[Retros] Solving in Messigny 2006 : problems

[Thierry LE GLEUHER]

Dear retro friends,

 

Here are the problems of the Messigny 2006 Retro solving contest (=French
championship).

All problems are originals for Phénix.

The solving time was 2 hours an half for the 10 problems (10 points per
problem).

You can try to solve them as quickly as Michel CAILLAUD, who was the winner
in 1h32’ with 100%.

Solutions and results in any days
