[Retros] solving retros in RIFACE : call for problems

[CAILLAUD Michel]

Hello,

The annual french meeting will take place in Ecully (not
Saint-Germain-au-Mont-d'Or for technical reasons), also near Lyon, from
18th to 21st May.
A "classic" solving event, part of the Soving World Cup, as well as a retro
solving competition will be organized.
I am in charge of retro solvinig this year and need some originals.
There must be some easy ones for (almost) everybody to solve and others of
"reasonable" difficulty (not too difficult, considering the limited solving
time).
The PGs should be C+ and the non PGs should allow clear distribution of
points.
Problems will compete in the retro section of Phénix 2018.
Be careful to send submissions to my e-mail address and not by answering
this mail!

Best Wishes,
Michel
