Not really. A statistical approach, that is, analysis of a large number of games
for frequency of words chosen, number of guesses by the opponent and if 
the opponent guessed the word, should account for strategies that include 
picking "easy" words and how well that works.

You don't even need to know the guessing strategies involved.

They'd have to know what the algorithms are, and there has to be such a 
thing as a "bad result". A statistical approach uses facts - what actually 
happened. This is hard to game. If a player picks a word that is easy to 
guess, then their opponent is likely to guess it quickly. This is especially true 
if the results from games are fed back into the learning system so that it 
can adapt to sneaky opponents.
