The problem with a positional testsuite is often that it's hard to verify the correctness of the answers. The positions below are from recent books about positional chessplay. They come out of analysis by Grandmasters, and, as far as I could verify, are checked with computers. Still - no guarantees they are all correct. But this should be fun nonetheless. The full analysis is not includede because of copyright reasons, but I've very briefly indicated the main idea behind each move. Feel free to indicate your results.
