James Malcom: The first Valladao AP? (2020-10-03)
A.Buchanan: Hi James, there are 6 earlier ones in PDB, not counting those which are not marked as Valladao (could quite a few, as basic AP is 2/3 of Valladao). Type k='a p' and not g='fairies' and k='valladao', and set sort order by date. The ur-problem is P0003417. (2020-10-03)

Rosalie Fay: 1 ... f5 doesn't parry the threat. 1 ... fxg6 2 c8=B/Sf8 both work, so this line is dualistic. So no Pickaninny and no AUW. (2020-09-26)
A.Buchanan: I've been meaning to ask about threats, and here's a good chance. They are a cool shorthand for many solutions, and some folks have invented themes about them. But (as here) they destroy the logic of many problems where Black has a limited choice of moves, so we shouldn't apply them robotically, imho.
One obvious case is that in a problem where *every* Black move counters the threat, the threat is meaningless. Another obvious case is if it only counters one Black move, then it's kind of lame and again meaningless as shorthand. So unless there is an artificial theme declared with the solution, a threat should not be given unless it works against at least two Black moves.
Here every Black play except for 1... f5 defeats the "threat". Even 1... Kc5 which leads to the short solution 2. Le7# also refutes 2. c8=S. There *is* a theme AUW/Pickaninny, but the symmetric expression of this threatless theme is actually damaged by including a threat in the solution. (2020-09-27)
A.Buchanan: According to the Codex, a directmate or selfmate is unsound if it is cooked [i.e. has a solution that differs in its first move from the author’s solution] or has a short solution or no solution. The gravity of defects such as unintended duals, or unintended multiple refutations of [intended] tries is a matter for a tourney judge.
One issue with PDB is that we do not have a "sound/unsound" field, nor even a keyword for this! But even a brutally dualized problem can never be classified as cooked, and this one is only mildly dualized. (2020-09-27)
A.Buchanan: I am not trying to be "kind to duals" here. They are defects, and I applaud Henrik's analysis of them. Since we are not running a tourney, could we imagine some formula based on the graph structure of the solution which will automatically give us a figure. E.g. dual-less = 0, any dual in 2nd move is twice as bad as a dual in 3rd move, etc? The length & breadth of the problem would has to be a factor. Can we construct an ideal solution, suppressing all duals, and come up with a comparison of that? E.g. sum(i=2..n) (d_i - s_i)/(2^i), where d_i & s_i are the number of dual moves & solution moves respectively occurring at the ith White move. (2020-09-27)
A.Buchanan: I agree with Rosie that 1 ... fxg6 2 c8=B/Sf8 is fatal to the intended AUW. Replacing wSh7 with sBf8 or wBg7g8 does restore AUW, but with an obvious cost. [Legality does not affect soundness, according to the Codex.] As discussed earlier, I think the problem is still Pickaninny as the threat is meaningless. (2020-09-27)

Einsendung zum "Karl-Behtinsch-Gedächtnis-Problemturnier"
PR A.Keirans: "Vier Schritte eines schwarzen und weißen Bauern (Picaninny) in vier Varianten! Im Dreizüger ist diese Idee bereits dargestellt worden, doch sind die unmittelbar symmetrischen Bauernschritte als Echospiel im Problem von Giese eine eigenartige Neuerung, die außerordentlich schwer zu konstruieren ist."
Henrik Juel: Slightly damaged by mate duals, but the beautiful theme is OK:
4 defenses by a black pawn are met by 'the same' move by a white pawn (2020-09-14)
James Malcom: As far as I know, this is the only problem with an Albino echo directly after a Pickaninny on the second move, and not the third as mate. I found this idea on the Frances Eches forum a few days back-https://www.france-echecs.com/article.php?art=20050924201056675. (2020-09-14)
A.Buchanan: Very nice - what year please? (2020-09-15)
James Malcom: I'm unsure of the date, but a look at YACPDB revealed a modern day Pickaninny-Albino echo just like this one-ttps://www.yacpdb.org/#344495 (2020-09-15)
Frank Richter: Jahreszahl inkorrekt - 193 ? (2020-09-16)
Mario Richter: Ja, da hat meine Tastatur geklemmt und eine Ziffer verschluckt. (Kleiner Tip: Wenn es wichtig gewesen wäre, das genaue Datum zu kennen: Ich gebe meist einen kompletten Jahrgang einer Schachpalte auf einmal ein, es hätte sich also eine Abfrage wie "CREATIONUSER='Richter' AND S='Deutsche Zeitung im Ostland' gelohnt, um anhand der "Nachbarprobleme" das Publkikationsdatum zu bestimmen.)

