Subject: OPENING BOOKS

I am convinced that with a more extensive use of the available chess engines on
exploring opening moves the whole theory could be rewritten and surprising new
moves could be discovered.

If you let the computers calculate from the beginning just the 2 best moves in
each position for each side you will arrive at more than 1 billion positions
after the 15th move (2^30 = 1,073,741,824 positions)!

That are 100 times more positions than the largest opening books have and yet it
would be a very limited book because some of the most popular lines would not be
covered (e.g. after the 1th move you could arrive - depending on your engine and
time allowed for calculation - at the following four positions: 1.e4 e5; 1.e4
e6; 1.d4 d5; 1.d4 Sf6 from which the tree would expand. In this case you would
miss the Sicilian completely).

And if you would take the 3 best moves you would arrive at 205,891 billion
positions after the 15th move!!

I think it would be worth to let the computers analyse as much as possible and
probably it would be necessary to organise a search via internet to have the
greatest benefit from their anlysis power and to achieve as much analysis as
possible.

Let’s say it would be necessary to let the computer calculate at least 1 hour to
find the two best moves than 61,287 years would be necessary to reach 1 billion
positions. Or 61,287 chess enthusiasts would have to let their computers analyse
one full year. A daunting task!
