History of chess
Full-ranging movement of the queen, along diagonals and ranks & files, is the real mark of modern chess. It is such a huge change that one French commentator called the new game eschés de la dame enragée (~ the mad queen's game), and the Italians called the game schacci alla rabioso (~furious chess).p328 Indeed, the change from a limited counsellor to an unlimited queen cannot be understood as part of the original war-game. It can only be understood as an attempt to improve the game as a sport.
