A typical example is P-f6. The first letter represents the piece moved: D = dolphin, B = blue whale, N = narwhal, G = grey whale, H = humpback, P = porpoise, W = white whale. The promoted porpoise is simply K = killer whale. The designation of the piece is followed by a symbol indicating the type of move: - for an ordinary move, x for a capture, or * for a drop. Next is the designation for the square on which the piece lands. This consists of a lowercase letter representing the file and a number representing the rank, with a1 being the bottom left corner (as seen from Black's point of view) and f6 being the top right corner. (This method of designating squares follows the Western rather than the Japanese convention.)
