It is not a question of ethics, but more about being courteous. Chess is a game where it is impossible to separate the joy of the game from the competitiveness/ego aspect so by declaring a forced win in N moves, you are effectively asking your opponent to resign immediately even though he hasn't seen the forced win yet owing to his lesser faculties/skill ...
Is it rude to ask my opponent to resign an online game when they have
a lost endgame?
Yes, it is rude, although you are in good company. In one Olympiad Victor Korchnoi is alleged to have asked his opponent - "Do you speak English?" When they said "Yes" he replied "Then please resign". I may be misquoting. He may not have said "please" :-)
Assuming you also have plenty of time on your clock, make a break: have a drink, or check your mail, or pay a visit to the bathroom, or grab a book (even if it's an openings book, it doesn't count at cheating in that position ;) ), or go verify if your baby hasn't hurt herself with that knife she was trying to grab when you were too busy calculating your ...
The behavior you describe is bad sportsmanship and goes against the policies of chess.com. See the chess.com fair play policy and this blog post about the new abuse report system which includes an option specifically for "poor sportsmanship / stalling in games".
I think the reason becomes more apparent when you consider why the rule is in place for OTB games - an opponent constantly moving their hands around the board and moving the pieces around can be very distracting while the other player is likely still trying to concentrate on the position.
By contrast, in online chess both players are using their own ...
Welcome to Chess Stack Exchange.
I believe you're doing well here. It is surely a checkmate. Probably the website isn't programmed that way to recognize that move. But, as per your question, this is clearly a checkmate that resembles the one-rook-mate pattern.
Brian Towers answered the question, but to help you understand why people don't resign, I recommend you watch this lecture by GM Finegold Blunders, with GM Ben Finegold. The gist of it is:
Never resign, and look for resources no matter how bad your position
is. And when you are winning, don't let your guard down.
Lichess has an option to play blindfolded if you have an account registered.
You have to activate the Speech Sound effect, in the upper right corner → Sound → Speech.
To enable writing coordinates(e.g. Nxe4) instead of moving pieces you can activate blindfold mode in your game display preferences.
Enjoy your games!
Chess.com's site rules have the following to say:
You can NEVER use chess programs (Chessmaster, Fritz, etc) to analyze current ongoing games unless specifically permitted (such as a computer tournament, etc). The only type of computer assistance allowed is games databases for opening lines in Turn-based Chess and Vote Chess. [...]
So it boils down to ...
It's always rude to ask your opponent to resign. They should resign of their own accord once they're convinced that you're overwhelmingly likely to win the game. In my case, that always meant you'd have to convince me that you knew how to play the endgame in question and that both of us knew how you would win it.
If your opponent hasn't resigned yet, it ...
I agree that it would break the FIDE rules against note taking, but this is not a FIDE tournament; it is online blitz on Lichess, so FIDE rules need not apply. You'd have to look at the Lichess terms of service instead. They say
Cheating. We define this as using any external assistance to strengthen your knowledge and, or, calculation ability to gain ...
That's called a mouse-slip, and it's part of playing online. Watch some of Carlsen's online play (e.g. https://www.youtube.com/watch?v=SJlOlufG-JM) and you'll see even he mouse-slips on occasion. Common etiquette seems to be to continue playing out the game and try to be more precise next time.
Draw with insufficient material is covered in article 9.6:
The game is drawn when a position is reached from which a checkmate cannot occur by any possible series of legal moves, even with the most unskilled play.
With a given material, it is possible to construct a checkmate (assuming your cooperation or horrible blunders), so it is not a draw.
Engines have no concept of natural moves and they have no fear. An engine will play for the most advantage, not for the most manageable advantage, even if it allows a fierce attack, because it sees that the attack does not work, while a human would probably prevent an attack and settle with a smaller, but practical advantage.
"Randomly" picking ...
Upgraded all your pawns to knights
Your king is at Ka8
Your knights surround your king, so at Nb8, Na7 and Nb7
Opposition knight is at Nc7# - checkmate!
So it is indeed possible to lose, thus not a draw.
Just to offer a different answer:
No. No takebacks, no draw offers. In short time controls this is part of the game. It's the same as a blunder under pressure. I pressured the opponent on either time or position, and the person cracked and made a mistake.
Or your other example, of moving the king instead of castling in the beginning: That's what one get ...
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
Imagine a variation of chess without the rules about check and checkmate, where a player wins simply when he captures his opponent's king. In this variation, Kxd5 loses the game to exd5.
Turns out, that's more or less how real chess works. The objective is to capture the opponent's king. If your king is under attack, you must deal with that threat. If there'...
Honestly it's rude to ask your opponent to resign in any position. The one exception may be them deliberately letting their clock run to 0 in a completely lost position, but in this case they're being deliberately malicious and you can't really hope to reason with them.
Even though you're absolutely justified in thinking your opponent should resign, that ...
Yes, resigning a clearly lost game is indeed considered good behaviour. Sometimes not resigning is considered unsportsmanlike!
It makes no difference on the result of the game whether you resign, are checkmated, or lose on time - a loss is a loss. In any rating system I've ever heard of, the method of losing doesn't make a difference.
It's just that people ...
The sidebar says "1. Qe7# (1. Qc8#) (1. Qb8#)".
In case you're not yet familiar with chess notation, this means:
1. (White's move number 1)
Q (the Queen)
e7 (moves to space E7)
# (and checkmates.)
After that, your move "(1. Qc8#)" is highlighted in red, indicating it was not one of the answers they were looking for. But note that it is ...
I followed @itub's suggestion and filed a report against the particular user. Here's the answer I got from Chess.com support:

Most chess sites use some variant of the Elo rating system
If you have a much higher rating than your opponent, the expectation is that you will win. So if you do win, then we haven't gained that much information, so the change in rating for both you and your opponent will be small. If your opponent wins, there will be a much larger change in rating as ...
The Encyclopedia of Chess Openings (or ECO) is a classification system for the opening moves in chess.
Instead of the traditional names for the openings, ECO has developed a coding system that has also been adopted by other chess publications. There are five main categories, "A" to "E", each of which is divided into 100 subcategories.
Here is more info and ...
If we remove the component of flawed, human players from the equation and consider just the game of chess itself as it is spelled out by the rules, then chess is purely a game of skill with no room for chance. That is, it is in principle possible for there to be a perfect chess player that plays optimally against every possible move sequence by an opponent, ...
They may have made a fatal mistake and think that in another game they can win.
It happens sometimes. You could make a mistake, or miss a mating pattern, and suddenly you've lost the game although you thought you were in the lead. In this case, many people may ask for a rematch because they think that they should have won and want to redeem themselves. If ...
In general, less common openings tend to give weaker opponents issues, since they have yet to properly grasp many fundamental ideas of opening play and middlegame strategy, and if they don't know the concrete lines they may very well end up completely lost from a nonstandard opening position.
But a nonstandard opening doesn't make you into a stronger player ...
Those are just the rules of the game. You could absolutely try to make the case that moving into check in such a situation should be legal, but playing by those rules wouldn't be chess anymore (it would be some variant).
You could also ask why stalemate is a draw and not a win, even though the latter result would make more sense in a real battle. These are ...
