[Retros] Mushikui Reconstruction (checkmate)

[Juha Saukkola]

Hi!
 
If you want to find something "thematical", try to find some math patterns like
2 3 4, 2 3 4 ,2 3 4,.. or
2, 2 3, 2 3 4, 2 3 4 5, 2 3 4 5 6 or
2 2 4, 2 2 4, 2 2 4,..
 
Even this have more content than your problem below:

Hi everyone,
 
After I constructed an example that forces a draw, I continue to work on 
valid mushikui sequence that forces checkmate ending, again without any 
extra assumptions in the stipulation. I found this to be a very difficult 
task, and I tried to compose such sequence for two whole days, desperately, 
yet still without any success. But finally this morning I constructed my 
first example that does the job.
 
 
1.** ** 2.**** ** 3.** **** 4.** ***** 5.** ***** 6.** *** 7.***** ** 
8.***** *** 9.***** *** 10.***** *** 11.*****
 
 
I can hardly imagine that there could be a shorter one that also forces 
checkmate. But still I'm eager to see if anyone can come up with a shorter 
one!
