Some comments concerning the game:

QUAAK! is a very simple
game of bluffing (the publisher created it for childs in the age from
7 to 12 years).
The computer is using a (randomized) mixed minimax strategy. The general existence of such strategies for all twoplayer zerosum games was first proved by the famous mathematician John von Neumann in 1928. The strategy was computed recursively using the so called simplex algorithm for each round. Details are described in chapter 44 of my book "Luck, Logic and White Lies: The Mathematics of Games" (preface and contents). The strategy is optimal in the sense that you don't have any bluffing strategy which is favourable against the computer in the long term.
