Would that kind of learning be restricted to recording the best move from a variety of positions? If so then the hope of applying it would be remote. Learning on a broader scale as in human-like pattern recognition would be ominous but seems too futuristic. > >Do some of the programs out there learn in the middlegame [after out of opening >book]???????

If so, maybe we should try to purchase copies of the >programs which had been used awhile in the home of one of the top GMs. They >might have learned something not in the original program! Indeed. Or have a project where many users submit their learning files to a central area for merging and re-distributing.
