35. ..[+]
36. [][+]
37. [][+]
38. [x][+]
39. [x][+]

Dear retro-friends,

First of all, sorry for the late reply and thanks for examining the two puzzles. With the priceless help of Mario Richter, here is a correction of the longer game in 36.0 moves:

1. [][]
2. [x][+]
3. [][x+]
4. [][x+]
5. [][x+]
6. [][+]
7. [][+]
8. [][+]
9. [][x]
10. [x][]
11. [x+][]
12. [+][x]
13. [][+]
14. [][x+]
15. [][x]
16. [][+]
17. [][x]
18. [x][x]
19. [][+]
20. [][]
21. [][x+]
22. [][x+]
23. [][x]
24. [][]
25. [x+][]
26. [+][]
27. [+][x]
28. [+][]
29. [+][]
30. [+][x­+]
31. [][x]
32. [][+]
33. [x][+]
34. [x][]
35. [x][]
36. [][-#]

Or, in Mario and Gerd's notation, [-*][-*][x*][-+][-*][x+][-*][x+][-*][x+][-*][-+][-*][-+][-*][-+][-*][x*][x*][-*][x+][-*][-+][x*][-*][-+][-*][x+][-*][x*][-*][-+][-*][x*][x*][x*][-*][-+][-*][-*][-*][x+][-*][x+][-*][x*][-*][-*][x+][-*][-+][-*][-+][x*][-+][-*][-+][-*][-+][x­+][-*][x*][-*][-+][x*][-+][x*][-*][x*][-*][-*][-#]. 

It uses the same 9-move opening; intended play is below. I composed the first two by hand, but for this the computer claims it is sound, so everything should be fine.

Some thoughts of mine on the CCC-genre:
a) This is surely not a record. To say the least, ending the above game with 35. [x] creates a non-mate determined position, so it should be possible to squeeze more than 3 more single moves out of it, but this was right about where my patience wore out. Anyone aiming at 49.0?
b) None of the games constructed till now makes any use of double checks, and they seem to be quite forcing in a game. Any ideas? 
c) I think that this genre could have themes on its own. For one thing, the above game contains a determined promotion, which seems interesting to force. Another point is constructing what I call "waltzes" - long sequences of the type [][+][][+][][+]... in which the King moves so that one and the same piece is able to check him again and again. Waltzes are usually determined by the fact that at the end either the King or the piece should occupy some special position - probably where they can capture something. Knights and Bishops produce very charming patterns, and it would be very enjoyable to see longer waltzes in correct puzzles. One example of what I mean by that are moves 17-20 in the cooked game, and shorter ones - moves 28-30 of this one and probably 19-21 of Gerd's game (I haven't solved it yet, but I intend to). 
d) Besides, no one of us used castling for the sake of the record; but probably castling would make it technically easier to implement various meaningful themes, instead of just pile up numbers.
e) Finally, something a little off-beat: The CCC-genre is very, very finite. For instance, the number of possible 9-move strings is roughly 400 000 000, a good machine could enlist them in a reasonable time, and it is hard to believe that many of them would produce determined positions along the way. Yet, such a countable thing quickly obtains record chases, technical methods, themes, etc. It is tempting to think of this evolution as a small model of the development of the art of composition in general; I think that examining such a model would make many historical processes clearer.

Best wishes and hope someone goes on from here,
Nikolai
