Using the fact that the electron ionic polarizability response time is practically instantaneous  we show that a charge carrier induces large attractive potential to a second carrier in small pockets in the two particle position space. Taking into account the inter-carrier repulsion and the kinetic energy needed in order to confine the carriers to the attractive potential pockets we find that the pairing energy is of the order of the energies seen in high Tc superconductors.
