This is a wonderful project of mine. Chess Maps are variation tree posters that help you learn chess openings.

A Chess Map displays all (ok, almost all) named opening variations with their name, a diagram and paths to parent and child variations. 

You can buy them at

Altogether there are 3000+ named variations on 22 Chess Maps

To explore them, start at the bottom end of each map and with every move go upwards one row. Where the path splits into two moves or more, you will find the options arranged like on the chess board: From left to right, e.g., a move to a3 is on the left, then c4, and Nh3 appears on the right end of the fork.

Those long paths reaching the top edges have their extensions displayed in a separate window, in the manner of outlying islands on a map. Arrow numbers above some diagrams point to pages with separate opening systems (missing the Nimzo-Indian and the King’s Indian here? they need separate pages).

Chess Maps are meant to be a learning resource for chess opening terminology. When you follow a path from diagram to diagram with your finger you attach a physical experience to the learning process. This helps your brain remembering the variation names, their geographical position in the tree and thus the way to get there.

To limit complexity, every variation appears only once and in the context of its normal opening system. Alternative move orders and transpositions are not reflected. Also not reflected are second or third names of some variations. I just went with the one that appeared to have a majority of hits in online chess databases.
