Go up one level in this thread


Computer chess program are suppost to be designed to examine the board and guess
at what the move should be based upon weight and rules. Using an opening book to
make move is altogether another thing. First lets define what is an opening? Is
it the first 5 moves; 10 moves; how many are considered opening before you get
into midgame or endgame? The first 5 or 10 moves of a chess game can play a big
part of how strong a program can be, that is if the moves selected are good
moves. If one side develope a strong control of the center and the other side
does not in the first 10 or so moves then the second program, no matter how
strong the engine may be is at a great disadvantage and might lose.
Last year, or maybe it was in 2000 there was a tournement held and the results
were posted in this forum. In one game, one program checkmated its opponent
without ever leaving its 'opening book'. I complained at that time and several
times since. I thing that the size and depth of opening books should be limited,
at least in competition games. What they sell for private use by the home user
is another matter completely. Some people want the strongest program that they
can get period, but even there I would bet that some people would love to be
able to disable the games books once in a while.
Those people who have strong opening books have one point of view and those who
don't must have another. ect. ect. ect. I have said this all once before and now
I am repeating myself again.
