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 -------------- next part -------------- An HTML attachment was scrubbed...
