We’re looking deeper into the amazing MillionBase database with over two million chess games to see what else we can learn about the data specifically, and possibly about chess in general. I have analyzed some of this data in Part 1. If you haven’t seen that, feel free to give it a read. This post will focus on other aspects of the data, and I have drawn from some reader suggestions from the previous post.

I wanted to do something like this for a long time, and finally I think it’s at a point where I can release this into the wild. We’ll take a look at more than 2 million games, taken from the MillionBase PGN database. I ignored any Chess960 games contained, but in total there are 2,197,113 games. I was interested to see what kind of visualizations I can do, and what patterns would be revealed by considering so many games.
