In my work with databases and older games, I've come across lots of strange and false games. These are to be found also in commercial DB:s. If these games automatically are used to make books for engines, the result can be both weird and bad. Below a small sample of games from a commercial DB of a rather good reputation. If you take some time and replay the games, you'll know what I mean... These games differ so much from the real ones, that normal dup-search just won't find them.
