(Update 25-8-2024: From now on, we will include everyone who is a Krachtschaker (has played Krachtschaak games/solved puzzles), but has not yet played an official rated tournament, whom we remember to be one, and whose name we know, on this list as well, but as 'unrated'.) (There are many more people who only know the rules, but we will not include them.)

Blitz ratings are based on K-40 at the William Invitational tournament. The starting rating there is your Krachtschaak Rapid Rating, but if you did not have one yet, your KNSB Rating was used.
