re:Fritz 7 and Opening Book - 2006/12/21 08:47
If you import games to your opening book, you actually add moves from games to the opening tree, and the statistics of those games (results, times played etc.) are added to the database.
If you import not only the actual game moves, but analysis as well (if it is available), the moves of those variations (the analysis) will be physically added to the tree as well, but no statistics are added (of course not: an analysed line has nothing to do with the actual play and the actual result).
If you let the opening book learn from a database, it does _not_ import moves from games, it just looks up the game moves, checks them with the moves already in the book, and adds just the statistics to the tree (number of times played and success rate).
So:
1. importing games = importing moves and statistics
2. importing variations/analysis = importing moves but no statistics
3. learning from a database = importing no moves but just their statistics
If you don't want to enlarge your opening book but just want to improve the stats, let it learn from a quality database;
if you want a hughe opening book with a lot of variations and transpositions and their results, just import the games;
if you're not interested in stats, but just want a big opening tree, include the variations/analysis as well..

Errors of haste are seldom committed singly. The first time a man always does too much. And precisely on that account he commits a second error, and then he does too little.
