Mr X

The chess federation celebrates its 150th birthday this year. One of the special things they organize is “mr X”. Mr X is a chess player who is probably known by many people, but we have to guess who he is. He shows up at many different places and tournaments, and if you are lucky you can play against him. And maybe you know a bit more if him afterwards… Today he was here at the youth championship. One of the girls had a special outfit to play against Me X.
