If it is a study, alternate winning moves don't mean the study is not good. It looks like a study to me, does Walter Eigenmann not say something about it? In the line with Bc1 Stockfish still often gives Bxh6 but later, not in the last output line from Harvey and a few before, for the beauty of the study (if it is one) it is best to play it directly so Black can't avoid it.


In positions with a large imbalance, Stockfish does use the classical eval, so I'm not sure this is a good test of a new net. I have not compared it but Blue Marlin (14.7) without NNUE also plays Bxh6. Blue Marlin needs a depth of 60 plies to rise above +1, so not surprising that a program like Rebel does not find a big score

Code: Select all

And at least 1.Rh3, that was crucial before, doesn't seem to work now anymore neither.
Have to investigate some further, e.g. with 1.Rh4, but you really coud have killed the dual.

I'll write an email to Walter regards
