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)

Controller: Michal Dragoun, m.dragoun@gmail.com

Judge: Juraj Lörinc

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.

https://yacpdb.org/#361876 has one phase (d) with an unused white piece, as does https://yacpdb.org/#373473 - (b).

I like this one the most:

Zidek, Alexander
Schach-Aktiv, 1989
1st Prize
(= 2+14 )

h#2
b) Remove d5
c) Cont Remove a4
d) Cont Remove d7
e) Cont Remove f7
f) Cont Remove f3
g) Cont Remove b6
h) Cont Remove b5

a) 1.Kd6 Qa3+ 2.Ke5 Qxe7# (MM)
b) 1.Kc5 Kd3 2.Kb4 Qc3#
c) 1.Kc7 Qa7+ 2.Kd8 Qb8# (MM)
d) 1.Kd7 Qa6 2.Ke8 Qc8# (MM)
e) 1.Kd5 Qa2+ 2.Ke4 Qe6#
f) 1.Kb7 Qh1+ 2.Ka6 Qxa8# (MM)
g) 1.Kb6 Qg1+ 2.Ka5 Qa7# (MM)
h) 1.Kb5 Qf1+ 2.Ka4 Qa6# (MM)

bK rosette, no repetitive moves.

@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 :-)
