But I think the values >won't balance out (unless you meant material score, or something) in SEE I meant that I am using the same piece values for material score as I am using in SEE. When I do SEE, I just use an int, so that should be fine, but as the same values are used for material score, which I use in evaluation which eventually ends up in hash entries, I want the material scores to not be too big. I already use many bits (18) for storing the score, because in this version of Chezzz, I am using millipawn values instead of centipawn values (I want to experience myself that millipawn precision is not worth the effort before switching back to centipawns). >calculations. Are you storing the SEE score in hashtable?? I believe SEE score No, I am not... :) >should be used only to sort the moves, and nothing more. I agree. >I think you are tired, >or then I'm _very_ tired ;) Or are you using the same king value for I am not especially tired. I slept 11 hours last night :) >calculating >material balance? Then you are right: the values will of course balance out. But >overall, in material calculation, you can just skip kings, right? > >Severi Sure. But to make things simple, I skip have been skipping the king by assigning it a value of 0. /David
