A question occured to me.
Methods of capturing are taken from non-chess board games.
Everybody know the family of games, overtaking from is.
Custodianship is from Tafl games, probably also well-known.
Withdrawing, if i did not confuse anything, is also from some checker-like board game (i don't remember it's name, region and time of playing).
But what about coordinating? Is it also from certain board game or invented by Abbott himself? And, maybe, immobilizing is also refrence to certain game?
