I think I know what a double is, but what's a single double? In chessbase, if I select "don't copy single doubles" when importing from TWIC, it almost always finds a significant number of doubles (several hundred). Is it possible that TWIC has 2-300 doubles each issue? I'm skeptical. What's really going on? How does chessbase define a double anyway (single or otherwise)? Is it just a matching tagset between games? Who's to say that two players with the same name didn't play in the same tournament? Is it a complete match of the tags and the movetext? That would be better, but judging from the speed of similar operations, that's probably not happening. Is chessbase checking for doubles in the database to which I'm importing, or is it just checking for doubles within the file being imported? If chessbase is checking for doubles within the target database, how does it know which to keep? Personally, I'd want the annotated one, but it doesn't ask me. What if I have 5 different annotations of Byrne-Fischer, 1956.10.17 and I drag a few hundred games over that includes a 6th? Will it omit the 6th? I'm a database programmer and I just can't stand feeling like I'm not in complete control of my data. Confused Regards, - mark
