Antoine Fourriere mis-reads Larry Smith's idea, which I agree with, that
potential for advantage in the exchange comes from significant differences
in piece values, regardless whether many an exchange may appear equal. I
incorporate these piece-value disparities numerically in what is called
Exchange Gradient. In Antoine's words, 'a useful variable' of 'over-all
strength by piecetype variance' is exactly what EG is.
