P.A.Petkov – Question about Tzuica -2017

Dear organizers of Tzuica-2017,
To which section ("A" or "B") belong problems composed only with orthodox figures (without other fairy conditions) but with "hyper- sets" of figures (for example: 3 black Rooks, 4 white Bishops, etc ( with legal positions according to the orthodox rules)?

Dear Petko,

We have been organizing the Tzuica Tourney with two sections since 2009, but this is the first time we have received this question.
The two sections (A: Orthodox and B: Fairy) are defined very simply: are considered "fairy" the helpselfmates that have at least one fairy condition or one fairy piece. The orthodox helpselfmates have no fairy condition or piece.

We opted for dividing them because more often than not, realizing a theme is easier when using a fairy condition or piece.
Up to now, we have not been confronted with orthodox problems with hyper-sets of pieces. As long as the position is legal, according to our definition these problems will be judged in the orthodox section.

Dear Eric!
Thank You very much for this answer! It expresses a very modern, contemporary interpretation of an important principle&term in the chess composition!
