Georgi Orlov wrote a book on the Tango.

Hello,

    It sure seem the right place to discuss the black knight's tango opening. Maybe the reputation is bad on account of the following :

I just want to make sure I have not miss something decadent as my base dates from 2005. If, by chance there would be top games, I am waiting to see them. Comments are welcome.

Anyhow, after : 1.d4 Nf6 2.c4 Nc6 3.Nc3 e5 4.d5 Ne7 5.e4 Ng6 6.Be3 (a natural move) Bb4 7.f3 black has two options :

a) 7....Bxc3+ working on the doubled pawns or
b) 7....d6 followed by ...Nd7 and ...Bc5 working on the dark squares.

Can we say we have (up to move seven by white) a main line?

Since it looks so natural and strong I would like anyone sharing an improve version against the Tango. So odd, only one line against it?
And even if it is good, I like to have options.
