I don't no the code of Danchess, so I cannot judge. But I think if somebody uses the idea, a swap function looks basically like a swap function. Like an alpha-beta looks like an alpha-beta. Determine attackers, determine defenders, sort the bunch of them add up swap_scores and minimax thme in the end. As far as the eval is concerned, I agree that this is private property. regards Andy
