The interplay between antiferromagnetism (AF) and superconductivity (SC) in cuprates is studied for the two-dimensional Hubbard model with a diagonal transfer t 0 , using a variational Monte Carlo method. Optimizing an improved function for strongly correlated values of U/t, we construct phase diagr
