Queen's gambit. Yanovsky system for black

I made a new work - The Queen's Gambit. Yanovsky system for Black.
After the moves 1.d4 d5 2.c4 e6 3.Kc3 there is a paradoxical, but strong and cunning move 3...a6! The purpose of which is to simply take on c4 and support the c4 pawn with the move b7-b5.
This system was first played by David Yanovsky in 1899 against Tinsley, Lee, and a little later Schlechter (1902), then it was played once more by Flor and Alekhine. But the option somehow did not take root among the elite of those years. The option has already begun to acquire new ideas. in the 21st century and since 2010, the option has been actively used by strong players.
I started playing this option actively in 2020 when I studied Grandelius’ analysis (The Queen’s Gambit according to Magnus Carlsen in English). Time passed and I began to understand that Niels’ analysis could be continued in some places or even changed, for example, one of the main lines: 1.d4 d5 2.c4 e6 3.Kc3 a6 4.cd ed 5.Kf3 here Niels recommended 5.. .h6 so that the bishop does not go to g5, but this move is somehow slow and after a long analysis I came to the conclusion that 5...c6 is stronger. Although in practice the move 5...h6 served me well for several years, I still decided to abandon it in the analysis. I also analyze if chess players play catalon, for example: 1.d4 d5 2.c4 e6 3.Nf3 here I also recommend playing 3...a6! Catalon is analyzed in very, very detail, sometimes I would say even excessively. But still, I strived for maximum fragmentation, so that it would be clear to everyone what to do. In my analyzes I gave very detailed lines, stuffed with new features not only for black, but also for strengthening the game for white. The goal of the work is to build an opening repertoire for Black against the Queen's Gambit. You can say that I am sharing with you all my developments that I have done since 2020. I have not hidden anything, everything is as it is.
In this system, you can not only count on equality, but also with an eye on winning with good playing technique. The work is also suitable for trainers who train their students. The work is generally intended for skilled players, but even dischargers will find benefit.
There is no text in the work, but each option is given an assessment of the situation.
Also, this work will be ideally combined with my other work: We play against 1.d4 Side variations. London, Colle, Zukertort, Jobava-Rapport system.
Thus, these works constitute a complete repertoire for blacks.
