Be clear about not LMR the ttMove Currently a ttMove is reduced with ss->reduction = DEPTH_ZERO, so it is actually not reduced (as it should be), but the trick works just becuase it happens that ttMove is the first to be tried and reduction(depth, 1) Always returns zero. So explicitly forbid reduction of ttMove in the LMR condition. This is much clear and self-documented. No functional change.
