Shortest-proof-game challenge

your trying to set up the 612 position not that game. its just a hint

5 for u

and 2 for u if you find a faster on i will give you another 2

black to move

looks headache inducing

Here is a shorter proof game

(#623) @EvinSung

Honestly I don't think this is possible, since there are just too many restrictions on pieces, the dark dishop, rook and king needs the b7 square to maneuver and swap positions of the king and bishap, but either the pawn will be pinned with Q on a7, p on b7, k on c7, or the queen blocks the b7 sqare at a8.

So, I don't think there is a way for black to triangulate, but here is my try:

The position was posted as a shortest proof game challenge, so we should assume that EvinSung has a proof game. If it really is illegal with Black to move, it doesn't belong in this thread with that stipulation.

You found a good proof game for the version without the stipulation, and others could try to find a shorter one.

Here is a proof, not yet shortened

But you ended with White to move, just like Hillosanation did in 49 moves. The stipulation requires ending with Black to move.

wait why not 3.a3??

i think that in the start there can be something like bf6 nh3 be5 ng1 added

and then side to move changes

Do you think that will work? All you need is the proof game.

idk

#629
My bad, I did not notice black to move and I even failed to properly read #626.
I think it is possible. White's last move should be Na7xc8. Black's previous move then was Rb8-c8.

#623
Here is a proof game with black to move, not yet shortened

2 for u

Now EvinSung should post his proof game so we'll know how much shortening to aim for.
