There's no need to fly off the handle. What I said does not contradict what you said. I was just pointing out that, using the method you stated above, in order to get a separate PGN file for each and every in a database such as Mega99 would require one to perform your procedure 85,000 times. Assuming 20 seconds per player (which I feel is a radical lower bound, considering that one has to create a PGN output file, select the games from a sorted list, and export the selected games), you're talking, at a bare minimum, 472 hours, just short of 20 days. 20 days in front of the computer. And you'd have to do each operation 85,000 times. The beauty of a batch operation (such as a modified version of PGN extract would be presumably able to do), is that one can set it, kick it off, and come back later. It could probably do the job in a few hours at worst, because it doesn't have to deal with a UI and being controlled by a person using that UI. BTW, I have Chessbase 7.0, just haven't used it recently, and I never bothered to update it. That, however, is irrelevant to my analysis of your suggested procedure. Chessbase is a extremely useful tool, but it wasn't designed to do everything. Different tools exist for different purposes. If Chessbase does have a batch mode where, with ONE operation, it can split the MegaDB, for example, into 85000 PGN files, each file with all the games by a single player, white and black, then I'm wrong and I'll cheerfully admit it -- but your procedure given in your note above does not address that issue. -- Randy Shane
