There are resourses that can estimate your elo rating such as this one. Usually I need to solve some puzzles and the system will give me an estimation of my elo rating. Here I have a different thought: Can an online resource estimate my elo rating based on the games that I play?

For example, if I can upload the recent 100 games that I played under some standard time control, will there be a way to estimate my elo based on how I play? It seems feasible to me but I am not sure if such resource exists.

If, as part of that upload, you also supply the ratings of opponents in the same rating system (i.e. all FIDE or all lichess or all chess.com) for at least 5 of the games in which you score at least half a point, then yes. Of course the moves played would be irrelevant.

The point being that no rating system gives a measure of absolute playing strength. Every single rating system gives a measure of relative playing strength.

  • Thank you! I was hoping that the system can analyse the accuracy of my moves instead of my results. So even if I scored zero in all games, the system still can reasonably estimate my elo. – Zuriel May 5 at 21:12

    Remember that "Elo" is only a system for calculating a rating (and also the name of the person who invented the system...), and the only thing the rating is useful for is comparing your success to other players in a given pool of players. You can't "estimate your elo" based on the moves in a game because it's not an absolute benchmark of skills (like, "if you have this rating, then you have the following playing skills") - it is literally only useful to compare yourself against other players in a given pool of players. – patbarron May 5 at 22:02
  • @patbarron, see en.wikipedia.org/wiki/…, where the elos of some famous players before the invention of the elo system, say José Raúl Capablanca, were estimated. I doubt if José Raúl Capablanca has played against any player with an elo rating, yet there is a way to estimate José Raúl Capablanca's elo. – Zuriel May 10 at 23:54
