Of course but this was never a question here. These positions are wonderful! And big fun to test. Our sole topic was if these tests could have any meaning for programmers and the answer is no. Not because all here are so dick headed. It's because the results dont help. Test critics say that the so calle Elo numbers are really looking good. But they are meaningless for tournament practice.
