infoDisable post null-move trick in the search when 3 or less pieces are on the board, since tempo is accounted for in specialized endgames evaluation. This could make some difference for detecting stalemates or zugzwang in KXK endgames. Now with the correct inequality. It did not change the bench because no KXK positions are reached in bench.