Btw., my typo has made it into the YACPDB too (https://www.yacpdb.org/#381507), so some kind Soul with edit rights should change the date there too ... (2020-09-20)
James Malcom: Mario, I have edited the YACPDB info, so now it is fixed. The solution is also playable now as well. (2020-09-20)

Within hours, the English problemist Michael McDowell sent me a Belén problem that was both a Meredith and a three-mover.

"Or start Na4 on c3 for a 9-piece setting if you don't mind a flight-taking key," he added. Man for man, that setting was later independently also sent to me by Joshua Green. (The key is then 1.Na4)." [P1380105]

"On the subject of a mate in 3 that i showed yesterday here [ P1380114], the duals pointed out kindly by were detected too by T. Krabbé and Joshua Green, and there in "Open Chess Diary" J. Green suggests adding a White Pawn in 'a3', so the Problem is correct, but no longer a miniature and not diverse enough from an earlier MacDowell & Green setting; so the Author (my Chess friend) presents a new "Belén-Theme"- Mate in 3 - Author: Z. Kornin "The Kibitzer's Café" 2004 , Original: White: Ke1 - Ra1 - Bd4 - Nb1 - Pg7, Black: Kc1 - Pa2 - Pc3 #3 (5+3); or in Forsyth: 8-6P1-16-3B4-2p5-p7-RNk1K3 #3"

But castling is illegal! This is because Black's dark squared bishop is a promoted piece and White's king must have moved to let the promotion through.

Henrik Juel: Removing wPh2 might help (2020-09-21)
James Malcom: The illegality of the castling is intentional. (2020-09-21)
A.Buchanan: I guess it is intended as a joke. There are numerous cooks e.g. R: 1. Dh1xDh5 Td6-b6 dann 1. Sb2-d2+! (2020-09-22)
James Malcom: Andrew, the White king is in check from the Black bishop. Ep is the only legal way to resolve it. Your suggestion is illegal. Did you forget to eat breakfast again? :) (2020-09-23)
A.Buchanan: Ha this is just like when I play chess otb - so hard to spot extraordinarily distant black pieces on dark squares :-) (2020-09-23)
James Malcom: Sounds fair enough to me! And the position is legal, not illegal, Andrew. (2020-09-23)
A.Buchanan: I meant "no solution" - and I've classified it as a joke which I think is the composer's intent (2020-09-24)
James Malcom: Quite simply, I agree. (2020-09-24)
Mario Richter: I think the "normal usage" of the keyword "no solution" in the PDB so far is to indicate, that the intended solution fails e.g. because of some hidden defense (which corresponds to the german "unlösbar").
This problem doen't fall into that category! In fact, it has as solution, namely that there is no mate in 3 after the (forced) retractions!
(There are 1064 cooked problems with the keyword "no solution", only 9 "no solution" problems with the label "C+", and for all of the latter either the "no solution" or the "C+" is wrongly attributed.
Perhaps the simplest way to handle the Pedrag-problem is to add "intended" to the KW "no solution". (2020-09-25)
James Malcom: I agree, Mario. It is now doe. (2020-09-25)
A.Buchanan: Yes that's fair. Most jokes follow a template, but this is quite original. (2020-09-25)

"NELS NELSON

We have heretofore published many of Nelson's fine problems and should like to show any readers the more humorous side of his talent. This winter our distinguished friend is spending his vacation in Los Angles. It is with his kind permission that we are publishing this story and problem.

