In bad DB:s you >can find like 20 spellings of Kortschnoj, Viktor... > >/S In some databases progs like scid you can correct the player names automatically. The player names are compared with a player name database and corrected, if the names are ambigous or there are several possibilities you have to assist to make the corrections. It is a real pain to work through a big database like this, but TWIC updates come in handy pieces (I think monthly updates) an can be corrected easily. I like the TWIC files because they come as pgn and can be easily imported into any database, and the games are mostly from recent tournaments, so you can keep your db up to date. Of course TWIC does nort cover all the tournaments (like e.g computer tournaments), but the most important ones. - Andy
