I thought you were TotalNoob69 from Lichess

Very interesting!
Is the theme-based position evaluation heuristic (mobility, space, king safety, and other positional and tactical factors) the same as the one in the Lichess tools?

Yes! I 100% agree.
Great that he took the time to watch the video and provide feedback without being defensive.

Thanks!
I need to delve deeper into Monte Carlo to fully understand your point. So far, I have not found it helpful in developing my chess skills.

Matthias Wüllenweber, CEO of ChessBase, was kind and open enough to reply to my video.

Yes, 4...d6 is rarely played.

I never came across a correspondence game in my local Mega DB.
My chess tools:
- CB and Hiarcs as DB programs
- Mega DB with weekly CB updates
- Corr DB with monthly ICCF updates
- Hiarcs openings book
- SF and LcO
- Forward Chess
- Chessvision.ai
- Qchess.net
- Lichess
- Chessable

Correspondence players spend days analyzing a position with the strongest engines. You can still find interesting ideas as L’Ami showed in the NIC Yearbooks.
I only look at games post SF-NNUE and use the corr DB to see if there is consensus on the strongest move and any new ideas from top players.

23... Nf6 24. d6?
(24. Rg4+! Nxg4 25. Qxg4+ Kh8 26. Qd4+ f6 27. d6 Bxg3 28. Qd2 Rf7 and wins.)
24... Bxg3
(24... Qc8! with equality.)
25. Rg4+ Nxg4 26. Qxg4+ Kh8 27. Qd4+ f6 28. Qd2 Rf7 29. Bxf7 Kg7 30. Qd3 1-0
Aronian saw the idea but chose the wrong move order but won after all.

The knight came from g6.

33. Bf6! Bxf6 34. Qxf4 and mate is unavoidable.
