Some time ago I downloaded there a database (b00-b99) that allegedly has more than 700k games. Then I searched for B85 (Scheveningen), a line in which I'm particularly interested. Well, a famous Karpov-Kasparov game (Gary won after a fine positional sacrifice of his b6 pawn) is no less than three times there, and only one of these "versions" is right, one is short and full of absurd moves (not illegal, just ridiculous, both players makind absurd blunders all the time), a second one is correct but short (some 25 moves, more or less), only one is correct. Question: how many absurd games are in that database? Moreover, to study -say- the Sicilian I also want to have very old games, those played by Euwe, Maroczy, etc. At least, I want to have all the Sicilians played by Najdorf! None of these are there!! That database has only recent games. For a human player that's a turnoff, as history is important in order to rally understand an opening. So, I guess Lunsen databases are of little use to study openings. Also, if the opening book is related to those databases, it could have many absutrd lines as well. So, it's useless. I deleted the downloaded database, and decided never more visit that webpage, until somebody tells me that they now have purified their databases. Telmo
