  We propose that the superconductivity recently observed in
Nd$_{0.8}$Sr$_{0.2}$NiO$_2$ with critical temperature in the range $9$ K to
$15$ K results from the same charge carriers and the same mechanism that we
have proposed give rise to superconductivity in both hole-doped and
electron-doped cuprates: pairing of hole carriers in oxygen $p\pi$ orbitals,
driven by a correlated hopping term in the effective Hamiltonian that lowers
the kinetic energy, as described by the theory of hole superconductivity. We
predict a large increase in $T_c$ with compressive epitaxial strain.
