We need more levels of A.I. increasing by 100.

We need more levels of A.I. increasing by 100:
500,
600,
700,
800,
900,
1000,
1100,
1200,
1300,
1400,
1500,
1600,
1700,
1800,
1900,
2000,
2100,
2200,
2300,
2400,
2500,
2600,
2700,
2800,
2900,
3000.

Personally I need levels 2000 and increasing by 100, because I had won all before 2400 and did not 2500 and higher.

We need levels from 500 to let all people determine their level of chess.

To match my hidden power I need AI to be all the way up to 3300. I am not even starting games below 3000.

Probably this is the answer to what you are looking for. Plenty of good AI's to play here.

I need to practice with different levels of chess players. I would prefer A.I. on lichess, when the A.I. level counter will increase by 100 for actual for me levels.
The purpose is to beat the A.I., when it makes different types of mistakes according the A.I. level.
This practice, pattern, would be helpful for many people in the world.
There are many sites with such feature. But they are not so comfortable as it could be.
2700chess site has for paid content for level increasing over 2600 and higher to 3000 with step 100 and does not allow to save and analyze games.
As "lichess has got patron only financial support system", I think it could make the true the suggestion with near future.

Bots are not the decision, because Bot's power is controlled by Bot's owner.
There are some existing useful decisions as I mentioned (2700chess). lichess could could do in the same wave: A.I. only in correspondence chess.

Actually, the A.I. ratings are not accurate. Sometimes the >2000 rated A.I. s make a very obvious blunder

Everybody make errors, even very strong errors, but difference is in the frequency of making errors.
In the site chess.com present the ability to play with computer of levels increasing by 100 rating points less then 2300 rating points. They do not present required functional still. But I would like to see the functional here (in lichess), because here are no restrictions doing analysis, number of games and all the things.

Post #1 - Maybe all the way down to 200 (chess.com does it) for the "I literally just started playing chess" people out there.

@MathWizKid First beat ai 8 then talk for more.
