Edit: to be precise it wouldn't matter as for a mate in x problem, in which case the one and only solution in x moves matters, any move leading to a longer mating variant would be ok and not fit the term dual, as for a study, that's another category.
Guess I mixed that up, sorry

But not quite a miracle, it takes just one more triangle- manoeuvre.

Hi,
thanks. So this problem is also solvable. What is your

Thanks Peter!
Debugging is twice as hard as writing the code in the first

Yes, it was maybe more meant as a chessproblem. Die Schwalbe is mainly known I think for problemists? It says "deutsche Vereinigung für Problemschach." I have not found yet who exactly was Mr. Breuer that the memorial was dedicated too. I saw a Josef Johann Breuer, also a composer of chess problems but he died in 1981 so that probably was not the Breuer of the memorial.
Regards, Eelco

Some years old 12core Intel but the hash is newer and the 32G might have helped here too.
Hyperthreading on.
Thanks for bringing the position and a happy new year to everybody!
Peter.

I let it run a bit longer yesterday but it did not get the Mate in 29 even at a depth of 81. Patience ran out and I stopped it, but, on the other hand, it was a good stress test as well for the program. It's close enough to 29 that I don't think it is a real bug, but it is not really tested of course. On really big hardware you can get deeper than this in a day or so.
Happy New Year from me too everyone

Michael: I let Komodo 9 consider the position for 35 minutes and the best it could come up with was Kc5 0:00 However when I fed the moves 1 Kc7 Ba3 into it this is what it displayed. Sure it doesn't get mate in 29 and yes it needs direction but still it's a start.
