Yes, but since he knows this line well it does not means he would play the best move even if he knew it.

Trivial too. >If we had a *very* good book, we wouldn't need an engine. Well, a good book cannot include all moves, but maybe the most important ones that a chess engine may not be able to find or would play weaker moves. >Solving the book problem sounds like solving chess. Of course not. That would mean to include a huge amount of moves, but to find the best moves is quite difficult and takes time or a very good system... > >You think it is possible?
