I'm still not convinced of the usefullness of book learning. I don't know how many programs have "hash learning" like Nimzo99. But with book learning, I haven't seen an explanation of how it works so I can't put it down too much. The thing is, with todays programs which have hundreds of thousands of book moves which make up several thousand variations, they can play a different variation everyday for the next ten years and not repeat. In that case what good does it do to learn not to use a particular variation again? I guess I'll have to wait for Dr. Hyatt's paper to ICCA. Jim Walker
