How could you cheat? This is what the Lichess terms of service say about it:
Cheating. We define this as using any external assistance to
strengthen your knowledge and, or, calculation ability to gain an
unfair advantage over your opponent. Some examples would include
computer engine assistance, opening books (except for correspondence
games), ...

It's really hard to tell what a brilliancy is. For example, you might try to say that a brilliancy is a move that's much better than any other move on the board. Well, if you offer me a queen exchange and I play queen takes queen, you taking back my queen is probably a much better move than any alternative, but it's definitely not a brilliancy. So maybe a ...

"PhishMaster's Complete Guide To Improvement": What to study, and how.
Every player has times where they "plateau", and have trouble moving on, but they usually get past it eventually if they are continuing to study. Sometimes, it is a matter of patience.
Here is a set of comprehensive answers to questions I previously gave in various chunks, that are now ...

Like I find it easier to beat a 1900 player on lichess than a 1800 on chesscom which is insane!
Why is that insane? According to one site, an 1800 blitz rating on chess.com is about equivalent to a 1915 rating on lichess (based on people who answered their survey and have ratings on both sites.) So, your experience of the 1900 lichess player being easier to ...

Here's why computer analysis (on any platform) can not find brilliant moves.
They don't exist.
Now, I recognize that this seems very counter-intuitive, but bear with me. This has to do with the difference between how we (intuitively) view a chess game and how a computer (correctly) views a chess game.
When we look at a chess position, we subconsciously ...

Elo does not signify how strong of a player someone is.
Elo signifies how strong a player is in comparison to some community.
Assigning a numeric score to rank how strong someone is in chess would be very difficult to do. The way Elo works (and even the way it is designed) is simply to keep track of players in some group and make predictions about which ...

You are being compared to perfection
Your every move is being evaluated by a chess engine with super-human playing-strength. The default is to compare your performance to its own super-human performance. Since the engine always makes the move it itself has identified as the highest-valued, perforce it always makes the best move by definition. Hence you can ...

Leela works by performing an exceptionally sophisticated positional evaluation at a relatively shallow search depth, whereas most chess engines work by performing a simple evaluation at as deep a search as possible. In theory this should produce a more positional style of play, and it does seem to be an effective strategy versus today's best conventional ...

I'd like to start with this comment of yours:
"I fear that without this abusive online playing my abilities OTB will be damaged."
I know where you are coming from, because I've been there, too. I used to be ridiculously addicted to chess - and I wasn't even very good lol. Now it's a hobby, which is much more healthy.
I also know that fear you ...

The king does not cross b1 (only the rook does). It also does not end up standing on b1 following the castling. Hence, the quoted rule is not violated.

Unless you explicitly hard-code these endgames, or provide the computer with endgame tablebases, they will apply what they've always done throughout the game: search lines and return the static eval (which is basically the evaluation function of the engine, evaluated on the final position). The static eval isn't smart enough to realize that this game is a ...

First of all, lichess rarely bans players. What they usually do is flag their profile (usually for using chess computer assistance), remove their rating, and prevent them from p laying in tournaments and/or rating games. This is not a full ban.
To answer your question:
Lichess flags players for a variety of reasons, but (as mentioned above) they usually ...

If I understand correctly your x axis is the moves. Your script implied Anand and Prag were blundering every time they make a move,
Clearly you have a bug in your script. Stockfish engine always give you a score relative to the player making the move, NOT white. You need to multiply the score by minus one if it’s Black to move.
Please do this and you will ...

There is a lot more to this, and this is really not a great tactics problem as much as it is a continuing the attack problem. The difference is that with a tactic problem, you can see the result all the way to the end. Other positions, you have just a feel for it, and you know that you are probably winning, but you have to play what you can calculate, you ...

In a chess there's a 3-fold repetition rule, if the same position appears 3 times, a player can call a draw. Your opponent allowed a 3-fold repetition, hence, the game was drawn.
3k4/8/p1PK2p1/1p4P1/1P6/P7/8/8 w - - 11 57
Edit: clarifying in light of comments:
Note that the draw does not happen until claimed by a player, and since you didn't claim it, ...

No. After ...Bc8??, Ra8+ checks win for white.

It means how many half moves ahead stockfish looked from the current position. It doesn't mean it looked at all the moves possible to that extent thought, it trims what it analises, otherwise it would be unable to reach such depths, this means a mate in 10 for example may only be found when stockfish searches in greater depths. In general, greater depths ...