Nels Nelson, born in Denmark in 1871, emigrated to the United States when 12 years of age. He learned the moves of chess in Denmark and began solving and composing problems in 1894. He was chess editor of the Minneapolis State Chess Asccostion, 1911-1912, president of the Minnesota State Chess Asccostion, 19229-1930, and lives at Hopkins, Minn., a suburb of Minneapolis.

AN APRIL FOOL JOKE

A certain celebrated chess master, who we will designate as Mr. "X," while on in the provinces happended into a tavern which was the mecca of the village chess players. Mr. "X," very fond of practical jokes, concieved a plan of sprining on one of the unsuspecting natives. Professing ignorance of the game, the champion of the club offered to teach Mr. "X" its intricacies. After showing Mr. "X' all of the moves with the exception of pawn promotion, pawn takes pawn, etc., and castling, the champion said the following: ""I have purposely ommited three of the manuvers in chess, which to the beginner are somewhat difficult to grasp. They are pawn promotion-when a pawn reaches the eigth rank it ceases to be a pawn but may but it may be converted to any piece on the board and assumes its function at once. It it thus theortically possible to have as many as nine queens on the board at once, and so on down the line." The champion then went to explain the castling on the king and queen side and emphasised the importance of moving the king first. The act of pawn takes pawn "en passant" was then throughly explained and the actual game started with the champio givng odds of queen to Mr. "X," who proved to be a very apt pupil! Mr. "X" lost the first game in short order-walking boldy into a mating net. In the second game he gave the champion quite the battle and won the approbation of that was worthy. In the third game, the champion managed to trap Mr. "X's" queen but had to give up two pieces for it and saw that he had a lost game but continued on in the hope that his expierenced opponent would make some mistake. When the game has reached the postion in the diagram the champion was dumbfounded to hear Mr. "X" announce mate in three moves. "Impossible!" exclaimed the champion. "You should win, of course, but mate in three cannt be done." "Well, if you have interpreted the move and rules correctly, I am certain I see a mate in three," said Mr. "X." "Of course I have interpreted the rules correctly, exclaimed the now irate champion: and I will lay you a wager of dinner for the members of the club that you fail to mate in three moves." "Done!" cried Mr. "X." By this time nearly ever member in the clubwas watching the game with interest. Now, who won this wager? It will be shown in the solution April 11."

11/4/1937-https://www.newspapers.com/clip/25408721/chess-by-herman-steiner/

"SOLUTION TO PROBLEM 760 by N. Nelson: "April Fool Joke."

White: K. on K1 R. on Q7, and KR1: Kt. on KB7 and KB8: B, on QB5: P. on K7, KKt5, and KKt2, Black: K. on KKt2: R. on KKt1: Kt. on K1: B. on KKt8: P. on KR4. (Wh. 9: BL. 5.)

Many members of the club were very fine players and felt their champion would win. Curiously, most of them were pulling for mr. "X," as the champion was somewhat of a braggard and if he won they felt they wouls be hearing about it for a long time. They were, therfore, keenly alert when Mr. "X" started to proceed the game. "My first move is pawn takes en passant," said the smiling Mr. "x." "Of course, I anticipated that move," replied the champion, "and I shall meet it with king takes knight." Oh well then I shall make for my second move, castle: taking the bishop," continued Mr. "X." "This move is according to your definition of castling, perfectly legitimate, as the king moves first, and the bishop being on the knight squar, certainly is subject to capture." "Well," replied the champion, "I must say your interpretation is far fetched, but I will grant you even this point as I fail to see how you mate on the next move: you evidently overlook the fact that when you promote the pawn the king will be able to capture it. Of course, I am forced to interpose my knight and it is pinned, but the king will still be able to take care of that promoted pawn. " Well," smiled Mr. "X," "I shall, however, mate you by pawn to king eight, discovering check, as I shall claim a black knight for the promoted pawn, which, according to your interpretation of pawn promotion, is perfectly legitimate. You stated I might choose any piece on the board and, of course, as the black knight is the only piece that will mate, I naturally selected it."
Exit champion.

We are publishing the best solution sent in my Ladderite L. A. Post, incidentally only two others solved this April Fool Problem.

