"Die Rose ist vielleicht die schwierigste Märchenfigur.???" (WoW)
Hier ermöglicht sie nette Echomatts.
Die Aufgabe scheint ein Überbleibsel des Länderkampfes Schweiz-Schweden zu sein, wo in der Märchenabteilung hs# mit Rosen/Nachtreiter gefordert waren. Leider ist die weiße Rose etwas schwach eingesetzt. Ebenso die wLL, die nur Fluchtfelder des sK decken. 5L/5P

Informalturnier 1986 Rest, Preisrichter Gerhard E. Schoen, Preisbericht f-94 S. 252
Eine unscheinbare Stellung mit erstklassisch tückischem Lösungsverlauf, der eine SLTTD-Umwandlung mit Idealmatt als Thema zeigt. Vergleicht man dieses Problem mit ähnlichen aus der Glanzzeit dieses Genres, den frühen siebziger Jahren, dann erkennt man erst diese Leichtigleit der ausgefeilten Darstellung, ohne dabei Komplexität und Lösungsschwierigkeit zu vermissen (G.E.Schoen).

Die dreifache konsekutive Umwandlung im Serienzugpatt ist alles andere als einfach darzustellen. Nr.38 stellt bis heute das einzige Beispiel dar, das ohne weiteres Märchenelement (neben der Figur, in die umgewandelt wird) auskommt: Kompliment.

Auf die Spitze getriebener Task (die im Anhang gedruckten Zwischenstufen mit 5-7 Umwandlungen bringen nichts Neues, sondern sind eher Konstruktionsskizzen auf dem Weg zur Achtfachsetzung). Die verwendeten Motive sind immer die gleichen (und dadurch, dass eine Geschichte öfter erzält wird, wird sie nicht unbedingt besser); die Bedingung "`Cavalier Majeur"' ist ein Taschenspielertrick, um den Ärger mit der lästigen Springerumwandlung zu vermeiden. Die achtfache Synchronumwandlung mit nur 12 Steinen ist aber dennoch sehenswert (Richter HG)

In der Lösung bezeichnet 'PH' das projektive Feld in horizontaler Richtung; 'PV' das projektive Feld in vertikaler Richtung; 'PD1' ist das projektive Feld in Richtung der Diagonale a1-h8; 'PD2' ist das projektive Feld in Richtung der Diagonale a8-h1.

A.Buchanan: Together with excellent paradoxical key, and the 4 clean mating lines, a large number of potential cooks are prevented quite economically (see non-solutions, above). wBf6 in particular has many roles. So on this occasion a minor dual at one point later in the solution seems completely acceptable. A very original composition!
Interessanterweise werden in der Lösung alle vier unendlich entfernten Felder des projektiven Schachbretts benutzt.
A.Buchanan: In projective geometry, every family of parallel straight lines intersects at an infinitely distant point. Chess problem composers in the former Yugoslavia have adapted this idea for the chessboard, adding four special squares “at infinity.”

Now a queen on a bare board, for example, can zoom off to the west (or east) and reach a square “at infinity” from which she attacks every rank on the board simultaneously from both directions. She might also zoom to the north (or south) to reach a different square at infinity; from this one she attacks every file simultaneously, again from both directions. Finally she can zoom to the northwest or southeast and attack all the diagonals parallel to a8-h1, or zoom to the northeast or southwest and attack all the diagonals parallel to a1-h8. These four “infinity squares,” plus the regular board, make up the field of play. (2015-11-20)
Henrik Juel: Fine explanation, Andrew, but I still need to see the intended solution (if you know it); this may also clarify the weird stipulation (2015-11-20)
Alfred Pfeiffer: Diese Schachvariante wurde 1952 von Prof. Lav Rajcic und Nenad Petrovic erfunden (D.B.Pritchard: The Encyclopedia of Chess Variants) (2015-11-20)
A.Buchanan: The articulate explanation is not mine: I found it at http://www.futilitycloset.com/?s=chess
I think one needs to add that only line pieces have the privilege to leave the regular board in this way. Which suggests another variant with Nightriders. Now there are another 4 squares accessible only by Nightriders. (2015-11-21)
Henrik Juel: Thanks, Andrew and Alfred
Nice key, but too bad about the trial after 1... Kg3 (2015-11-21)
Henrik Juel: Andrew has pointed out that the flaw after 1... Kg3 is only a dual (2015-11-22)
A.Buchanan: Someone asks me: is there a cook? 1. D-PD2 Sc7a8,Sc7d5 can be answered by 2. Kh3# (2020-11-10)
A.Buchanan: By the way: the squares at infinity are on a straight line, but that cannot be navigated by the queen. For suppose the contrary: then the direction of movement along that line would have to be parallel to some direction of movement of the queen, i.e. by symmetry parallel to *all* directions of movement of a queen, i.e. since lines parallel to one line are parallel to one another, we conclude that all lines on the board are parallel to one another. This is absurd, so the queen cannot navigate the line at infinity (2020-11-10)

