Very interesting initial position with black pieces only, which transforms into white during the solutions, Forsberg twins. It is nice example for Section B of the Alaikov 80 MT 2013 see announcement on http://kobulchess.com/en/tournaments/announcements/80-venelinalaikov.html (Diyan Kostadinov)

Ceriani-Frolkin QSss, Phoenix-Pronkin qb. Quickly after publication of problem n.24, I found a cook: 12. g7:g1R! 13.h2-h3 Rg1-g2 14.Rf3:g2 Sh2 15.R1:h2. Here is the attempt of correction (Author). I really hope that this excellent problem is sound now. (Diyan Kostadinov)

Problems 39 and 41 are partially tested only, so the solvers may enjoy to look them more deep.

In No.36 bRe4 guards 1 square in one phase but it's only a cookstopper in the other. Could it be improved or would be better some twinning which makes bR participate in the mate in both phases?

Hello Nikola and wellcome in KoBulChess comments! Yes, you are right that in problem n.36 in one phase bRe4 is just cookstopper and this is weakness, but we still can not find the improvement for that. The best will be if it is possible pawns only position, but is it possible? Will be very nice.

A rough scheme with bR and a twin:
White Pg7 Kf5
Black Re8 Ph6 Pd5 Kh5 Pg4 Ph4 Pb3 Pc3 Pd2
Twin Move d5 e4

Thank you Nikola for your nice version of n.36! Yes, with twin form some weaknesses are possible to be avoided.
