Thx for tips. I just saw there are some courses on chess.com, that will be nice to compare claude understanding with Silman commentary as the gold standard.

Edit: I am pushing a small attempt on this position. I fed this one as a screenshot https://www.chess.com/lessons/roots-of-positional-understand... . I forgot to tell that it was black to move but that was fine. The analysis quality seems ok. What puzzles me is that it recognized the Carlsbad structure and talked a bit the plans around the minority attack, not only the correct explanations on g6 and why it should be played. This is where we benefit from positional stuff in the training data.
