shortest game not by mate

This is similar to my last two questions, but hopefully this will be a lot more difficult.

Excluding by checkmate, what is the shortest game possible? This excludes games where players resign or agree a draw. For example if a player resigns on move 2 or both players agree a draw on move 2 this would not be included. The shortest game is the minimal number of moves.

Hint: It is less than 15 moves. If no one gives the answer by tomorrow (with the reason) I’ll give a clue tomorrow, and give the answer on Friday.

What is your problem, mate? You looking for an exceptional thread or what? This post is useless and you know it.

I guess it will be in the 10th move, the fastest stalemate I can think of

No checkmate, no resignation and no draw agreement?  Then it would be the shortest stalemate.

Oops you posted before me tennisbal. You thought of that stalemate? Wow.

Pfff... The shortest draw can be obtained by the threefold repetition rule:

1. Nf3. Nf6. 2. Ng1. Ng8. 3. Nf3. Nf6. 4. Ng1. Ng8.

After the last move of Black the starting position is seen for the third time on the board, which make the whole game a draw.

tennisbal's game is cute! :-)

White's cell phone goes off just after he makes his first move and his game is forfeited after 1 move. Not a checkmate, resignation, or draw agreement. But surely not the answer you are looking for.

 That's pretty much a draw by mutual agreement. But yeah I guess it's the shortest possible game that's not a resignation, draw by mutual agreement or resignation.

There would be multiple answers if this solution is allowed.

Stupid problem really.

I think IPA-Ray's is the answer I was least expecting! I agree Tennisbat's stalemate is cute.

The answer I was thinking of was by threefold position repetition when the draw does not have to be agreed but can be claimed. So the answer is 4. One example of moving the knights backwards and forwards to achieve this was given by jazzdream.

Tennisbal's solution was actually composed by Sam Loyd.


two players in norway copied it in a tournament and both players got 0 points instead of ½ for the too obvious draw.

I know an other solution. It is from Sam Loyd. The solutions from Sam Loyd I found in the (German) book Schach und Mathematik, by J. Gik. (Schach und Mathematik means chess and mathematics)

 

 

Pleas note that the white pawns are different from the solution above, the black pieces are in the same positions.
An other solution with less than 15 moves is by Sam Loyd, too:
Please note, that all peaces are still on board. This game I saw some years ago in the German magazine "Kölner Stadtanzeiger", too. There it was commented (I translate it to English): Now white thought what to to. For he thought very long he ran out of time. So black claimed his victory. But is it right? Does any rule exist that one has to claim a draw by a stale mate?
The book Schach und Mathematik shows an other solution. This time black has the last move and white is set stale mate. In the book are two mistakes. Here is the corrected solution.
The next solution from Schach und Mathematik is 19 moves and has an other curiosity. First I show the solution:
The moves are nearly symmetric by center and both sides are stale mate!
Another solution with high symmetry:
Both sides are stale mate!
Draw by eternal check:
I know that I answered questions you did not ask, you asked for the possible shortest draw game. But I hope you can enjoy my answers and would have asked for them.

My initial thought was threefold repitition, like this.

Next question... shortest draw by best play (assuming best play leads to a draw).

why didn't he take the queen with his rook??? EVEN A BEGINER WOULD KNOW THAT


 that is the reason both players copying the game got zero points each instead of ½ each because it looks too staged.
