An higher order approach would be to look at probabilities for chains of letters. E. g. in English the chance for an 'u' should be higher than average after a 'q'.
That's the wrong way of approaching it. One shouldn't look at the frequency of chains of letters in the particular language - but to the frequency of chains of letters in the list of words that may possibly match. But then, I don't see when this algorithm gives you any better guesses than looking for the letter which occurs in the most words. If for instance the current guess has a 'Q', then almost any word in the list of possible matches will contain a 'U'.

Now, I'd be surprised to see an efficient hangman guessing algorithm to guess 'Q' before guessing 'U'.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
