Jaroslav Stun passed away… With a deep condolences to family and friends
The worldwide viral pandemic turned out to be much stronger than my plans for the regular release of
ANDA FAIRY PLANET and the publication of results from the international DANKA PETKOVA 100 MT,
which aroused great interest – I received over 60 originals from world-famous masters! … (Petko A. Petkov)

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”.
…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/
(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.
I got to know Günther in the 1990s during one of the chess meetings in the German town of Andernach. We continued to see each other there every year but only had little contact in between. This clearly changed in 2002 after Günther had read my article “Beckmesser versus Stolzing”, which was published in feenschach,144/ 2001, and dealt with reflections on the legality under the condition AntiCirce. Günther’s interest was not only aroused by the chess-related retro analytical content of my piece but also by the parallels I had drawn to the art term of Richard Wagner’s opera “Die Meistersinger von Nürnberg”.
We entered into a vivid exchange of ideas via regular mail and e-mail which, over the years, has amounted to several hundred pages. Our preferred topic, for obvious reasons, was problem chess with a focus on retro analysis, but we also discussed about classical music, in particular about Richard Wagner’s oeuvre. I always wholeheartedly enjoyed Günther’s critical reviews of symphonic concerts and opera performances, which were coined by profound expertise and a good sense of humor. His observations would have outshone the newspaper comments of many renowned cultural journalists.
The great German retro expert Wolfgang Dittmann (1933-2014) was the first one to pick up my appeal in the above-mentioned feenschach-article to give fresh life to the almost forgotten defensive retractor by connecting it with the condition AntiCirce, closely followed by Günther Weeth. Günther brought new, creative ideas to the table, which did not only concentrate on theoretical innovations but also elaborated on the riddle character, on the degree of difficulty, and on surprising effects. Some of his ideas proved to be real “gold veins” and opened new perspectives. All in all, Günther’s life work in this genre consists of approximately 250 problems.
In the course of our lively correspondence, I soon realized that we were kindred spirits whenever we worked on retro problems. The result of our almost magical connection comprises 80 joint compositions, among them numerous prize winners in notable international tournaments. This close chess co-operation led us to an even closer friendship, which also included our spouses, Gudrun and Doris.
As a former enthusiastic educator, Günther was not satisfied to merely compose and solve retro problems. Instead, he strove for explaining the secrets of fairy conditions and fairy pieces on the chess board to a broader audience in order to make the subject more transparent. A rich number of specialized articles in international chess publications such as feenschach, Die Schwalbe, StrateGems or Julia’s Fairies give evidence of his tremendous efforts in this respect. Günther was famous for his entertaining presentations at Andernach- and Schwalbe-meetings, which showed him as an eloquent and amusing protagonist of the AntiCirce defensive retractor.
The installation of the Magic Square in defensive retractors with the condition AntiCirce (see Weeth, “Die Schwalbe”, 240/2009, pp. 305-306) is a solid example of his intellectual joy to experiment. On the occasion of Günther Weeth’s 75th birthday in 2010, feenschach announced its 63rd Theme Tourney, where problems dealing with the Magic Square had to be composed. The rules of Günther´s creation “Magic Wander Unit” were explained by him and Hans Gruber in a complex “Convention” published in feenschach, 213/2015, pp.181-182.
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.

