[Retros] Mushikui Reconstruction (castling both sides)

[Juha Saukkola]

Why not to make your notation shorter:
23,23,24,52,33,22,45,25,25,45,33,55,42,42,52,53,54,4

Hi everyone,
 
Today I constructed a sequence that forces both O-O and O-O-O. Here it is:
 
1.** *** 2.** *** 3.** **** 4.***** ** 5.*** *** 6.** ** 7.**** ***** 8.** 
***** 9.** ***** 10.**** ***** 11.*** *** 12.***** ***** 13.**** ** 14.**** 
** 15.***** ** 16.***** *** 17.***** **** 18.****
 
This one is insanely hard, so I'll give you the solution below.

P.S.
The intermediate stage 1.** *** 2.** *** 3.** **** 4.***** ** used in this 
problem was found by Mario Richter. Thanks for his work on this subject.
