Hello,
 
Here are the retros submitted to 19 solvers in the retro solving  
competition (French Retro Solving Championship) in Messigny last week-end  :

VI

1B4Br/pp3P1p/qpP4R/1Q1Pp1P1/1S1P2p1/4P1k1/2P3P1/4K2R
 
Add a piece on a5 and mate in 2  (15+9+1?)  (3 points per  solution; number 
of solutions is not indicated)
 

 
VII

RB1Sk3/RPp2pp1/K1p1p3/p1P5/4p3/1P6/P1PP1P2/2q5
 
Shortest path by wSd8?  (12+9)  (10 points)

 
 
VIII

1qk1K1SQ/pprpprpR/2p2p1p/7P/8/2P5/1P1PPPP1/1SB2B2
 
Minimal number of moves since first move by wTh7?  (14+12)   (10 points)

 
All problems are originals for Phenix.
VI is given here in an amended version, as the version submitted in  
Messigny was unfortunately incorrect.
Some points were given for incomplete solutions in VII and VIII with  
additional questions such as "which captures are determined?" in VII or "who is  
to move?" in VIII...
Before the competition, I thought this could be a tough set. Anyway, the  
new French Champion Thierry LE GLEUHER succeeded to solve everything in the  
given time of 2 hours, losing only 1 point due to a slight mistake!
 
Best,
 Michel
