Computers are bad in these kind of positions, as they will not consider to give
back a material plus to get rid of the pressure. I think there will be no
program that finds 7 ... d5!, even not after weeks of calculating!

I rely on my own analysis. As I said, computers are of no help in such
positions.

I disagree. After 7 ... d5 8. Bxd5 c6 9. Bb3 Be6 I think White is lost. There is
no compensation, the bishop on b3 is going to be exchanged and Black can simply
develop his pieces. F.e. Qd7 and 0-0-0, or N8e7 and Nf5 or Nd5.
