Specific toxic behaviours

Just stop already.

Why do you have any expectations that someone who is 1500 will know about opposite teaming? Bluntly, you can't do anything about other players, so why worry about it?

This sounds like a case of people not playing like you think is nice to play... but FFA is NOT A NICE GAME.  

None of your complaints actually break any rules.  

I suggest you play anonymously if you want to keep your score from being a game issue.

Congrats on making me look up the word "Schadenfreude"

I feel like I should add that I obviously get the frustration. Overall, my claim is that we should move away from "player expectations" and toward a framing that these things happen, and are just part of the game and not a huge issue.

You're GENERALLY right, but here, in this particular case, the guy is 1500 in BULLET, and has played thousands of games, and does know about the opposite coop. But anyway the point is not about the OC, but about the fact of having attacked in front ON PURPOSE. (Of course I do know that many LL players will attack in front, and I wouldn't have said anything if it were just someone, and not someone who does this to ME on purpose and systematically). 

WHO on Earth obliges you to read? You don't like, you don't read, you don't react, it's that simple.

Frog, EVERY day I play dozens of games, win some, lose a lot, etc. and sincerely don't care, I am here to get fun. You miss totally the point, it is NOT about losing, and I find all such behaviours utterly pathetic whomever they are addressed to, not necessarily to me.

@Indipendenza I think that many of the toxic behaviors you listed are fairly general toxic behaviors among online video game players and are not specific to 4PC FFA. For example, many people on Lichess time out or take as many pieces of mine as they can before timing out after I have put them in a losing position. As a student of psychology, I can say that such tendencies theoretically stem from ancient yet extant evolved tendencies we have to seek to establish a "dominant" reputation (a reputation that one has the capacity to discomfort others, which evolved to seek to confer social status from others due to fear). Everything I have read also suggests that such tendencies are not easily changed by external or moralizing forces. It may palliative to hear that my readings also suggest those who function from such motives tend to rewire their brains to be less effective at life pursuits in general (how many "great" people act in these toxic manners?) In other words, it's all a mind game to annoy you due to such annoyance having resulted in fear at the time such tendencies evolved. But you don't have to worry because ultimately, such tendencies seem self destructive, although those with such tendencies will likely do everything in their power to have you think otherwise.

Quite interesting, thank you! I'll think more about that.

My point was that it's bad for general well-being here...

There are fortunately PLENTY of players, including many top players (2600+) who never do something like that, and to play with them is a genuine pleasure, either one loses or wins.

It's online chess, this'll never be "civilized" like otb chess. That's just something you're going to have to learn to work with.

Frog, that's not true at all. I always welcome advice when it makes sense. I was reacting to the fully inappropriate, unconstructive and rude remark from someone who is not obliged to read, by any means.

Dude, this whole forum is practically you complaining about 1500 player's behavior. There's no reason for you to make a forum about this, and it's not a guarantee every single 1500 is going to see this. In fact, it seems like you have something against 1500 players who can play how they want to play, but no, you have the nerve to call them out like something's going to be done against them. Just stop with this stupid topic. I wished someone would just lock this already. 

VP, you definitely read badly, or maybe I expressed myself badly, I am sorry, English is not my native language...

This thread is NOT about the beginners or inexperienced players nor about kids, whereas I can quote (but won't) easily 30-40 players who are decent level (let's say above 2100 FFA) and who from time to time do that. I only mentioned above ONE case of a 1520 player who in fact is only that low in bullet, and who has played thousands of games. But who targets me every time we happen to play together. (No, don't suggest to block him, I block nobody).

(BTW I must confess that I also do ONE thing from the list, very seldom but sometimes, namely if there is one player who definitely plays badly IN THIS PARTICULAR GAME but is winning for some reason, in some rare cases I may either arrange to get mated on purpose by another player who clearly played better, in order to make him win, or to resign ad hoc before getting mated in order to prevent the leader from getting these 20, I made that yesterday at some point as the guy by no means deserved the victory, so I preferred to resign and thus to give the win to a player who clearly played much better).

"like something's going to be done against them" : certainly NOT. Not feasible as it is not against the rules. That was my point: there are things which are not illegal but are mere impoliteness. When a player for instance obliges 3 other persons to wait for 3 minutes ON PURPOSE rather than resigning, it's just rude.

YES, Gold, maybe around 5%: https://www.chess.com/clubs/forum/view/to-betray-too-early-means-3rd-place-in-95-of-cases

Indi, getting 20 pts, even if it means mating your opp, is absolutely worth it.

unless you can easliy mate one of your flanks.

I was two times betrayed by opposite and my opposites even won after that. Usually they lose after. For example, taking your opposite's queen is usually wrong. But mating him is usually right. Also sometimes I betrayed my opposite by not supporting him while my side-players were attacking him and spending too much forces for doing so. Also, why should I support my opposite if he is planning something idiotic? I would rather save my own forces for good defense and future attacks.

Obviously if the mate is inevitable taking it on your opp is definitely the best play but if it is optional then I disagree that it is absolutely worth it.
