Here is a call for compositions #2 and h#2.
The theme is free for #2.
The h#2 must be in the form "Helpmate of the Future" (HotF), which is defined as "h#2 having any number of solution pairs, where in each pair the solutions are closely related".
Examples of such problems you can find in the section A of this award: https://drive.google.com/file/d/0B2-Lv0IlDIs6N1lhWjNQckpMOWs/view
Fellow composers, please send!
