16th European Chess Solving Championship H# Composing Tourney Announcement The announcement is available here: https://soks.sk/wp-content/uploads/2023/01/ECSC_2023_TT_hm2_announcement.pdf
Helpmates in 2 moves are required with successive twins (at least 3 positions a), b), c), and possibly more) formed by removal of one piece of either colour from the preceding starting position – so called striptease theme.
E.g. if the problem has 5 positions, four of them are formed by gradual removals of one piece from previous position, starting from the diagram (see example P3).
Fairy pieces and fairy conditions are not allowed. Twinning types other than successive removal of pieces are not allowed. Each starting position should have only one solution, multi-solution positions are not allowed.
Maximum of three entries per person, joint entries count as full entries for all co-authors.
Closing date: 1 May 2023 (the award will be announced during the ECSC in June 2023 in Bratislava)

I kindly ask the administrator of the site to remove the intolerable post #5 by the person who already was warned by the WFCC Ethics Task Force for his behaviour in the MatPlus forum. |

В этих позициях есть не играющие белые фигуры. Это не рекорды. |

For an example of the victim getting her clothes on again - 27 phases, see P0539460, and the comment by Teppo Mänttä. Wrong diagram (must be 4R3/B2B4/3NR1q1/2N1p2p/4P1rn/3K1k1p/6p1/6r1), but correct changes and solutions. |

@Victoras: Согласен, очень хорошая задача. Выдающаяся в стиле стриптиза. Как и у Арпада Мольнара, но у него не тематическая в этом конкурсе. Они, кстати, в одном Альбоме ФИДЕ :-) |
