Based on my understanding increasing the chess knowledge in Rebel is not going to help it to understand these positions. I understood that Rebel does the full evaluation at every node except the leaves so I guess that if it can see something important in the tree before the leaves then it is going to see it also in the leaves. Cases when something important is generated only in the leaves can be detected with less chess knowledge (maybe even faster) thanks to deeper search. In order to change my mind I need to see a case when knowledge does not help to detect the problem one or 2 plies earlier but help to detect the problem 10 plies earlier. If Rebel with full knowledge say +1 for white at plies 5-10 when default Rebel say evaluations near +1 for black at plies 5-15 then it is going to be a convincing evidence that knowledge in Rebel is what you think about when you use that word.
