    But the bK has a choice of 6 squares each time, which is especially bad because it is just a waiting move (White is already in stalemate).

    Yes. Big weakness

      I dare to disagree with the automatic downgrading of helpself problems having multiple final black moves. More specifically, in this case – the point is in the critical positions, i.e. in the positions after the last move of White. In spite of many moves available, there is no way to disturb stalemate net – that is a kind of paradox.

      I know some helpself experts disagree and indeed, in hs# where final black move is included in the main idea, it should be unique. But every composition should be considered separately. Automatic rule in this case is not justified in my opinion.

    In the selfmate (selfstalemate) problems are moves of Black a variants, not duals. See my another hs= with last move K~, http://www.problemschach.de/harmonie/h138.pdf, p.42-43, 3. Prize and a comment by judge.

    Last move duals could be eliminated by setting problem as a h==4.5 without BK, but BK is utilised in the previous moves of all the solutions!

  6. shankar ram пишет:

    Such duals also possible in a hs#, but I’ve not seen an example yet!

    I propose to write down the condition “4 solutions” as “4.1..6”, for example:

    -“But every composition should be considered separately.”-
    Yes Juraj, in principle. Sergey’s example nicely demonstrates the point – 5 black pieces can move and can’t avoid to attack the existing wK’s flight.

    Multiple utterly banal and boring TEMPO MOVES indeed should be “considered separately”!
    Of course, as a TERRIBLE FLAW that HUMILIATES the delicacy of tempo-play.

    Juraj, just to make it clear – my ‘opinion’ was not about Vaclav’s problem but about ‘what should be considered separately’ and what should not.

    What is a paradox and what is not?
    White Kd3; Black Pb4,Pa2,Pb2; H==2
    Put bK e.g. on d5 and there’s “paradoxical” hs=2.5 with bK’s “star+cross”.
    Or, should we add more black pieces to “increase the paradox” of many final moves which “cannot disturb the stalemate”?

    I simply don’t understand what you’re talking about. I hope at least YOU know what is ‘your opinion’.

    Interesting debate about H# vs S# conventions when applied to HS#. There does seem to be a difference between a final move such as a random battery opening as sometimes happens in the last move of a S#, and a purposeless move in an already-achieved stalemate net as here.
    In any case…I would also consider as flawed the stalemate net itself: it is not a model (b5 guarded by two eagles in the first line). It’s an inevitable feature of the pin; without the need to pin the EAd5 could stand on e5.
