Thank you for posting these solutions. Here are my remarks. The first
six solutions are of course correct.

This solution is also correct, except for the fact that the bBf8 could have
been captured by a wR or the wQ.
The original stipulation for this problem is : 5 last captures ?

The overall solution is correct, but only the last 4 pawn moves are completely
determined. Instead of c5xRb6 is it also possible to uncapture a bQ, the bR being
uncaptured after that, and then replaces the Q at b3 which gets unpromoted.
The original stipulation for this problem is : 4 last pawn moves ?

The solvers all considered that these problems where difficult, even the short proof
games, the easiest being probably number 3. Most of the solvers didn't have time to
solve more than 2 or 3 problems. The winner, Michel Caillaud, solved all the problems
but made a mistake in problem number 2.

I want to thank again all the composers that have send originals for this solving
