Subject: Opening Book for Engine vs Amateur Training Games

Generally, the opening books appear to have been designed to give the engine the
best possible advantage against the strongest opposition.

However, there are many chess-playing programs out there.  I am not familiar
with most of them and do not know what they all have to offer for chess
amateurs.

Intuitively, it seems to me that a chess-playing program would be most useful to
the chess amateur if the engine were to use an opening book designed
specifically for that purpose.

How do the engines select their opening moves when "dumbed-down" to play at the
amateur level?  I suspect that they use the same opening book used against GMs.
Do they?

There are many openings which could be played against amateurs but not suitable
against strong players.  Typically, they would give the engine, playing White,
just equality or worse, and might give the engine, playing Black, a slight
disadvantage.

To generalize, an opening book to be used for training of a weak player might be
inappropriate for strong players and visa versa.  There might ought to be
several different books to cover the wide performance range from beginner to
Kasparov.

All of the opening books could be combined into a single opening book but with a
different set of move probabilities for each performance level.

Do any of the programs do that now?  If not, does this look doable?  Will it
happen?

P.S. I'm still focussed on the future widespread use of chess-playing programs
as training tools for ALL human [and learning engine?] users of the software.
