The pawn promotion rule is not clear from this description. The point has been raised in the comments, but the author has not clarified.
In the Game Courier preset, written by Fergus, the pawns promote on the 9th rank on the a, b, g, and h files and the 10th rank on the c-f files. But in the Zillions code, written by the author, the pawns always promote on the 9th file. But the Zillions implementation is not 100% consistent either... It says "Promotion on the ninth rank is to Knight, Bishop or Rook" but it actually allows promotion to Queen and Templar also.
