     Hi!
 In the thread above I was talking to Mr. Theron about what is supposed to be
the best settings for his engine. I am not a author, but since this is a OPEN
forum, sponsored by a company that SELLS chess related things, being an author
or not is not supposed to be a problem.
 But is clear that 'en passant' my post touches an open wound in the crafty
author. Even you Jason 'the bodyguard' Williamson  must have noted that. Why a
simple mention to the crafty policies raises that anger?  If developing a strong
engine was important why he +noplayed Amir Ban? Isn't junior strong enough to
play crafty? If rating points weren't important why he +noplayed John Stanback
when zarkov was  +-2700? Of course he does what he wants, when he wants...
because he is an old man. I hope that the above helps to raise a little doubt in
you mind and prevent you from acting like "crafty zombie".
  The rest of the posts, I will answer later. Today is Sunday.
                Yours in spirit
                        Marcos Christensen
