C1 is still troubling for me as well...just can't see solution as of now.
Same with Ribannah's latest one. Seems impossible to mate in two moves. Aaargh!

C11:
a) 1.c8N+ Kb8 2.c7++
b) 1.c8B Kb8 2.Nc6++
c) 1.c8R+ Ka6 2.Ra8++
d) 1.c8Q Kb6 2.Qb7++
Really cool one. :up:
Cylinder (C12?) Qd7 Qd8+ Bc5++

If you mean 1.Qd7 Ka8 2. Qc8+ Ka7 3. Bc5# : no, the Black king will escape to the h-file.
Playing on a cilinder means that the board wraps around from side to side.

Care to explain a bit more this cilinder thing?
EDIT: Nm, found it.

Warning!
Follow the link only if you're really sure that you won't solve the riddle. It is much better, if you solve it yourself, trust me! Right, Nebuka? :-)
Btw, some of you tend to use the word "stalemate" wrongfully. Its meaning is that one of the players has no legal moves (and its king is not in check), hence the game is draw.
But a draw can happen for several other reasons as well. (repetition, perpetual check, moves rule, agreement, no mating material, theoretical draw position).

This is NOT a valid move. That is NOT a CHESS puzzle. Please note that next time so that we don't waste hours of our time trying to solve something that can not be solved. Thank you.
FYI, here are the official rules of a game called CHESS. Read it since you don't seem to know what the rules are:
http://www.fide.com/official/handbook.asp?level=EE101Quote:
When a pawn reaches the rank furthest from its starting position it must be exchanged as part of the same move for a new queen, rook, bishop or knight of the same colour.

Who said it was a chess problem?
And I'm a chess player, thank you.
And btw, it's very much a chess composition.
Here's the story for the problem (C1), btw.
There's a hungarian book containing lots of chess problems, it's name is "The return of detective En Passant". There are lot of stories. This is one of them. There is a war between the Sirius and Earth and the former ones use androids as spies. A spaceship gets an important mission that would decide the war, but right after their departure they notice that one of them was killed and changed for a droid. Of course they don't know which one. So the captain gives them chess problems but the sirians trained the andriod well and it solves them just as fast as the others until this last problem comes...
The android is hopeless cause he can't escape his program's rules - but humans can. Planet Earth is saved

That is a nice story, was everyone on board female? (Changing the rules of the game when the standard rules don't seem to work for them? )
You've made no note such as "this is not exactly a chess puzzle", or something along those lines. Just an FYI: I did think about different possibilities such as: making a black piece, making a king, or stopping a pawn at a8, but I didn't even bother to check any of those because you listed it as a CHESS puzzle, and those are NOT chess rules. You know you can bite someone's ear off on the ring, but guess what? Unless your name is Mike Tyson, you don't do it because you respect the rules.
Just make a note if one of your puzzles is not a chess puzzle. Some of Ribannah's puzzles do not use standard rules, but he made a note of it, so we can still enjoy solving those without wasting our time.

here are the official rules of a game called CHESS.
The rules of chess, including the rules for promotions, have changed a lot over time. Some endgame positions that were a draw less than 20 years ago became a win at one time, and then a draw again.
There are a lot of alternative rulesets in chess compositions. They exist because some ideas cannot be demonstrated within the rules for ordinary chess games.
You will find alternative boards, pieces, objectives, pretty much everything. All of this is still considered chess.
Normally an alternative ruleset is indicated when a composition is shown (helpmate, CIRCE, fairy chess etc.) but in some obvious cases, typically jokes like C1, that would immediately give away the solution. If it read "mate in two, pawns are allowed to promote to kings" would it be interesting?
What is far more striking here (she says) is that in such a position some people still expect a normal solution.

A point is, that a chess variant is still chess.
If you are someone who normally just plays the game, this is new to you. But now you know.

I liked the composition, for what is worth.
Would never figure it out, but still like it.
Anyway, Ribannah...please post solution for your latest one, I'm completly stumbled there.
Pawns on c, and e columns seem completly useless, as moving them anywhere, black is in stalemate. And as second move, they can't checkmate. F pawn as well as king can't move either, as again stalemate.
So, only queen and g pawn.
1. g4 Kh4
No mate in second move.
1. Qg8,g6,g5 - again stalemate.
1. Qh8,h7,h6 Kg4 - no checkmate in second move
I think same for all other queen's moves.
Kinda hoping you made a typo, but think there is a solution, just I don't see it.
Cheers.

Remember that this one was posted as a comment on C1.
Also, as a general rule, everything that is present in a composition has a role to play.

ahahaha, lol, I solved it.
1. e8BK Kd8 (BK = black king)
2. Qd7## (double checkmate)
PS: See? You didn't say "You can make a black king with the pawn", yet the hint you gave us about this puzzle not using the standard rules was really needed.

Well, that hint was not needed!
Anyone who takes a look at the board can realize in about 10 minutes that there is no legitimate solution. You have to let the black king to either h4 or g4 and there is no way to mate it there.
Any luck with my problems guys?
Anyways, here are the diagrams for C10 and C12 to refresh your memory.
This is C10: (white to win)
And C12 with the cylinder board, I tried to be constructive and placed two boards next to each other to make it more visible (might help a bit). Actually a lot I think, because there is something about chess problems... some kind of mathematical thing you know...
