The white pieces are placed on the first and second ranks and the white pawns are placed on the third rank as shown in the diagram. The white rooks alone are placed on the first rank, which makes it easier for them to activate earlier in the game since they are not blocked by the other pieces as they are in standard chess. The black rooks are placed the same, for the same advantage. Black's pieces are placed on the ninth and tenth ranks, and the black pawns are placed on the eighth rank.
A white pawn may elect to either promote or remain a pawn upon reaching the eighth and ninth ranks, but must promote upon reaching the tenth rank. Unlike standard chess, a pawn may be promoted only to a captured piece of the same color, so it is illegal for either side to have two queens, or two marshals, or three rooks, etc. If no captured piece is available for promoting a white pawn about to reach the tenth rank, the pawn must stay on the ninth rank, but it can still give check. This is not as strange as it appears, since pinned pieces can still give check in standard chess.
Similarly, a black pawn promotes optionally upon reaching the third and second ranks, but must promote in order to move to the first rank. It can still give check from the second rank to a white king on the first rank, even if it can't yet legally move to the first rank.
As in standard chess, pawns can move one or two squares on their first move, and they may also capture en passant.
As in standard chess, checkmate is a win and stalemate is a draw. There is no castling in Grand chess.

Famous quotes containing the word rules:
“One might get the impression that I recommend a new methodology which replaces induction by counterinduction and uses a multiplicity of theories, metaphysical views, fairy tales, instead of the customary pair theory/observation. This impression would certainly be mistaken. My intention is not to replace one set of general rules by another such set: my intention is rather to convince the reader that all methodologies, even the most obvious ones, have their limits.”
—Paul Feyerabend (1924–1994)
“Let’s start with the three fundamental Rules of Robotics.... We have: one, a robot may not injure a human being, or, through inaction, allow a human being to come to harm. Two, a robot must obey the orders given it by human beings except where such orders would conflict with the First Law. And three, a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.”
—Isaac Asimov (1920–1992)
“This was Pharaoh, direct descendent of our deity Amon, god of the sun, who rules the heavens as Pharaoh rules the earth. Again, he brought treasure, gold, and precious jewels taken from our enemies. For to Pharaoh riches were power and power was to be desired. And also again he brought many captives. For is it not by slaves that one becomes even richer and then has even more power?”
—William Faulkner (1897–1962)
