We give ansatze for solving classically the initial value constraints ofgeneral relativity minimally coupled to a scalar field, electromagnetism orYang-Mills theory. The results include both time-symmetric and asymmetric data.The time-asymmetric examples are used to test Penrose's cosmic censorshipinequality. We find that the inequality can be violated if only the weak energycondition holds.Comment: 16 pages, RevTeX, references added, presentational changes, version  to appear in Phys Rev.
