Theme: Fairy #3 – #8 with Dresden idea:
A strong defence by one black piece is eliminated, but another, yet weaker defence by a second black piece, newly brought into play, substitutes for it. Depending on how the strong defence is eliminated there are three main types of the Dresden theme.

Quick Composing TT-184 by SuperProblem
Tourney name: “Rebirth square paradox”
Stipulation: fairies
Theme: When rebirth of pieces applies in fairy conditions, an empty rebirth square usually means an advantage for the transported piece’s party, as it preserves the piece’s power. This tournament, however, is looking for the exceptions. It requires chess problems of any kind applying any fairy condition involving rebirth of pieces, where the vacation of a rebirth square of a piece belonging to the party which is going to fulfill the problem’s aim (e.g. white in n#/h#n or black in s#n/hs#n) means a disadvantage and/or the obstruction of such a square means an advantage for that party because of the potential rebirth (not) taking place.
All stipulations, fairy pieces and additional fairy conditions are allowed.
Judge: Klaus Wenda. Closing date: February 16, 2017

Black Retro „Duals“
by Günther Weeth, Stuttgart
Even after more than a century of the composition of retro problems we are confronted with a certain problem, strange as it might appear to most of us. It shows off when it comes to the evaluation of defensive retractors.
Some retro experts strictly representing no other style than the classical orthodox one, thus being exclusively committed with the aesthetic demands of help retro play sometimes seem to be mistaken when it comes to evaluate defensive retractors. Every now and then you may come across their verdict on black retro moves obviously being ambiguous… → see the whole article
