Hi Miguel, Six of us made lots of DP problems recently! They are mostly short HDP problems (i.e. Help DP, analogous to helpmate or helpstalemate). Would be really great if you can test some of them to make sure they have a unique solution and of the intended length? I've invited you to a thread within the usual Chess Studies & Compositions Server. There is a pinned post with about 50 new compositions in. Thanks, Andrew
