I think this is one of the issues, where big improvements could be made... I imagine learning data pools for each program, with users being able to upload their individual new learning data, and download huge amounts of that. Maybe those are organized by depth it was calculated at, openings or whatever. Or users can exchange that data with each other, and add it to their own files, etc. Probably this idea is limited by the quick release of new versions also among the pros (once a year or so), so that the old lerning data would be outdated soon and not be useful anymore, when a program has been changed. But it's still interesting, also the update cycles seem to take more time now than in previous years. Does the Crafty learning data contain only positions and their evaluations, or is there a kind of performance stamp added? I assume the search depth is included, at which the info was produced? I'm sometimes not quite sure with other programs, if they avoid using data from i.e. blitz/9 plies also when they play at 40/2h and could probably reach 3 plies more to reconsider. Usually, the docs don't go into details that deep. But I think that problem should be solved (?). Regards, Mike Scheidl
