Game 64 uploaded back to lichess
lichess analysis always ends in a draw if you take its suggested moves. Does show some mistakes chess.com 10 made. However, if you make your own moves, you can still win if you have an advantage. Chess.com is more fun to play against. I think they both use Stockfish 8 in game mode, Stockfish 10 for analysis. Beating Stockfish 8 is still good as it is rated 2600. I notice there is some difference style. Chess.com picks different openings to play than lichess. However, I see GMs making some pretty bad mistakes lately. And in rapid chess, they can't do much calculation. So playing mostly by intuition and memory of past games.
