Award JF 2018/II (Kjell Widlert)

I believe, announcing an award is one of the most enjoyable jobs for any editor. And the one I’m glad to present to you is also so carefully made, including detailed analysis of problems and versions, written in a pleasant style of sharing opinions, and fully prepared for publication after all… not leaving any work for me (except writing these few words I couldn’t really find to express my delight and gratitude)!

Dear authors, readers, enjoy some wonderful reading for Easter holidays! My warmest congratulations to the winners! And my deepest appreciation to one of the JF’s most faithful contributors Kjell Widlert, the 2nd time overtaking this hard work – for me, for JF, and for all of you!

Well, I have to admit I’m very happy about my own results as well. For about 5 years of composing not more than 3-5 problems per year, when catching some time from other jobs, when getting some inspiration stronger than the guilt about all my waiting lists 🙂  And now, not only happy about the distinctions, but also appreciating Kjell’s comments very much, good words and wise observations by the high class judge and composer.

Sad news – Jaroslav Stun

Jaroslav Stun passed away… With a deep condolences to family and friends

Dear Jaroslav’s colleague and friend,

It is with deep sorrow and sense of loss in my heart when I write these lines.
However, as his colleague and friend, I wanted to let you know that my father has recently, shortly before his 70th birthday, passed away, after a valiant month-long struggle with a severe COVID-19 infection.

I know and I am sure Jaroslav valued every bit of exchange, collaboration and sense of community he took part in together with you on the field of Chess – all the Problems, Compositions, Fairies and Puzzles he worked on or shared with you; and I wanted to take this time to Thank you for all the joyful and happy moments you made for him.

My dad died in complete peace, we know the One who my father believed in and relied on the most throughout his whole life, took good care of him, and we will always keep Jaroslav in our hearts and memories.

Jaro Stun

Anticirce plus Circe in the defensive retractor

Click to read the article in PDF, 5 pages

Günther Weeth (1935-2020) himself had prepared this translation of his article published in Die Schwalbe 306-2/2020. p.821 ff. in November 2020 in German language. We have made some small adaptions replacing examples 5&9 with new versions as the Schwalbe-originals had turned out to be incorrect. However the original source of those versions is “Die Schwalbe 2020, version 2021”.
K.Wenda, A.Thoma

…So far my first explorations in the ”new territories”.
I hope I could draw the attention of retro-experts on the combination AntiCirce + Circe inspiring them to continue my studies.
Günther Weeth /Stuttgart, November 2020/


In memory of Günther Weeth

In memory of Günther Weeth

(13 August 1935 – 28 December 2020)

By Klaus Wenda (Vienna, Austria)

On 28 December 2020, Thomas Brand’s Retro-blog featured truly sad news: Günther Weeth had died after a long and severe disease.

Günther Weeth became a member of Die Schwalbe, the German association for Problem chess, in 1973 and earned his first spurs as a strong solver. Due to the friendship with retro specialist Josef Haas, his interest in retro analysis awoke. The traditional Christmas solving tourneys of the newspaper “Stuttgarter Zeitung”, widely known by an international problem solving audience, offered him the perfect arena to thrill, or sometimes exasperate, the participants with his witty and tricky riddles.

-> see more / less…

Since the summer of 2020, Günther intensively worked on a new project, the defensive retractor with the conditions AntiCirce+Circe. He presented the results of his analysis, decorated with some quite original problems, in an article in Die Schwalbe, 306-2/2020, pp. 821-824. Günther still translated the piece into English before his passing. It is expected to be published in Julia’s Fairies soon.

My sincere sympathies go to Günther’s family, especially to his wife Gudrun, who always appreciated his time-consuming hobby, problem chess. An eminent problemist left Caissa’s World – and I have lost a good friend.
