Find the shortest proof game for this position. This is a legal position as White captured a Black piece on c8 and promoted to induce a discovered check and mate.

First try, probably much too long.

Nice try. I did some maneuvering from your game and found this.

That looks good. I was about to ask you what a good number would be to shoot for.

Cool

I am reposting shoopi's position from #203 since it was never attempted. After it appeared, there were no more posts in this thread for more than eight years.

I'll be on it! :-)

33.0 moves is my first try.

That seems like a very good result. I wondered why shoopi hadn't put the white king on e5. That would have looked better to me, but it would probably be shorter.

Thanks. Making it longer makes it more challenging to find the longest shortet. It's funnier that way!

Now I'm at 28.5

If you keep improving at that rate, in two more hours you'll be down to 11 moves.

I've just barely hammered it down to 28.0 by cutting out a queen move. I'm almost certain that this may be optimal.

I think you're probably right about that. I'm sorry the original cast of characters at the beginning of this thread aren't still around.
