Sorry, I thought you were, so I did. I don't think you'll get any alpha-beta cutoffs if your evaluation function only returns 0. >Are your alpha and beta values set to + and - infinity in this test? No, I use alpha-beta windows. I also use null windows. >Why are there 2 lines for each ply? The first line is when the search finds the pv for that ply. The second is when the ply is finished. -Tom
