Julia, Luce is correct, as I clearly miscounted the number of Black moves. Please change the stipulation to ser-h-ep#56 and take the “57.” out of the solution.

Thank you very much for the test. I did not know this was possible, despite having installed Popeye.

Dear Julia,
When I say 56, it is 56 not 57 because I register all the problems of Julia’s Fairies in winchloe format ! 🙂

Can be extended to 58 moves with an extra black pawn on a6.
