A brief Friday quiz: who, in a book published in 1985, wrote the following?
Finally I should like to say a few words about the purchase of books on openings. Volumes such as Modern Chess Openings and Encyclopaedia of Chess Openings can give a useful overview though books covering just one variation are a different kettle of fish entirely.Answer will appear in the comments box.
The authors of such books may or may not be experts in the variation they have written about. If they aren't then they will have little of interest to say whilst if they are, they probably won't want to say it.
My advice is to follow the example of masters and grandmasters who generally limit their acquisitions to a selection of Chess Informants (particularly important), magazines, and tournament bulletins. By filing the appropriate games from such sources you will have access to a more personal, comprehensive and up-to-date source of reference than any chess book could offer.
