Hi Alain,

I have taken all the diagrams that you hovered up, and am about to load them
in my website at www.geocities.com/anselan/chess.html.

A few questions:
(1) Is Type Z the official name?
(2) Who are the authors of all these?
(3) Why is No.4 Traits aux noirs?

Any other thoughts and comments are welcome.

Best regards,
Andrew Buchanan.

On a similar topic, i converted to FEN all the last move economy
records in coloring problem form (Type Z? ;), published in
Rex Multiplex 27 by Andrei Frolkine & Andrei Kornilow.
It was referenced as type C problem. The last entry in this .CSV
list are the problems' number in the magazine.

Also type D are interesting too in my opinion.
