I forget the rough adjustment factors, but it is worth noting that lichess Elo is not the same as chess.com or FIDE. I think lichess is typically ~300 points above chess.com. This implies the model is around 2500 blitz vs humans. As blitz elo are often much higher than in classical time controls, 2500 elo on chess.com places it firmly in the 'good but not great' level. I am very curious to know whether the model suffers from the same eval problems vs the well known "anti-bot" openings that stockfish is susceptible to at limited search depths.

> I think lichess is typically ~300 points above chess.com. Yeah, no. They are two different rating systems (not ELO incidentally) with different curves, there isn't a fixed difference you can apply. At the high end of the scale lichess ratings are below, not above, chess.com ratings. E.g. Magnus Carlsen is 3131 blitz on lichess [0], 3294 blitz on chess.com [1]. This website [2] tries to translate between the sites, and figures that a 2925 lichess blitz rating (the closet on the website to the one reported in the paper of 2895) translates to 3000 chess.com.

  Cool, thanks for the information! I did not realize the curves were that different. 3000 definitely bumps it up but it would still be worse than the top humans. stockfish is better by a lot.
