Is no resigning and dont accept rematch a disrespect?

I agree with several above regarding rematches.
I do however find folk who don't resign in obviously losing scenarios annoying. What do two mid-rated players gain by going through the motions of a KQ vs K checkmate? In these cases I will block the opponent after the checkmate so I don't have to play them again.

Yes, not giving a rematch (SPECIALLY IF YOU PLAYED WITH WHITE) in short time controls is usually considered to be rude. Also not resigning in a dead lost position (for the players rating) is also rude. Perfectly legal but annoying. Didn't block anyone because of not resigning, but did for those who only give a rematch when they win (which is also rude).
Also there should be added an aditional playing option which might be named whatever devs would like it to name (for instance SHOWDOWN CHESS or 1VS1 MODE) which forced each player to accept at least 12 rematches against the same player for bullet and super-blitz time controls, it would encourage more serious 1 0 scrammbles and avoid all the 1 game quitting which I find annoying.

There are a lot of lame people that play on chess servers like lichess (but I find it is less lame than on other pay sites), and when you sign up for a given time control, people can use every second unless the site recognizes they have abandoned your game.

Also, I generally accept rematches unless I genuinely have something else to do.

I think it is lame to "hit and run" in one game.

Lamest of all, though, is the person who aborts all games with black and will only play white pieces.

rules of the game do not require resign so if you liket to play to end no problem

People who whine about rematches are sad. Your opponent agreed on one game. It is silly to assume that he would play another.

I think people who do not resign in a lost position (remembering that I play 1900+ players, are not silly and know how to play chess) concludes that you are weak enough to they reverse the position.

This happens on all levels. Carlsen would insist on playing against ourselves with a queen down without any compensation. But he would resign IMMEDIATELY if his opponent is a 2800+. To be honest, they resign many moves before losing the queen ;). In Speed Chess Championship We see players resigning WITHOUT win on time ;) <-- respect!

With this, it is obvious that there is a certain disrespect, the opponent is saying: you are weak, I do not give any value to you, so I must continue.

Now about the rematch, we all know that this is a matter of education. Chess is much more than a sport, the players (those respectful) are interested in proving that they are the best players, so they create matches where it takes at least 12 games between the players giving the opponent chances to recover from a bad game. This was so much more evident in the early 20th century that even after the 12-games match the loser had the option of asking for a new match.

What's the idea? the idea is to be COMPLETELY convinced that you are superior (or inferior) to your opponent. A match like Carlsen x Karjakin does not convince anyone that Carlsen is better than Karjakin in long time controll matches.

To further analyze this idea, realize that players with a high rating (above 2700) 'will always' play a match, at least 3 games. They know it would be disrespectful to play only one game.

But 1800 ~ 2200 players are looking to score points and winning is the only goal. And they use the hit and run strategy.

It is to divert the subject to say that the player has no time to play anymore because he will immediately play another game against another opponent ;).

thinking....

Anyway, I think some feelings about that is because the opponent idea: I'm a WEAK player is correct! And a mix of 'I'm not weak, I can win that guy in more two or three games' and 'damm! he is right, i'm is too weak to win in next 10 games, no rematch make sense' make me very sad! BUT, one part on my SAD is disrespect from my opponent, the other, is my own psychologycal problems lol <-- may final conclusion

I get a lot out of it because of my style of play. When I play against players of high rating I become more attentive and leave them with a game difficult enough for them to feel that of every 3 matches they play with me will lose at least 1 and it is a bad deal!

You over analyze these things.

resigning: I lose very often if I am losing and sometimes wonder why the opponent does not. For a second. Then I know it his business to know why and none of mine. So just finish the game. Obviously Elo 2800 players behave differently. Then again otb blitz I seen IM to finish hopeless game. So in Blitz unless opponent is GM be prepared to finish him off.

As for second servings. I do not care if my opponent is better or worse than me. I do not even know even them. And analogs to 12 game matches? This is internet we can get more opponent we do not have to play same opponent we don't like to. As for who is better - thats what the rating is for.

Issue is: Contract was for one game. Shows bad manners to whine is someone respects the contract. Besides why you want to play this specific person? It is not like you would be short of opponents here. Obviously you are quite bit stronger than me so probably you have bit less but still plenty

Issue is: contract is for one game, but there are players that want a contract for more than one game. No one is saying that playing only one game is bad, but it would be nice to have an option to play a match. Playing against the same opponent makes sense if you want to play against their style or to repeat opening.

I often find that people who demand a rematch after a game become abusive in the second game, or especially if they win the second game. It's easier to just avoid that risk by not playing rematches.

If the person is friendly or we discuss the game afterwards, that's different. Then a rematch is saying, "That game was interesting. Let's do that again."

Because otherwise, in some ways, isn't demanding a rematch after a loss what's really disrespectful? It's saying, "I know you just beat me, but that doesn't count. This next game is the one that matters!"

If you insist on rematches after you lose, but not after wins or draws, consider exploring your own motivations before you declare the other person disrespectful.

When I invite someone to stay for one night in my house, I don't expect them to ask for another night and then be annoyed if I don't say "yes".

a reason you could not resign in a totally lost position is they could end up stalemating you
