Engines and humans play so completely different chess that even if you get a variation where you perform relatively well against engines they might be useless against humans.
I tried this back in Rebel Decade times, because I could beat the engine at Depth 6. So what I did was using the same openings and moves I was using to defeat Rebel Depth 6 against humans. The result was that I performed worse against humans than with my usual repertoire, because humans played nothing like Rebel, and they wouldn't play the blunders that were allowing me to beat Rebel, so it was useless.
That does not mean that the humans are better than Rebel that was dumped to depth 6 ....
It's just that the humans compared to Rebel were playing at a higher depth relatively speaking .....

The second game where the "Busted Italian" lines were put to the test at correspondence time controls just finished:
The Busted Italian II
[pgn][White "Master Om"]
[Black "Uly"]
1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. d3 Bc5 5. O-O d6 6. c3
O-O 7. Bg5 Bb6 8. Nbd2 h6 9. Bh4 g5 10. Bg3 Nh7 11. a4 a6
12. Bb3 h5 13. h4 g4 14. Ne1 Ba7 15. Nc4 Be6 16. Nc2 Qf6
17. a5 Ne7 18. Qe1 [/pgn]
While black has thus failed to reach any line with an edge, white hasn't been able to get an eval above 0.00 either.
7...Bb6 is an interesting move in that it was mentioned by Hikaru Nakamura in one of his videos (he calls it the best move, so these lines are known by elite players. As a human I really don't understand why Bc5-Bb6-Ba7 is so good... why not just Ba7? Why can't white take advantage of the lost tempi?)
The third game is underway and I really hope white can get an edge and refute these defenses, because I already played the best black had and couldn't flip the tables, the only interesting thing remaining is to see black's defenses being cracked.
FWIW, both Cfish-dev and Lc0 (Network 384x30-t60-4300) suggest 15. d4 rather than Nc4.

15.d4 is 0.00 (like 15.Nc4 but it took my opponent more than 11 days of analysis to see that 15.Nc4 is 0.00), anybody thinking otherwise is welcome to jump in
I wonder how long would an unassisted engine need to see this correct score...

Wrong. It took 11 days to find d4 and all sub variations is 0.00 so i opted for non main line move Nc4 and delayed d4 with suitable preparation.

NO. I have about more than 20 games ICCF and 5 games of AICCF. Hence not able to get cpu time to analyse and play. Will play in a day.

That's fine, take as much time as you need, that's why we don't have clocks. I was just friendly teasing
