[Retros] CC game

[Göran Wicklund]

In my intended solution, there are two double checks. I forgot to indicate those:
 
35. ..[+]
36. [][+]
37. [][++]
38. [x][+]
39. [x][++]
40. [x][]
41. [][#]
 
If correct, it may be possible to add an extra double check:
 
39. [x][++]
40, [][]
41. [][++]
42. [x][]
43. [][#]
 
/Göran

Dear Goran,

>35. ..[+]

>36. [][+]

>37. [][+]

>38. [x][+]

>39. [x][+]

>40. [x][]

>41. [][#]


The computer states that there are several ways to finish the game like this, e.g. 

35. ... Bc8-b7+ 36.Kc6-b5 Pa7-a6+ 37.Kb5-b6 Bg3-c7+ 38.Kb6xc7 Ra8-c8+ 39.Kc7xb7 Rc8-b8+ 40.Kb7xa6 Kd4-c5 41.Ka6-a5 Rb8-a8#

35. ... Bc8-b7+ 36.Kc6-d7 Bb7-c8+ 37.Kd7-e8 Bc8-d7+ 38.Ke8xf7 Bd7-e8+ 39.Kf7xg7 Bg3-e5+ 40.Kg7xg8 Be5-f6 41.Kg8-f8 Be8-g6#

and some more.

As for double checks, I think that there is a unique beginning that contains 4. ... [++] 5. [] [+] 6. [x] [x+] and then possibly 7. [][] 8. [x+][x] 9. [][#], but this was done by hand, so I cannot be 100% sure.

Best wishes,
Nikolai
