This one is the first with orthodox pieces and only one fairy condition. 11.Qa7 is necessary to block the "a" Pawn in a6 so to force 13.Qh7.

1. Geoff Foster says:

Is it worth extending the problem so that the pieces on the g- and h-files move into place at the end?

3. Luce Sebastien says:

Dear Geoff,

I had also the idea to make a longer problem, for instance with white Pawn a5 in a2, white Pawn
f6/f5 in f2/f4, white Pawn g5 in g2 and maybe white Rook g6 in a3 (?!) to propose as the key move 1.Ra3-g3 but…
…as I tested my problem in 38 mn with Winchloe, I had not the patience to do it with a longer problem, and also there is the question “is it interesting ?”

But if you succeed to test a longer (interesting) version of this problem, I propose you to co-sign it ! 🙂

I hope you are fine Geoff, give me some news by mail, you are a friend !
Best

I found a setting which i tried testing with Popeye yesterday. It took hours and hours and finally, I had to come out.

If sound, it should be interesting because the final position is well covered.

• Joost says:

Doesn’t work, after 44. g5 white must play Rh6.

• Joost says:

Furthermore, after 40. f6, white must play with Rg3.

• S N Ravi Shankar says:

Quite right. Further, 9.b5xa6 is also possible. Another version has been sent to Julia for publishing afresh.

5. S N Ravi Shankar says:

I just noticed that wR can move along the rank! Perhaps wK can be shifted to b1 or wR can start from a3 – as the author points out –
with change in stipulation.

6. Luce Sebastien says:

Dear M. Ravi Shankar,
your setting is very interesting !
If you have more patience than me to test it, I encourage you to do it (with co signature at the end of course !).
M. Pierre Tritten told me that it is not necessary to have the famous C+ to present a new longer version. I don’t know your opinion about that ? Please inform me if you find new versions :

7. Luce Sebastien says:

by the way, I notice that in my original version,
black c5 is probably not necessary: with white Pawn c4 instead of d4 it seems ok ! I have to test it…

• Joost says:

C+ in 5 minutes (popeye 4.76 SVN version) with d4 to c5 and ser-==21

8. S N Ravi Shankar says:

In my version (See solution to 1163.1), the play up to move No.23 is similar to 1163 which is C+. The position reached after blacks 23rd move is also C+ (Popeye -v4.63)

9. S N Ravi Shankar says:

Here is a version of 1163.1.

Remove the rook, add a wP on b5 and shift d-pawn to d4. -Ser-==31

solution finished. Time = 1.510 s

My thanks to Geoff Foster for his response to 1174.

• Joost says:

9 white pawns?

10. S N Ravi Shankar says:

oops!I did not notice it. I should have used a chess set!

• seetharaman says:

🙂

11. Luce Sebastien says:

Dear Ravi
your version with 9 Pawns interest me !!
I have an idea (for the future) to write an article with the title “OUTLAW!” with interesting but illegal positions !
Could you send me by mail the pos. ?
I invite all composers to send me also their positions in the same style !
Here is my mail :
