For me,it's a toss-up between the book on Spassky,by some guy named Van Reek(how apropo) Don't know where this guy learned his English from,but he comes off speaking gibberish. Another clunker is Idle Passion:Chess and the Dance of Death,by Alexander Cockburn,a right-wing looney who has a tremendous hatred for chess and all connected with it,but never explains why he hates the game so much. Anything by Eric Schiller is pretty much garbage. The turn of the century books by a guy named Franklin K. Young are pretty unreadable-he uses military terms to describe chess strategies. Nothing but gibberish there!
