Remove moveCountPruning in search.cpp The definition of moveCountPruning may cause confusion by implying that the variable is unconstrained. However, once it is set to true, it should not be reset to false, otherwise it would break the internal logic of MovePicker. Several patches have overlooked this constraint. For example: https://tests.stockfishchess.org/tests/view/671e7c0486d5ee47d953d226 https://tests.stockfishchess.org/tests/view/66a1de7b4ff211be9d4eccea The implementation approach was suggested by Disservin.
