Well, now this conversation is moot because Peter reported that it is a bug in Der Bringer (Thanks Peter!). Anyway, I meant uninteresting for a tactical/combinatorial test. I do not think it is a good idea to include a test where the key move is just a "natural" simple move that most of the engines will pick up even if they do not see what's going on. I would not be testing "combinatorial vision" in that case. I am going to include this position again...
