  We study local diffusion rate $D$ in Chirikov standard map near the critical
golden curve. Numerical simulations confirm the predicted exponent $\alpha=5$
for the power law decay of $D$ as approaching the golden curve via principal
resonances with period $q_n$ ($D \sim 1/q^{\alpha}_n$). The universal
self-similar structure of diffusion between principal resonances is
demonstrated and it is shown that resonances of other type play also an
important role.
