Zimmermann I agree that depthes of different programs are not eqvivalent but you can compare the rating of Deep Fritz(6 plies) with the rating of deep Fritz(5 plies) Yoiu can also compare the rating of Deep Fritz(10 plies) with the rating of Deep Fritz(9 plies) If you see that the difference is smaller when the depth is bigger than you can learn that there is deminishing returns for Deep Fritz. Playing the same program against itself is less convincing. Uri
