To whomever remebers that game with 6 pawns on a file for each side, I indenpently found a game for it in 33.5 moves recently, altough the kings are in different positions. It’s still nice though. It is optimal for just the goal if getting sextupled pawns  for each side

Also see it here in my question on Puzzling Stack Exchange: https://puzzling.stackexchange.com/questions

Yes, I know that that that solution already exists, but I just want to be proud of myself for finding that myself before checking the forums!

#1581-Not legal as there are no missing black pieces to have made the white pawns on the e-file doubled.

#1579-Not legal as there is no black king on the board.

#1578-Easily legal. Here’s the quickest way that I found reach that position-moves.

King simultaneously checked by Bishop and Rook, no possible discovered/double check, both positions illegal.

If blue to move then yes (blue would be in checkmate), otherwise I don't think so.

My bad, didnt see en passant. 

First pos illegal.

        Black king has to get to first rank before en passant. For an en passant to happen, Wpawn on b2 has to move to b4. With pawns on b2, c2, f2, and g2, BKing can't go to first rank.

Second pos legal. BPawn instead of Wpawn on c2, BKing can go to first rank.
