Closing my account because of how many BAD SPORTSMEN there are on this site!!"

I think I need to put a fictional character too. Can’t think of any.

Isn't this situation different from OP? To me a mouse slip is very different than a premove. Mouse slip means the player didn't intend to move the piece there, but a premove does

No because after Nxg4 I did not intent to move the queen to h6, but anyway, I said I was going to go and get some food, which is why I just made the premove because Kh4 was most natural although it led to mate, the knight capture also led to mate and I calculated all variations to mate.

The reason I premoved actually is because I just thought he'd go Kh4, as I said I went to go to get some food and I actually premoved because I didn't want to keep him waiting a move or two before checkmate, so I actually had good intentions with the thoughts and feelings of my opponent in mind, which is also why I snapped so hard and completely lost my temper when my opponent just completely ignored me and claimed the game when it all originally stemmed from me trying to be polite in good nature. 

Well, you are right. But I still think the OP’s opponent is wrong. The OP won the against his opponent in chess, but didn’t win in the game. What I mean is that, he won with more tactics and strategies, but he didn’t won the game because of the premove. I mean if it was OTB he would have won. Also, one of chess.com rules is to forgive and be kind. For my point of view, his opponent wasn’t following this rules. 

Hallelujah

Well, I mean, your opponent doesn’t have to resign. You still initiated the premove, so if goes wrong, that’s your fault. And that along with the fact that you stalled out the clock, no matter what your reason for doing so may be, still makes you wrong in my eyes.

that is true tho

Chess is a gentleman's game. The superior man of mind wins. But, by promoting 5 knights and delaying an inevitable checkmate, you're really just taunting your opponent, and it shows bad sportsmanship. 

the first opinion is subjective as most people now dont really consider chess a genteman game given the toxic behavior, rages, and awesome bullet moments of our generations youth players but again some still do consider chess that so nothing against that. however, players who dont resign and the player chooses to taunt its not bad sportsmanship as its up to the opponent to keep going or not and if he wants to get punished more then he keeps moving

Is it bad sportsmanship when you make your pawns promote to queen and don’t checkmate your opponent fast even if you can? Also is it bad sportsmanship to get stalemated after those pawns promote, and then the player who promoted the pawns says “We should play another game and you should resign because I should have won this”?

who knows, sometimes its worth being taunted as you might even end up with a draw lol

     You blundered away the game by making a bad pre-move, got upset when your opponent wouldn't resign when they were winning, pouted for 12 minutes until you lost on time, and started this forum to whine about how terribly you were treated when everything that happened was your own fault. If you actually close your account the benefit will be one less bad sportsman on chess.com.

I've already explained the bad sportsmanship you simpleton. I also made those premoves because I didn't want to keep my opponent waiting 2 moves before checkmate which was actually quite thoughtful of me and I snapped because the curtsey was completely thrown in my face.

That made me smile. You should write more funny stories!

Someone premoved against me the other week and took a knight that I'd just moved away! So I went a piece up. You should not need to premove, especially at rapid. Some people are stupid!

I agree OP played better. If I was the opponent I would consider it a loss but that doesn't change what actually happened. He still premoved when he had plenty of time on the clock and it was a bad premove that cost him the game. And yea I totally agree that the story would be different if it was OTB but at the end of the day it was online not OTB. If I were OP I would just take this as a lesson to be careful when premoving and I wouldn't close the account

I don't understand this. If someone promotes to 5 knights, (or 5 of anything or doesn't promote at all) I don't understand how that's bad sportsmanship. The position on the board doesn't care what someone promotes to. Only the two people playing care. 

As someone else said, if the move is legal, it can't be bad sportsmanship. And, of course, there is no such thing as "inevitable checkmate". I think the OP proved that beyond a reasonable doubt. 

The reasons someone might want to promote to 5 knights is absolutely none of the opponents business. Maybe they want to practice their knight skills, maybe they want to intentionally  get into a complicated position to test their calculating. Maybe they wanted to burn time so they could practice their time pressure skills. Doesn't matter. The opponents job is to try to win (or draw) with 5 new knights on the board. 

I think people forget chess is a game, with sometimes unpredictable outcomes. So if an opponent promotes 5 knights, use that opportunity to do something unique or something you haven't done before. 

But still, don’t you think the opponent should forgive the OP? I mean the opponent should have thought that he lost the chess part. He should have lost his rating . His opponent should have forgive him too.

     Repeatedly whining that an opponent took advantage of your blunder is courtesy? And why should I believe your story? If you were truthful, you would have closed your account as you claimed you were doing and wouldn't be here to read and complain about these comments.

I suggest you don't make comments on any public forums anywhere anymore because you clearly you lack research but not opinions. Everything you've asked me has already been answered.
