  Since mate is evaluated as a [finite centipawn loss](https://chess.stackexchange.com/q/22087/2785), all games have a finite average centipawn loss. I stumbled upon [this Reddit r/chess thread](https://www.reddit.com/r/chess/comments/mm8j00/my_friend_and_i_tried_to_get_the_highest_possible/) where [this game](https://lichess.org/Q08G2qqd#1) has an average centipawn loss of 1971 vs. 1981, but maybe it's possible to achieve a greater average centipawn loss.
  
  **Question**: What's the theoretical worst average centipawn loss on LiChess?
  
  Here I'm not interested in chess variants.
  
  I imported [this game](https://lichess.org/UFHBl9ys) (adapted from the above) which gives an average centipawn loss of 1982 vs. 1988; here LiChess evaluated to move 150 (unlike the above game, where LiChess only evaluated to move 100 (although [it's still slightly better (1972 vs. 1982)](https://lichess.org/tLgqqIv6) when evaluated to 100 moves, since the queen is hanging on the 3rd ply)).
