Composers' cooperations (3)

In this post we will see five problems created by cooperative composers. In general, the chess composition is a lonely activity. Most of the time it is you and your chessboard, or even your computer running the proper software. But often the composers share an idea with someone else and the composition has more than one parents.
Who has done most of the work? Finally, it does not matter. The cooperation is worthwhile.
Whose name will be written at the top? We said, it does not matter. The main thing here is that the composers cooperate and sometimes they become friends.
There are in the chess history rare cases, where composers having together awarded compositions, at the end they do not speak to each other.
