I simply order queen promotion before other promotions. So if the promoted piece is taken, the different lines will lead to transpositions and be quickly discarded. In the lines where the piece is not captured, the line with the queen on the board will yield the best material score. Then I don't understand how this can be a problem is move ordering is correct. Am I missing anything? José C.
