Stalemate

Wow, 18 moves! That's genius. Do you know if this is the fastest double stalemate possible, or just the fastest yet discovered?

But black has other moves than checkmate. He could move his knight elsewhere and not checkmate white in one. The idea was to create a position for which the only legal move was checkmate whether white or black to move.

What an interesing topic. Now tracking!

those stalemates were all done on april fools day at some silly tournament foolish enough to play on such a fine day.

What is the goal of this position?

10 moves?  This is the fastest I thought of by myself:

OK, here's a funny stalemate:

The criteria for draw by repetition is triple repetition of position not move. So in the game given, the draw is claimable after move 4.

I've just realized that I am an idiot.

I can't see any for black but can for white.

Black can play Nxb6#, but it's not forced.

 . . .

Oh yeah. Somebody should have realized this long ago.

I thought of it, but I didn't realize that Black could have had a last move.

pompom, that is, in fact, my favorite stalemate. It's not exactly on topic, but funny nonetheless.

This topic is very interesting

Mate in 1 for white and black.  There are different options to mate.

Interesting idea. Obviously there are plenty of similar variations on that theme. For example, the following position satisfies the conditions in the first post.

Here's another one that I came up with.
