Hello
I hope I explane this well , here goes.
Engines come with external files(books & tablebases) that make moves accross the board without the engine's help. My idea is If external forces govern oppenings & endgames, can an external file hold positions many ply deep that could arrise from a large book or Endgame file but instead holds JUST positions! way into a game not connected with oppening books or endgame files. It would be a middlegame book, you would never get all the positions in it but as new info comes up against say another engine you can fill it with a killer resonce NOT derived from a oppening book.
so what Im saying is; middlegame file filled with problem positions and responses, it would push chess engines to develop random play, and I think it would be a good thing.
Anyway what do you think?
