Probability of each chess piece being moved on move X
GOING FROM ONE CHESS PLAYER TO MANY CHESS PLAYERS
We were wasting time on the internet one day an saw a post entitled Probability of a chess piece being moved on move X in a Vassily Ivanchuk game. It featured this graphic.
We then thought, “this post involves chess and data. Let’s send it to Ashton Anderson, who loves chess and data.”
Ashton wrote back.
Ashton: Ha yes, I saw this! Would be nice to have the diff between Ivanchuk and the average game. “Chucky”, as he’s known, is the mad genius of chess, but I doubt it manifests itself in what move number he moves particular pieces.
Decision Science News: Good point. Just thought it was an interesting way to visualize things. Would be best IMO as an aggregate over all (good) players.

Ashton: Good idea!
[then he posts the image below, which he computed incredibly fast]
Source is All professional games where both players are rated at least 2500 (grandmaster-level) from ~1950 to 2015 (214,000 games).
Decision Science News: That was fast!
At that point, we got permission to blog about this.
