Query: Great book but poor printing....

I agree with other reviewers - this is probably the one book to get if you are a serious chess player seeking to get the edge in the endgame. It's advanced, so beginners might find Pandolfini's Endgame Course a good introduction. My only gripe, shared by others it appears, is the quality of the printing. The blue sections, which illustrate the essentials, vary from clear to faint. This is obviously deficient quality and needs fixing for the next print run. It's a pity as the book is intended to be studied, immersed in and pondered on.
