Chess Maps is a learning concept for chess players, based on graphical opening trees. Large A0 posters are the real thing – it’s a complete series showing every opening in its completeness (all named variations). Smaller A1 posters are the beginner’s edition, a decorative graphic with the main openings visualized, information that most players already know. The website advertises the concept and directs visitors to the Etsy shop, where the posters are offered as a p.o.d.
