We point out the strong correlation between the CP-violating asymmetries in the decays B{sup o} {yields} {Psi}K{sub s} and B{sup o} {yields} {pi}{sup +}{pi}{sup {minus}} that is predicted by the Kobayashi-Maskawa model. This results in a very restricted allowed region for the asymmetries, and so their measurement will provide a powerful test of the standard model. To show how new physics may give very different results, we look at the predictions of a simple model where both the standard model and superweak contributions to the K{sup o} and B{sup o} mass matrices coexist. We find that, for possible values of the parameters, practically any values are allowed for the asymmetries.
