A model is developed for the motion of an electron in a 2d-quantumantiferromagnet (QAFM). The Hamiltonian for the layer consists of two parts: The H,\_rHamiltonian for nearest neighbours and the 3-site term. From the layer we derive by ejection of a single extra hole an effective Hamiltonian. The i
