The King, Knight and Rook move in the same manner as their FIDE Chess equivalents. The Archbishop has the combined moves of a FIDE Bishop and a FIDE King. The Vizier has the combined moves of a FIDE Rook and a FIDE King. They cannot capture en-passant. If they cannot move forward because they have reached the edge of the board or the Lake, they may move sideways one square instead.
Pawns promote when they reach any square on which the opponent's major pieces started the game.
They may promote to any of rook, knight, vizier or archbishop. A pawn blocked by the Lake can move in either direction. Note that a pawn can never promote on the starting square of the opponent's King, because it will need to cross another promotion square to reach the King's square. There is no castling. All other rules are as in FIDE Chess.
