Topic Name? "Mate in ...

fascinating

Nice concept

Nice but you might extend it with one of drdos7's recipes. As you can see in a number of his posted longmovers (don't know exactly in which topic) the queen can single-handedly drive a black king to a mating spot from many squares in this type of position. For instance assume that the final pawn is on f6 rather than g7 after the queen sac - obviously requiring redesign of the puzzle - then there is still a good unique fastest king hunt ending in mate!

Here, "the queen can single-handedly drive a black king to a mating spot from many squares in this type of position". However this can not make it to a puzzle-form.

Looks like a mate in 37 (or less) if I'm not mistaken:

Welcome to my humble domain Mr. @drdos7! .

Now, I have just made another 1. I hope it suits the taste of the beholders.

Another nice one, This one is rather amusing. I like the idea of the White Knight there to assist the White pawn in Queening, also amusing is the White pawn on the g6 square which is the square where the Black King ends up getting mated at. Looks like a mate in 28 (or less).

As you see, drdos7 also has powerful computing tools to solve such endings! My idea was not that you would design a completely new problem but to keep the general structure of the original and attach a longer tail end to it! If you want to go big keep in mind that drdos7's analysis does not concern itself with solution duals so you can't know if they are there! They would take the problem out of the standard composition domain and place it into the mathematical tree search environment where all (shortest) solutions are equal and duals add to the fun. Very much like the constructions you started with a few years ago! I am not of that school and would suggest you limit yourself to unique white choices and unique move orders which is much harder as you know! But that's up to you of course!

Another amusing detail is that the queen is returning back to her birthplace at the end of her journey. Home-Coming-Queen if like  

Master I am not as proficient as I was back then in regards to constructions, which are currently in the range of "very few and far between"s. However once-in-a-while I feel inspired and things happen.

And in regards to @drdos7, who not only has powerful engine tools but also has very powerful sensors as to detect the twisted humor I deploy in the constructions.

And YES the dual-free-puzzles are harder to make, yet they could be easier to solve.

Well, I don't think so because there is no recipe for solving a dualed puzzle on chess.com. After all, it can only handle 1 correct move and if the solver chooses another correct move it will be rejected and he will not know whether it's actually wrong or just a dual. That's where guessing takes over. The issue with the mathematical approach is that you first need to know all dual moves and then have a way to approve of them when they are chosen. Even with a better puzzle interface than chess.com's, dualed solutions remain hard to manage when solving. They are more suitable for mathematical research!

Btw, the reason that compositions require 1 solution is not just for solving. Creating a challenge with just one working move on every turn is a show of competence by the author. The #1 topic in compositions is the composer, his design and his technique. The solver and his goal is probably in tenth spot

Master, I play many chess games daily and actually the game itself is one giant puzzle to solve all the time. Sometimes there are multiple solutions and sometimes there are single-move situations. So it is not purely math.

I make artificial-chess-simulations. Sometimes it is just a puzzle, sometimes it is more than just that. It could be a way to convey my own situation. Here @drdos7 manged to feel beyond chess and he could see there was humor involved and if you did not notice it, well, I just don't know what to say...  However the last 1 involved a personal meaning which is hard to see for others... I have been dealing with toothache the last couple of days and the white pawn on g6 came to me as a tooth that needs to be pulled out and later replaced, symbolized by the black king. So there is a deeper level of things, and that sometimes detracts from just a chess-puzzle experience. So I apologize for that, Master.

And by the way the w-queen is my dentist. She has dignified futures so perhaps there is something royal there. Who knows.

And by the way the knight sac... is the cost of going to the white-queen, pull out a white pawn and have it replaced by a black king. Ok, I'll show you a picture and you'll see my point.

The rest is about the struggle of the white queen wriggling from place to lace to replace a white tooth with a black-king. Each move counts for a minute so 28 minutes (or less).

The humor is that is didn't examine your last construction! I only commented on the one sentence I quoted because I didn't think the second part of that statement was true.

Btw, I do not subscribe to the mathematical viewpoint because compositions are a higher level system (model or meta-system) than the deterministic chess game environment and its objects and operations are not part of (basic) game theory. Though, some day, AI-systems will include them. So you got my viewpoint upside-down!

And I do sympathize with meta-chess considerations which are an essential part of the artistic universes of composers. But artistics are always implemented on formal base systems like the chess rules just as paintings are framed by the physical laws for paints and canvases. For compositions there are also the laws of compositions which are totally designed as a foundation for artistic chess creations unlike chess games which are governed by goal/profit-driven mathematical game theory!

Iblish gandi chya puzzle aahe hs

My friend, is this Urdu or something? So no Engelski? Nehi Zabani Sahib, or something?

- "Doost, nehi afkari gandi, otherwise "bandi". I believe I saw that in a Bollywood movie.

This is an international forum, where English is the main language. So either speak the language or keep your ideas to yourself.

Much obliged!

Very unique idea. White just needs that extra move to keep the king trapped.