Added 1 Dummy to P1359493, and changed the dedicatee. My luck with this little series continues to hold: the dedicatee's surname begins with a D!

Arnold Beine: There is no need for checking 2.b8=Q!??, because Q-promotions are not allowed in Grashopper Chess. (2020-10-23)
A.Buchanan: Thanks so now we’ve found an explanation of why it is defined to be grasshopper chess! A lot of time and effort can be saved in chess composition if the default format is “no-cook chess” - a fairy format in which all unintended solutions and defences are by definition illegal! :) (2020-10-24)

Either the current position is a starting position, or White has just played 0. ... b1-b2, from a position with an impossible check which must therefore have been the starting position itself. In either case, none of the Black pawns have ever moved, and so are eligible to make a double move. wPc1 has also never moved. But what of wPb2? We are up in the air as to whether b2-b4 is legal.

Since we can never prove that a position is not a starting position, the default convention is that it is *not* the starting position. Therefore, White has just begun the game with Black in check, and played 0. ... b1-b2, so is not able to play b2-b4 later.

Eventually, when Chess960 becomes played out, we will all be playing Chess4E71, so best to learn it now. There are three diagonals wPb2 may move along, but only one of them works. Rigorous retro reasoning allows all the pawns to make a double move *except* for wPb2. (Author)
Henrik Juel: No comment (2020-08-30)

https://chess.stackexchange.com/a/29992/15543
A.Buchanan: Hi James, couple of nits about old Bosma:
(1) From the 1985 Laws: "Article 5. THE MOVES OF THE PIECES The King (a) Except when cast[l]ing, the king moves to any adjoining square that is not attacked by an opponent's piece." This is separate from Article 9. CHECK 9.1 "The king is In check when the square it occupies is attacked by one or two of the opponent's pieces; in this case the latter is or are said to be "checking the king.' 9.2 Check must be parried by the [move] immediately following." This point may have been an assumption in earlier compositions, as e.g. it prevents kings from being adjacent.
(2) And again from Article 5. "(f) Castling is prevented for the time being - (i) if the king's original square or the square which the king must cross over or that which it is to occupy is attacked by an opponent's piece," Does this prevent your 1.0-0?
What do you think? (2020-11-08)
James Malcom: Ah, why did I but never bother to look at the castling rules!

Well I see nothing against adjacent kings, and seeing about how the "loophole" was about was not explicitly stated couldn't be done, I see it as allowed, and thus what to watch out for in cooks.

The rule on castling says "piece," not pieces. So, quite simply, castling in, out (P1381498), and through (P1381499) check is allowed in my view. (2020-11-09)
James Malcom: Furthermore, if a king is "attacked," they are in check, plain and simple. So, since a triple check/ attack is not defined as a danger to the king, the king may go to any such square, including the acts of catling and adjacent kings.

Also, going by the law itself, and not the Bosma conditions, the king may be captured, but it does nothing and that side can never be checkmated, while Bosma Chess itself allows no king capture. But since the effect is the same, allowing for my jokes to be C+ by Winchloe if the program agrees. Maybe try out my castlings in it? (2020-11-09)
James Malcom: And indeed Andrew has tested my castling problems now-all are C+? (2020-11-14)
James Malcom: Typo-!, not ?. (2020-11-14)

The intended solution is beautiful and ambitious - I suspect it must have been cooked before the prizes were awarded, otherwise to me it would be prize material. (2020-11-14)
A.Buchanan: Alternatively, shifting wD to b8 and wTg6 to g4 fixes everything, at the cost of a flight-taking key. On the other hand in Bosma every piece comes with a downside, and Black can use wTg6 as a defence, always threatening e6-e5 when bK has shifted to d6. This to some extent compensates for the crudeness of the key. This is an amazing problem and if it has been sound at the time, I would have given it first prize (2020-11-15)
