Hiarcs and Fritz re-weight their opening preferences based on their prior success or failure in various openings. For example, if you play Hiarcs (or Fritz) 10 games in a certain branch of, say, the Sicilian, and it beats you all ten games, it will probably tend to prefer that branch over all others. This branch might be a *great* line to play against you (posibly due to your lack of familiarity with that opening), but it might be a lousy opening to play against another computer program or a very strong human opponent. By resetting the weights, you restore the tree to its default setting (making Hiarcs or Fritz "forget" its previous results in that line). See section 4.6 "Book options" and section 4.7 "Reset weights" in the Fritz5 manual. >After >copying the Hiarcs opening tree to the hard drive, why would it be necessary to >repeat the process? You don't have to repeat the process. "Reset weights" has absolutely nothing to do with recopying the book to the hard drive. -- Steve Lopez
