You do not understand how chess programs play openings and how they get
ELO in sweden. You simply do not understand how it works. Maybe you
don't have an autoplayer pair. Maybe you never worked on a chess
program. Maybe you are a consumer only buying the programs. Whoever you
are, you don't know how it works.
The lines NOT played are lines played BEFORE at home on hundreds of
autoplayer games. They were locked and this way the program has ANTI
books against different opponents.
NOT playing lines that are winning lines of the opponent CAN increase
the ELO.

Crafty e.g. has a big PGN-book out of human-chess-games.
But it has also a learning file where the program learn NOT to play lost
lines.
Mchess has it too. CSTal of course. Others too.
This influences the outcome of a match.

Thanks for your advise but I will not follow it.
Only because you don't understand about the concepts I will not shut my
mouth just YOU are naive.
