A tablebase >hit overrides *any* score. I understand that tablebases provide -MatNN,+MAtNN and draw scores but I do not understand how can you go to positions that you use tablebases at depth 12 from the initial position because tablebases are for KPP against K or KP against KP and not for positions with more pieces. You need to calculate more than 16 plies to go to positions that you can use tablebases if you do not do special extensions in pawn endings. I thought that If you can see by tablebases that the position is -MatNN because it is KPP against K then you can see without tablebases that the position is not -0.xx because the static evaluation function without tablebases is not -0.xx Uri
