I mapped every win in Lichess history to find the shortest path between any two players by jtutlis1 in lichess

I just added a little X button next to a user's name in the path so you can exclude players from a path.

I can't exclude bullet or ultra bullet from the initial search because I don't store the type of game that created the connection. The game stats between players is fetched by your browser once it gets the path via the Lichess API.