I'm going to assume you meant ...Qc7 instead of ...Qc6, since the latter move blunders the queen.
After 1...gxf6 2.Qg4+, Black has three moves:
1) 2...Kf8 loses the queen to 3.Nd7+.
2) 2...Kh7 leads to mate after 3.Bd3+ f5 4.Bxf5+ exf5 5.Qxf5+ Kh8 (5...Kg7 6.Qxf7+
Kh8 7.Ng6#) 6.Qf6+ Kg8 7.Qxf7+ Kh8 8.Ng6#.
3) 2...Kh8 is Black's best move. After 3.Nxf7+ ...

Lichess is definitely very good at avoiding false positivies and rectifying those false positives when they do occur.
Even though I don't have access to moderator tools on lichess, one can spot cheaters fairly easily. They usually have the following characteristics:
A "flat" time graph where all of their moves took about the same length of time - even ...

In case of 16.hxg3, Black plays 16...Qxg3+ when White has only two legal moves:
17.Kh1 Rf6 followed by 18...Rh6 is a quick checkmate.
17.Qg2 Qxe3+ and after the check is parried Black can already take back his piece with 18...Qxd3 (with already three extra pawns as a reward), or continue the attack with 18...Rf6. He's completely winning in both cases.

TL;DR: Unless your move was marked as "Mistake" or "Blunder" with the significant material loss, you should not worry much about that.
I don't mean you have to ignore everything that computer says, but there are different ways to play chess, and your way may be not as bad as computer thinks. Here are a few points you might want to keep in mind.

In Lichess, you have 2 separate features: computer analysis and endgame tablebases. Scores are always shown using the computer analysis feature, but at the endgame you can also see the tablebases features, available for 6-men endings I think. If you open this component, you will see each winning/drawing/losing move together with their DTZ (distance to ...

Lichess is good about false positives as far as I know. Unfortunately confirmed cheating in longer time controls is harder to catch because many people won't make engine moves every time. In general most good players will not play rapid online for this reason.

I agree with itub's comment. You don't neccessarily have to give up on playing online altogether, but ask yourself whether you just play on at times, game after game, like you're possessed.
Does chess become an obsession rather than recreation? Does this happen to you for all time controls?
In general, obsessive playing is more likely when playing blitz (...

Average centipawn loss is the difference of your move to the best computer move averaged over all moves.
Inaccuracies/Mistakes/blunders as defined per lichess are moves that are at least 0.5=50 centipawns / 1=100 centipawns / 3=300 centipawns worse than the suggested computer move.
This rule is not strictly enforced in situations where you have a clear ...

What prevents 2. Qe2, which would save the White Queen?
White's problem is the mating threats from the bishop battery and queen after Qc3. For instance:
[Title "lichess puzzle 61506"]
[FEN "rn2k3/1b1p1p1N/4pBrb/qp2P3/3P3P/pP1Q4/P4PP1/R2K1B1R b q - 2 19"]
1... Be4 2. Qe2 Qc3 3. Rb1 Qxd4+ 4. Ke1 Qc3+ 5. Kd1 Bxb1 6. Bg5 Rxg5 7. hxg5 Bxh7
and White is lots ...

There are plenty resources available. First of all, you may be interested in the Universal Chess Interface protocol. This is a text protocol that many engines use. A compiled list is available here.
The protocol specification is available for download here (last link on the page).
There is also a python implementation of the protocol.
Last but not least, ...

Even at 1700, the vast majority of your mistakes are going to be tactical errors...especially at the faster controls. The only way around that is to start studying and practicing.
There may be some people, who can benefit from online tactics, but am of the belief that they lend themselves toward the trainee being shallow, and often the answers are the ...

There is a game theory of why 1st round NFL drafts don't perform as well as expected. The reasoning is that the player had an above average couple of games and returned to his average performance. By the same logic, there are later round drafts who have stellar careers.
I'm not going to make a judgement based on three games, or even your archive on ...

Let's look at this from another perspective. Instead of assuming that the problem is just that the ratings at different sites mean different things, let's take that out of the equation. Let's look at the reasons that you could observe that opponents at your rating on one site play fewer mistakes than opponents at your rating on another site.
Your opponents ...
