I got that from the book "KING HUNT" means the king forced to move from the side of the board to another just like that one!!
the "Dutch Defense"

Lasker and Thomas were not GMs becuase the title did not yet exist when they were on the scene. They would be if they were alive today. This game is one of the most memorable king hunts ever. There have been some questions regarding the correct game score over the years, however. See "Chaos in a Minature."
Ziryab, Lasker (Emanuel) is the record holder for consecutive years as world champion. Who cares if he wasn't a "gm"?
