You end up with >something with a little less direction to it. I understand it. I meant to say that even a main line is not the interesting information that I want to see but it is the information that all programs give after solving the fail high. The problem is that even after you solve the fail high and have the main line I believe that the interesting information is the lines that your program considered for a long time. If programs can give a tree with the idea that I suggest that it may help people to understand the reason for the move. I suggested the lines that were considered for more than a minute but a better idea is to post first lines that your program considered for more time. I mean something like 1.Bxg7 20 hours 1.Bxg7 Kxg7 2.Ne5 15 hours 1.Bxg7 Kxg7 2.Ne5 Rfd8 3.Qg4+ 6 hours 1.Bxg7 Rfd8 Rxd8+ 3 hours If you can change your program to give this information that it will be interesting to see it. > >I had to stop the test because round 1 of the CCT was starting.
