Entries on diagrams must be sent by 30th of October, 2017, to director of tourney Borisas Gelpernas, Vytenio g. 27-15, LT-03112 Vilnius, Lithuania or by e-mail: Borisas2011@gmail.com. Write your post address.

Dear authors, and readers, coming back to the next fairy tournament, JF-2017/II, I’m very sorry to announce that I need to postpone it again due to all other obligations I have. So, next informal fairy tournament on JF will start on October, 1st, 2017 and end on March, 31st, 2018. I’ll announce the judge during September.
New problems for Retro&PG 2017-18 will be published regularly again starting September. No breaks in publishing fairy announcements on JF upon request.
In 2018, I plan to have a break between informal fairy tournaments again, and the next tournament is planned from July, 1st to December, 31st, 2018, closing the year and WCCI and FIDE Album cycles. Awards of JF’s tournaments, articles, announcements are welcome for the period of break in publishing original problems, April – June 2018.
The breaks are made for judging I need to finish as the last year of tries to combine it all showed me it doesn’t work, either my evenings are devoted to judging or to publications, and judging goes too slowly with all interruptions. – Julia.
The Award of JF-2015/I
“In total, I selected 40 problems, the most I have ever awarded in any tourney I judged. I consider myself a rather strict judge, but this time I had no difficulty finding problems to include in the award. My main difficulty was to leave out many other candidates that were also good and interesting. I can say that it was the strongest tourney I have ever judged. Congratulations for making this happen.” (The judge of JF-2015/I, Kostas Prentos)
Only the first and the longest informal competition on JF, April-December 2012, had more problems and authors than January-June 2015. In 2013-2014 we had six 4-months tourneys, and the 2015/I was the first 6-months tourney. At the end of that period, I felt guilty about giving so much work to Kostas Prentos as the judge. Now, he writes in the award, “neither of us expected such a large number of entries: 169 original compositions and versions, by 57 composers”.
Today, it is time for readers to enjoy the Award of JF-2015/I, appearing like a booklet of selected problems… The 23 pages of the award include not only detailed comments for 40 rewarded problems (the comment to the 1st Prize takes 1,5 pages!), but also some remarks for 44 problems left out of the award… What an appreciation for the work of all composers!
And the last, more technical detail: the award you see was fully prepared by Kostas, with all the diagrams and links to original publications, leaving me without work… and words to thank him!
My sincere congratulations to the authors of rewarded problems and gratitude for all the comments, always highly appreciated by the authors and judges.
The four week composing tourneys of the 60th WCCC have been announced as of 18 July 2017.

Dear authors, readers, the first fairy tournament of this year, JF-2017/I is just finished with 54 problems. I’m grateful to all participants, and wishing the judge, Tadashi Wakashima, to enjoy your works!
About the next fairy tournament, JF-2017/II, I need to tell you that I’m going to postpone the beginning of it till mid-August. I regret about it myself, but otherwise I can’t finish all my obligations, mostly about judging. With almost regular updates of two websites I really have no time for anything else, including the own composing too.
Of course, I’ll continue to update wfcc.ch, and will publish fairy announcements on JF upon request.
I’ll write about the next fairy tournament after WCCC in Dresden, 5-12.08. – Julia.

A couple of ,,Wenigsteiner” to enjoy for beginners and masters
Dedicated to Julia
I want to thank Julia for the friendly way, she handles all the problems, we bother her with. Though I do not know whether she is a “proca-fan”, I hope she likes one or the other.
The author presents a selection (PDF) of 15 Proca Retractors with Anticirce Cheylan condition, each using not more than 4 pieces on the board. Please, see the first page with diagrams only if you would like to try solving. The second page gives some hints, and the third page presents the solutions.
Published with the gratitude to Andreas! (Julia)
See the definitions of Proca Retractor and Anticirce Cheylan.
Defensive Retractor: In Defensive Retractors, White and Black retract (take back) a given number of moves (-n moves), in order to reach a position in which a forward stipulation (e.g. #1, s#1) is met. Given a choice, Black will retract those moves that avoid or delay White’s goal. Unless otherwise stated, Black may defend by mating White through a forward move, if such an opportunity exists after one of Black’s retractions.
The different kinds of Defensive Retractors only differ in the way uncaptures are handled, of course only legal uncaptures are allowed. In Proca Retractors the retracting side decides, if and what man was uncaptured.
Anti-Circe (Cheylan): After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). Captures on the rebirth square are not allowed. Game array squares are determined as in Circe: R, B & S go to the square of the same colour as the capture; Ps stay on the file of capture; fairy pieces go to the promotion square of the file of capture.
