Kondrachenko position

Grandmaster Eugene Kondrachenko from Homel, Belarus, is the best online player on internet, he won over 1,200 internet tournaments!!!
A couple years ago I asked him to spar with my student William Chinzewe from Zambia, they played a dozen phenomenal matches, that helped Willie win the African championship and several World Junior titles.

In this article grandmaster offers this position to analyze (White to move and win):

Black position is very overdeveloped, with no waiting moves and the stuck behind piece on a7.
Try to figure it out, then compare to the analyses in the following comments.

1.cd4 is the standard play in such position, exchange the central checker e5 to split the flanks.
