We consider the effective extended Hubbard Hamiltonian for the cuprates, with nearest-neighbor hopping which depends on the occupation. Using exact diagonalization in a 4 β€’ 4 cluster, we obtain a large enhancement of d-wave pairing correlation functions for optimum doping. The physical picture is co
