Subject: Solution to D27

You would think that after D29 I would know better, but no - I'm going
to publish this solution on my own bat. (I'm sure Steve will put it
through the computer to check it, before sending it to George, but
I've double checked it myself, and I'm confident I got this right.

Steve's only contribution so far is to draw my attention to the problem
(observing that he thought it had a similar theme to D29 - he was
right).

1.  +RC x 12k, Ln x 12k
2.  +B x 12k,  K x 12k
3.  L - 12d+, SM x 12d

 or 3. ..., Ky - 12j, 4. +R x 11k mate
 or 3. ..., K - 11l, 4. +VM x 11k, Ky x 11k 5. +B - 10k mate

4.  +B - 11j,  K x 11j

 or 4. ..., K - 12l/11l, 5. +B x 11k, Ky x 11k 6. +R x 11k mate

5.  +VM x 11i,  K - 10i

 or 5. ..., K - 12i 6. +VM - 11h, K - 12h 7. +VM - 10j, +SM x 10j
    8. +R - 12k mate
                 or 6. ..., K - 12j 7. +R x 11k mate
 or 5. K x 11i 6. +R x 11k
       and we rejoin the main line
 or 5. ..., K - 12k, 6. +R x 11k mate

6.  +VM - 11j, K x 11j
7.  +R x 11k,  K - 10i

 or 7. ..., K - 12i 7. +R - 11h, K - 12j 8. +VM - 12l mate


8.  +R - 10j,  K - 9h
9.  +R - 9i,   K - 8g
10. +R - 8h,   K - 7f
11. +R - 7g,   K - 6e
12. +R - 6f,   K - 5d
13. +R - 5e,   K - 4c
14. +R - 4d,   K - 3b
15. +R - 3c,   K - 2a
16. +R - 3a,   K x 3a
17. +VM - 3c,  K - 2a
18. +S - 1a mate

a mere mate in 35 by the Japanese count :-)

The difficult bits to find were the Lance sacrifice at move 3 (note
that it must not capture the SM, as the Rook then becomes a defender),
and the final sacrifice of the Dragon King.