What happens in our Going Forward to Light and Order project? While I haven’t followed the project for about 3 weeks, the team was continuously discovering new highlights and new questions as well. Tonight I couldn’t provide any summary of the current situation, but let me show you some moments jumped into my eyes. Later on the members of the team might comment something more, and of course, all of us would appreciate your comments (and joining to the team as well! 🙂 )
Shankar always makes some nice graphical presentations for us. So, I’d like to share something with you:
“I did a small analysis of the way Leapers evolve into Riders, Hoppers and other related types. This scheme generates 116 different pieces – some of them possibly not yet used and/or named!
Note: the 116 pieces are generated from only the 3 basic leapers: Wazir, Fers and Wazir+Fers(Erlking). Another 63 can be added with the Knight evolving into Nightrider/Rose, N-Hopper, Nao, N-Lion, etc. Adding up to 179 Pieces!”
This is only a “simplest” part of Vlaicu‘s comment given to the scheme:
“1. I have some difficulties in understanding how a (1,2) Hopper can turn direction with 45 or 135 degrees. Maybe not all these angles are possible with all the leapers?
2. For the sake of clarity, I think we should divide the leapers into two categories: those with linear march and those with non-linear march.
The non-linear march can be further divided into Double Riders (e.g. Boy-scout, Girl-scout, Quintessence and the 4 types of ZigZag NightRiders recognized by Popeye) or Octogonal Riders (Rose)
3. There are also the double Hoppers – pieces which jump over two pieces – again with linear march and non-linear march (Double Grasshopper).
4. There are also the newly invented movable hurdles – the Bul and Dob pieces, which are similar with the “hurdle colour changers”. So far nobody decided to use an Andernach Bul Grasshopper, but I think that combination should be also possible…”
The ending phrase by Maryan Kerhual on the Homogeneity topic made me smile:
“First remark: do we agree that the chapter Pieces should only answer to the question “how are pieces allowed to perform a move geographically on a normal chessboard”? (the question, is the piece allowed to move is not pertinent). If the answer is yes, the classification of the Jaguar in 2.2.5 of the Fairy Glossary, and of the Bul Grasshopper in 2.3.4 of FG is questionable.
Second remark: do we agree that Leapers are pieces that are not blocked by obstacles on their way to a given square, whereas Riders need encountering no obstacles on their way.
In that case Maos and Moas should be classified as Simple Riders (see 2.2.1 of the) and not as Restricted Leapers (see 2.1.3 of FG), an option already admitted in FG.
By the way the Nightrider should have been called Knightrider to be consistent with a unified terminology, but we are not going to modify that poetic name!”
And the same Maryan about the Attributes: “We know about that excellent idea of associating attributes to some pieces, very efficiently in the case of Royal units, Neutral and Half-neutral units , Undefined Pieces, Invisible Pieces, excellent because these characteristics cannot be confounded with conditions.
But the idea could also be applied to conditions, and I see two interesting attributes associated to conditions to begin with: 1) attribute ‘ultra’ ; 2) attribute ‘strict’…. “
Of course, the discussion goes in different directions, and can go continuously deeper and deeper, as Vlaicu commented:
Human imagination has actually no limits! 🙂
“What we need to do immediately is make a selection of some popular elements belonging to each of the main groups and fill out the intended details like history, popularity, supporting software and example problems to put into a publicly viewable and searchable database on JF. This will give some immediate benefit and feedback. We can then fine tune our work to improve it further.” (Shankar)
Thanks a lot to everybody involved!

Coming soon: nobody in the waiting list…
- (30.11) No.1564 (hs#4) János Csák (Hungary) & Aleksey Oganesjan (Russia). Attractive sacrifices lead to ODT “model checks” and model mates.
- (28.11) No.1563 (h#4 ; Grasshopper) Niels Danstrup (Denmark). An interesting coincidence about the numbers: the previous problem by Niels was No.1553 on the date 28.10!
- (26.11) No.1562 (h#4 ; Functionary Chess) Oleg Paradzinskij (Ukraine). Warm welcome to Oleg!
- (24.11) No.1561 (h#2 ; HurdleColourChanging pieces, Lion, Rook-Lion, Rose-Lion) Michal Dragoun (Czech Republic). The problem is not computer-tested – I found firstly geometrical pattern and then I discovered, that neither Popeye nor WinChloe are able to test Andernach roselion…(Author). Important to note two different names for the same property: Andernach hoppers = HurdleColourChanging pieces.

Our chess problem field is not gaining as many new followers as it should. There is a competition for ways to spend leisure time: various other board and video games – most of them available online, as well as the old ways like music, movies, serials, sports – again mostly online. Also, the regular game is experiencing a boom, with more OTB and online tournaments. But here too, players are less interested in chess problems, than before.
In this atmosphere, we should try to make our hobby as attractive as possible for newcomers. The biggest area in chess problems is the category of fairy chess. Here, more and more new forms are being invented. The easy availability of chess problem solving software is probably helping in this. But this has created a big obstacle for the newcomer, who might well be scared away by the plethora of incomprehensible terms under the diagrams!
Therefore, this project is an attempt to provide an easy and helpful way for a newcomer to find the definition of an unfamiliar fairy element, as well as some additional information about its history, popularity, software supporting this element and of course, some carefully selected example problems which bring out the characteristics of the element.
In the process of this project, we need to classify the various elements into groups and sub-groups, along with linkages between similar elements – in short, produce a taxonomy or knowledge organisation of fairy chess elements. This will aid understanding, meet the human need for orderliness, and help to check whether a particular element is already existing.
Of course, various sources are available online, many of which meet the above objectives. These have been used as the basis or foundation for this project. All of them have been listed and acknowledged. However, all of them have some shortcomings in terms of completeness, being up-to-date, clarity, example problems and organisation. Our project is an attempt to address all these shortcomings.
We welcome all comments and suggestions!
A great work to classify fairy elements has been already done mostly by Shankar Ram and Chris Tylor! (Julia)
