’s analysis of how it plays out.
Examination of the table soon shows that with this particular table R can win always. Whatever value D selects first, R can always select a Greek letter that will give the desired outcome. Thus if D selects 1, R selects β; if D selects 2, R selects α; and so on. In fact, if R acts according to the transformation
then he can always force the outcome to be a.
R‘s position, with this particular table, is peculiarly favourable, for not only can R always force a as the outcome, but he can as readily force, if desired, b or c as the outcome. R has, in fact, complete control of the outcome.