Problem 760 to complete the tale that Mr. Nelson started to what I believe to be the logical solution according to the rules given by the local champion.
1. White: Pawn takes pawn "en passant" check.
The local champion then captured the white knight reposing on his "bishop two."
1. Black: king takes knight.
"Now," continued Mr. "X" "I understand to quote you, the king moves firstl in castling."
"That is correct," agreed the champion.
Thereupon Mr. "X" executed the move in the prescribed manner by first moving his king to his king knight square and removing the champion's bishop and then setting his rook down on his king bishop square calling check.
The champion was nonplussed, for in stating the rules for "castling" he had failed to forsee a circumstance of this kind. He was forced to admit that, according to his own statement, such a move was possible But seeing in spite of this that it was still impossible to checkmate on the next move, he conceded the point and interposed his knight.
2. Black: Knight to king bishop three.
"Did you not say," resumed Mr. "X," "that in 'pawn promotion' you could reclaim to any piece on the board?"
"That is correct," conceded the champion, "but since you insist on taking me literally I might add that there is no "queen' on the board you may claim in one."
"In that case," stated Mr. "X," "I will be equally generous and present you with a 'knight.'"Whereupon Mr. "X" removed the pawn at king seven and placed a black 'knight' at king eight discovring checkmate to the champion's "king."
"Such a thing is impossbile !" cried the outraged champion.
"Not at all," replied Mr. "X," "for according to your statement that "upon reaching the eight rank a pawn be converted to any piece on the board and assumes its function at once.'"
To this the other members agreed. So the champion held a dinner in honor of Mr. "X," the most apt pupil he had ever taught.

Resepctfully yours,

Henrik Juel: Some help is needed here, James
At least for me (2020-10-01)
A.Buchanan: Hi Henrik I am guessing it’s a cheatyface Valladao:
1. gxh6ep+ Kxf7 2. 0-0+ Sf6 3. f8=sS#
No proof for the ep, castling with capture and promotion to black officer (2020-10-02)
James Malcom: Bingo Andrew! (2020-10-02)
Henrik Juel: Even though I ought to stand by my fellow danish author:
This is a most crude 'joke' problem, especially the 'castling' with capture (2020-10-02)
A.Buchanan: It's kind of a running gag: three silly jokettes which do combine relatively harmoniously (2020-10-02)
A.Buchanan: 1. ... Kf6 allows a short mate, robbing White of the Valladao. 4nNbn/3RP1kN/8/6Pp/8/8/8/4K1bR is the best I can find, fixing the problem, and with less material (2020-10-02)
A.Buchanan: I was hoping that someone would spot that I have shifted a unit to h7 - i.e. the e.p. is even more Foolish :-) I claim it "improves" the problem because currently the e.p. *might* be legal :-) If this is too crude for some, then 4nNr1/3RP1k1/6N1/4P1Pp/8/8/8/4K1bR works. Note you need sTg8 to prevent 2. Sh8#, but wSg6 is blocking g-file, so wBg2 is still free to find other duties on e5. (2020-10-03)
James Malcom: Excellent improvements, Andrew! (2020-10-06)
A.Buchanan: Thanks James: do you think the one with Sh7 is excessively silly? (2020-10-06)
James Malcom: Yes, 'd say a bit too silly. (2020-10-16)

Solution text from the 2/1899 issue: "A clever rendering of this "triple idea." It will be seen that Black cannot play simply 2.R-Q sq on account of 3. Q x Q ch."

James Malcom: I found this most excellent early Valladao while ago, but only today did I finally find it again. This is the second one that I've found, i.e. P1380523

Is this the second oldest known Valladao after the 1867 P1360420 found by Keym?

The mainline should be C+, with the "legitimate" ep key, but with many dualed sidelines. (2020-10-14)

zunächst mit sSe3 abgedruckt, Korrektur 11.06.1943: "Im Problem No. 6 ist uns leider ein Fehler unterlaufen. Auf E3 steht nicht ein schwarzer Springer, sondern ein schwarzer Bauer. Wir bitten um Entschuldigung."
Das dürfte immer noch fehlerhaft sein (mit sBe3 geht einzügig 1. Tf4#!), mit sLe3 aber korrekt.
