We compare the two most popular approaches to the problem of instanton-antiinstanton interaction at high energies - the valley method and the effective-Lagrangian approach - and use them to calculate the next-to-next-to-leading term in the expansion of ``holy grail'' function determining the cross section with baryon number violation in the Standard Model.
