What is considered to be the main rating on Chess.com?

In terms of main, I would say it is blitz for most players as that is most associated with online speed chess, although the other formats are also very popular

Rapid does tend to have higher ratings because players have more time to think.

So does your opponent.

The rating adjustment is determined ONLY by wins/draws/losses, not by the quality of the moves.

"More time to think" should have zero effect on ratings.

Yeah, that's a common misconception. Rapid being higher has nothing to do with the time.

Well good to know then. The reason I believed so was because I have seen players with higher blitz than rapid perform worse at slower chess, and players better at slower chess have higher rapid than blitz, so that when a player that mainly focuses on rapid plays a mainly speed chess player in rapid, the player that mainly plays slower chess could have the advantage and play above his or her typical speed chess strength for being more suited to that time control than their opponent

The main thing is that rating isn't an absolute measure like how fast someone can run or how tall they are. Ratings measure you relatively... relative to others in the same playing population. And they don't measure the quality of your moves, only the end results (win, loss, or draw). To be more specific, they predict your future results based on your past results.

You might entertain the thought experiment of entering a club where only grandmasters are allowed to play. If everyone starts at 1500, then the best GMs would still be below 2000.

The range of skill will set the range of ratings in a population, but whether it will be 1000 to 3000 or -1000 to 1000 is up to the organization. The math doesn't care either way (and yes negative numbers would work fine).

Bottom line, Chess.com rapid is not the same as chess.com blitz. And of course different websites are different too. Lichess rapid is not the same as chess.com rapid.

They aren't beyond comparing though. If you look at enough people who have multiple ratings you can approximate a conversion such as chess.com blitz +200 = chess.com rapid (or whatever).

Correct.

If the rating system is Elo or Glicko (or something similar), and if the rating curves follow a normal (Gaussian) distribution, then a difference of 200 rating points predicts a 3-to-1 (or 75% to 25%) spread of results. For example, on average a 1200 player should score two wins and two draws (or perhaps three wins and a loss) in a four game match against a 1000 player.

... but the actual base value of the ratings are arbitrary. One chess site might start new players at 1200, while another site might start new players at 1500. Both rating systems will work fine... but the ratings will be independant and cannot be directly compared to each other. You might end up rated hundreds of points higher on one site than on the other.

You're assuming that every time 10,000 players are gathered together (a random number) that they will represent the same range of skill, and have the same distribution of skill, but that's not true.

llama47

I said you can get a rough estimate for a conversion across sites and/or time controls, which is true. No exact conversion exists of course, just approximations.

And percentile is just as subject to relativity e.g. if I'm in the top 10% here and top 50% somewhere else that doesn't tell you anything without knowing how good those two populations are.

Mostly people who are good at ____ rating want to whine and cry about how that rating is the best... and if they don't like their rating they'll whine and cry about how percentile is more important than rating. Whatever. I really don't care about their insecurities lol.

llama47

I'm sorry you can't tell the difference.

llama47

I'm on a chess site talking about chess stuff... what's the problem.

Most important is how many friends you have.

There are no main ratings...

Blitz and Bullet are really tough at low levels compared to rapid. But after 1800 Rapid starts getting tough, comparably.

The +200 is valid at 1100 blitz since that = 1300 Rapid. But 1850+ Rapid really isn't easy and things even out there.
