As far as I can calculate, 6 is the limit for the most number of pawns on a single file possible. Is 7 possible at all, ignoring promotion? I only took into account using the edge of the board, not the center, so I may be wrong. If I am right, what are some ways to make my composed game go quicker?
The composed game is below. It is 50.5 moves long.
