Mathematical basis would be nice, of course. I manually entered opening book analysis (including many middlegame positions, of course) from a couple of books in wildly different opening systems into Bookup for Windows. My experience is that the cutoffs for the Zarkov 4.0 engine that is integrated with it were (0.00 to 0.35) equal game (0.35 to 0.85) slight edge for white (0.85 to 1.35) clear advantage for white (1.35 to +oo) decisive advantage for white and the appropriate mirrored scores for black. I don't have any information on the endgame for you. (I wonder if John Stanback will release an upgrade for Bookup users to a newer version of his program?) Dave Gomboc
