Three different people have pointed me to this post by Ken Regan on statistical evaluation of claims of cheating in chess. So I figured I have to satisfy demand and post something on this. But I have nothing to say. All these topics interest me, but I somehow had difficulty reading through the entire post. I scanned through but what I really wanted to see was some data. Show me a scatterplot, then I’ll get interested.

P.S. This is meant as no disparagement of Regan or his blog. I just couldn’t quite get into this particular example.
