This makes sense for some special positional exercises and maybe for some endgame database. This isn't a general solution - for example, it doesn't help for tactics.

Anyway I will leave classification to database creator. If it is done by custom PGN tags, it can easily be added automatically by external tool if classification for given database makes sense. >Anyway, the biggest problem, IMHO, will be with the headers.

For training you may practice only Vancura position or all rook endgames in database - then you won't be given tip about Vancura position. -- Michal Rudolf ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
