A trial function is presented for the $H_2$ molecule which provides the most
accurate (the lowest) Bohr-Oppenheimer ground state energy among few-parametric
trial functions (with $\leq 14$ parameters). It includes the electronic
correlation term in the form $\sim \exp{(\gamma r_{12})}$ where $\gamma$ is a
variational parameter.
