*LICHESS.ORG🆚CHESS.COM. The classical debate. Which one do you think offers more support? *

I don't know where you came up with your numbers but Chess.com had more than 500,000 two years ago.

Yes

Yes

chess.com the best

If Proctor is rolled out for everyone, then chess.com will provide the best platform to play online chess whilst combatting cheating.

Not that a player using proctor can't cheat, but they'd do so in front of a camera where everyone can see, i.e. Mr FishUser is sitting in front of his computer whilst on another device is typing the moves into Stockfish - now it will be in full view of the cameras.

And yes I'm sure the very small minority will find a way anyway, just like it has been known in OTB chess. Something that vibrates moves to their feet etc. But that will be a very tiny minority. And if they really do keep winning, you could make them go "up" a level and be fully hybrid (play with arbiters present).

lichess wins in its opening analysis database where you can see games from lots of master games as well as online games to see what moves were played with various frequencies. That is very good opening preparation for what you are likely to come up against. Maybe it will just stay that way, and so those who want to prepare openings will go to lichess, and those who want to play in a cheat-free environment will use chess.com with Proctor. There is room for more than one chess resource.

Like chess.com, lichess has a cheat detection team that acts on reports and then determines if a player is cheating based on more than accuracy, but including move times and other behaviours. They can also detect where it is likely a player cheated only in a period of a game, i.e. between moves 10 and 18.

Interestingly, when you look at "insights" on here most players make their most inaccuracies during the middle-game, so a player who uses analysis mostly during that period would clearly show up as against the norm.

Lichess, I think. Chess.com have changed daily lessons to weekly lessons, and many locked feature, but chess.com has multiple bots

Constructive debate is good, especially where users think lichess is better, as that may help get chess.com to improve in those areas. I can tell you a few other players where lichess is better:

• The lobby. In chess.com it doesn't exist. You make a seek in an unusual time control and nobody sees it, so you never get paired. In lichess you make a seek in an unusual time control and it shows up in the lobby. Someone looking at the lobby may click on it and you'll get paired. 5+8 is common time control to see in the lobby, by the way, and often in variants. (On chess.com variants are now all moving to their own section, and in variants there is a lobby. Try getting matched in chess960 through playing a 15|10 time control. It just won't happen as nobody will see your challenge). There is plenty of room on the screen for the lobby as there is no need to display a chessboard unless you're setting up OBS for the first time to know where the board is going to be.
• As I mentioned in a different topic, to post in a forum on lichess you must solve a mate-in-one puzzle. That keeps away the spammers.
• Watching chess is generally much easier on lichess than on chess.com albeit even there one should be able to filter by time control and not just blitz/rapid/classical. And I think 10|0 where both players have berserked may even still be classified as "rapid" there. By the way, I don't like the berserk feature in arenas so I don't see that as an advantage there, but I guess many will.
• lichess has a "simultaneous" feature. Would be good for streamers to be able to host a simul to play their viewers in a longer time control, rather than putting them in a queue to play lots of short time-control blitz games. And you can start all the games "from position" which means Naroditsky could give all his opponents some material odds whereas a noob hosting a simul could give themselves some material odds against all their opponents.

The only two features where endgame.ai is better (that is Hans Niemann's new platform)

• endgame.ai supports delay as an alternative to increment. Neither chess.com nor lichess support that, although chess.com did use it in 4-player chess where the time control was 1~15. Not sure if it still is.
• endgame.ai has "guess the elo".

Because it can be a constructive way to show where they can improve?

I hope they read this, and take things on board in the aspects where people have said lichess is better, but as I said above, as long as there is still reason to use this site, I guess chess.com won't care if we use the other site as well for certain things, like more complex puzzles or opening analysis.

I have heard a number of people giving courses on chessable, a site owned by chess.com, refer to the lichess opening analysis database, and really it is something you can't ignore if you are going to learn an opening, as you are going to want to know what will be played against you and with what frequency. Anything played more than 20% of the time MUST be considered, and for more depth analysis I'd say anything played more than 5% of the time should not be completely ignored.

So let me give you an example. I'm planning to play Petrov against e4. So I'll respond e5. Firstly, to play Petrov my opponent must play Nf3 but what else might they play? I'm going to limit it to rapid and slower, and players rated 1600 and above, but depending on your level and what kind of speed you play, you might include other time controls and strengths.

Nf3 67%
Bc4 12% (Bishops opening)
f4 7% (King's Gambit)
d4 5% (Centre Game)
Nc3 4% (Vienna, but as Gotham Chess has a course on it, they may go up. Plus I think I've seen Hikaru play it)
The rest are all 1% or lower including d3 and Qh5 but we need to prepare quicker so we can't explore every line. Depending on your threshold you'll pick what to do against each or some of the above. I'm going to explore now Nf3 Nf6 though as I said we're going to play Petrov.
Incidentally Nf6 is 10% at this point so if the opponent is doing the same and it's inside their threshold they will prepare against it.
Nxe5 35%
Nc3 33%
Bc4 16%
d3 7%
d4 (Steinitz, probably more common at a higher level) 6%. (This move has the highest winning rate for white and the one I'd pick myself as white on this line)
So now go into those and learn a bit. Pick the move you like as look as it's reasonable. 
Against Nxe5 most players know the best response is d6 and some may "dare" to go for the unsound but trappy Stafford Gambit. If you're white and prefer Nxe5 to d4, prepare yourself against the Stafford so you don't get caught by the traps.
After d6 white will retreat with Nf3 83% of the time, but I should explore Nxf7 ?! (a bit like Alien gambit, sacrificing the knight there hoping for blunders later, and may be something worth exploring for blitz players as white who like excitement).

Ok, you see what I mean, how this is an extremely useful tool.

And what people will tell you is you can create a STUDY there with it.

I think it’s Chess.com because it has awards. Also it has more chess variants. Puzzles are a little bit more fun. Chess.com has many bots while Lichess has only Fairy Stockfish 1 to 8. But if you still like Lichess you can play on Lichess.

If the question is "Which offers more support" then probably lichess given that chess.com has decided to take its "support" over by AI Bots. See the pinned announcements at the top.

well, in lichess its free, that is good in one way, in chess.com u get a truckload of things to do but u have to pay. both r good in different ways

So i like and chess.com so lichess is free and in chess we need for the most thinks primium but in chess we can play with coach that is helpful (i am new in chess.com i don't know really what the talent of chess.com is)

lichess for bullet

I think lichess is better if you are just playing for fun/doing puzzles, but chess.com is better if you get a platinum membership and play games and thoroughly review them, along with studying openings and endgames. both are great sites but I prefer chess.com bc of my membership and the many tools I have access to.

Chess.com is 🧊
