The main ingredients and the importance of the process D-+/- -> K--/+pi(+/-)pi(+/-) are described: its contribution to reveal the true nature of the scalar K*(0) particle, what we know about the parametrization of its dynamics, its importance for CPV in the charm physics and possible new physics contributions.
