And if yes, what is its special purpose? And one other thing I´m still confused about: Since a long time now I´m really impressed about King´s ability in solving mate problems very fast. The only thing I don´t like is, that almost everytime TheKing first finds deeper solutions than necessary, and eventually finds a shorter (or the shortest?) mate after some further calculation. So I had the idea to set Kings selectivity to 0 (sel=0), and I hoped to get _only_ the real _shortest_ mate - but without success! Also with sel=0 TheKing still seems to calculate deeper than its actual depth. Now my question: Do _I_ think ´wrong´ here (that sel=0 should work), or doesn´t take TheKing this setting as strictly as I would believe? Best regards, Franz.
