[Retros] RIFACE: Retro composing tourney

[Alain BROBECKER]

(try to separated links, don't know why they got together)
Dear retro friends,
You can find the tourney announcement here:

http://abrobecker.free.fr/ThemeRetroRiface2021.pdf
http://www.phenix-echecs.fr/Messigny/AFCE.php
and hopefully some other places...

Compose a retrograde analysis problem (a C+ proof game or a classical retro) with the "advantage game" condition:
one side has given a piece before the game. Castling with a ghost rook is not allowed in proof games (because not C+).

No other fairy condition, no Illegal Clusters or Retractors. Only one problem per external composer
(send to retro.riface2021 at gmail.com before sunday 11/07 at 15:00 (UTC+2)).
Please send if possible a diagram with stipulation, the Forsyth notation of the position as well as a detailed solution.

You have two example proof games and hints on how to make computer tests in the pdf file.

Happy composing,
Alain
