“The only logically valid deduction in such situations is that if you follow any system or pattern in your choices, it will be exploited by the other player to his advantage and to your disadvantage; therefore you should not follow any such system or pattern. If you are known to be a left-side kicker, goalies will cover that side better and save your kicks more often. You have to keep them guessing by being unsystematic, or random, on any single occasion. Deliberately choosing your actions at random may seem irrational in something that purports to be rational strategic thinking, but there is method in this apparent madness. The value of randomization can be quantified, not merely understood in a vague general sense. In this chapter we will explicate this method.”
