Or is there some unimaginable way in which to get a >better ratio for promotions? You take one pawn with a pawn to promote 3 pawns (1 pawn of the color captured, 2 pawns of the capturing pawns). For example, the white a pawn takes the black b pawn and then the two white b pawns promote and the black a pawn promotes. Hence, worse case, you give up 16 pawns and gain 12 promoted pieces. Since in the Huffman encoding mentioned, pawns take up 2 bits fewer than pieces, you actually gain bits when promoting pawns (with this type of scheme), even though you have to give up one pawn in order to start the promotions.
