Thanks for the shout-out! Even though I know it cheats (and how) I still play against Cheatman sometimes; the challenge is to make guesses that force the computer to bisect its search space into two approximately-even subdictionaries rather than - as it would prefer - splitting the search space into a smaller (rejected) one and a larger (adopted) one. It means thinking-ahead by about as many steps as there are undiscovered letters in the word, but it's just-about doable!
