Shortest-proof-game challenge

It was always just bishops

#1022

Another one bites the dust. Now we just need to see a shortening of #982.

a puzzle but also a shorttest proof game. the shortest proof game is the current position. 

find the shortest proof game before move 1

correct

#1024
First attempt

#1024
Shorter and white to move

there is a 35-move game that n9531l1 posted

#1029

For some reason, no one has reported they are working on shortening the position https://www.chess.com/forum/view/more-puzzles/shortest-proof-game-challenge?page=49#comment-62641397 since YidingL1 gave up.  So for now, it stands as the longest shortest proof game posted in this thread, at 97 moves.

hi just testing

The position at the end of the game below was posted over five years ago in the Illegal Position thread. No coordinates were given and the OP meant for Black to be on the bottom and specified Black to move. The OP gave the wrong reason for the position being illegal. It's illegal because the white pawns haven't moved and Black doesn't have enough captures to get five pawns to the open file for rook promotions.

If White is on the bottom, the position is legal regardless of the side to move. I didn't spend too much time on this proof game. How short can you make it?

#1035

That's a major improvement. I predict no one will top it.

I've heard guys brag about their length, but tygxc gets the prize for shortness. Now all he needs to do is substantiate the honor by doing his thing on #982.

#1036

Shorter

My mistake. I should have predicted that no one else will top it.

#982
Shorter, but probably not shortest
Still long, but maybe not longest
