Hi Melvin:
Very amazinbg that a man from a company that failed to match Lang programs due
to be stucked with the non selective approach by the Spracklen team now say that
non selective technique is the better one. Yes, less risk of oversighting, BUT
only inside a narrowed horizon. On the contrary, brute force by neccesity
involves shorsightedness for long shots, strategical problems where you cannot
see if you do not see 12 plys or more. Every current top program is more or less
selective and I cannot imagine a better proof of the superiority of the
technique. Nevertheless, maybe we are talking in a somewhat too wide manner as
much there are many variations of selective technique according of how much
selective they are and how they do so. Bob Hyatt could say something a lot more
substantive about this controversy.
Greetings from Chile, that has nothing to do with Ecuador.
Fernando
