As a teenager I had a chess lesson with Ben Finegold and I practiced this puzzle for weeks on a physical board.

He also mentioned this riddle off hand which I had a ton of fun solving. https://fivethirtyeight.com/features/how-about-a-nice-game-o...

That is fun! It's interesting, the solution is presented here[1], but I'm pretty sure it's wrong (off by 19) due to not taking into account the possibility for the pawn to move two squares on its first move.

That post says,

> Note: If you counted the pawn moving forward two squares with its initial move as distinct from its moving two individual squares, then there are 160 paths. Feeling generous, I gave full credit for either approach.

I guess I didn't read far enough. Seems pretty obvious you'd need to count that as a separate path, to me the 141 answer is plain incorrect.
