h#4
0.2.1...
Yuri Bilokin: you can see h#3 1.b2 Ka3 2.b1=R Ka2 3.Rc1 Se3# (2022-12-10)
Henrik Juel: I think it is cooked, because of the solution in 3.0 moves
It might be saved by changing the stipulation to something like
h# in excactly 3.5 moves, 2 solutions
I am surprised to find that both Popeye 4.51 and 4.61 miss this grave flaw (4.79 is no better)
So Popeye is no better for helpmates than Euclide and Natch are for proof games: You must test for shorter solutions explicitely; the programs do not provide them (2022-12-10)
A.Buchanan: Hi Henrik I’m a bit confused. Are you saying set play for a helpmate is always a cook? For a h#3.5, Popeye certainly picks up all solutions of the form h#2.5 but will only find a h#3.0 if set play flag is enabled. Helpmate analyser has the same philosophy. When they talk of “short solution” for helpmate, I think they mean premature ending not “delayed start”. (2022-12-10)
A.Buchanan: A premature ending must still end with a white move, which is why the engines only pick up those solutions which differ from the intended one by a whole number of moves (2022-12-10)
A.Buchanan: I agree the sloppy old Codex is ambiguous on this, as on many things, but this is certainly the interpretation that I believe others hold. If not, it would be impossible e.g. to begin a solution with a pure tempo move (2022-12-10)
Ladislav Packa: Andrew, I agree with you. In this particular problem, for example, just add bPb5 and it's a correct H#3,5*. (2022-12-11)
A.Buchanan: Hi Ladislav. Thanks but I don’t think you do agree with me. I say the current problem is fine indeed excellent. No fix is needed - adding that unit loses miniature and means one mate is no longer ideal. I tried to explain to Henrik why engine developers take the stance they do, but he hasn’t responded. To me this is not a controversial point - it’s kind of obvious (2022-12-13)
Henrik Juel: Hello Andrew
You are probably correct in saying that the helpmate solvers only search for solutions with the right side starting (e.g. White in a h#3.5) (unless the set play is explicitely asked for also)
I still think that here the solution in 3.0 is a cook, and Ladislav seemms to agree... (2022-12-13)
A.Buchanan: Hi Henrik. Would you say that a #2 where the diagram position is a zugzwang is unsound? It’s exactly the same logic as you are applying here. I’m a bit surprised you take this position. There is no artistic gain - it merely prevents blocks cool stuff e.g. any key in a h# from being a tempo move. My view is that across all genres, set play is a completely separate concern from short solutions. A composer is allowed to constrain the problem by saying implicitly who has the move. With respect, I think Ladislav is confused. (2022-12-13)
Ladislav Packa: Andrew: it was just an example, I didn't want to fix the problem. It was to support your claim that the shorter solution is something like a set play.
Henrik: you are not right. I am giving a specific example, P1355854. It's really humorous that this problem was originally kicked out of the tournament because it also has a shorter solution h#3.... (2022-12-13)
