what happens if you faint during a chess game?

It didn't say how they scored the game!  Don't these writers have any sense of priorities?

(I suppose I could probably find it in an archive somewhere.)

what if, for example, someone tripped on their chair whilst getting up to get water, falling and breaking their arm. lets say he's...........Carlsen for effect. now, because he's so important, would the tournament continue, or would they postpone it due to his condition?

but...... he's CARLSEN

I guess the arbiter calls a doctor or something?

I don't know FIDE rules.  Under USCF rules, round times may be altered in the event of an emergency, as long as all participants are informed.

Section 16Q also allows the TD to interrupt the game for matters beyond the control of the players, so that would probably apply in the fainting, or other more morbid, scenarios as well.

So it would be up to the TD.  Presumably, any tourney where Carlsen is playing would be a tournament where his participation was part of the point of the tourney, so they would bend over backwards to accommodate him.  On the other hand, if he just showed up to play at the Chicago Open, and waiting for him meant a six hour delay for a bunch of people who paid a few hundred dollars to play, but have flights to catch and day jobs to tend to, they would go on withouht him.

When it comes down to it, a lot of these nitpicky rules that define every single situation are because USCF uses the exact same rules for K-1 scholastic tournaments as for major championships with 100,000 dollar prize pools.  If that much cash is on the line, it's important to make sure you can point to something in the rule book if something odd happens that might affect prize distribution.

And then, it just becomes part of the culture.  You play by these incredible nitpicks, just because that's the way it's done.

Assuming the game is in progress, i.e. each player has made at least one move, I think the only option is to let the player's clock run until their time expires, then score the game as a loss and rate the game accordingly.  As for why the game gets rated, it's because there are highly rating-conscious players out there who wouldn't hesitate to fake a health issue if it allowed them to avoid losing rating points.  It's shocking sometimes how seriously some players take their ratings.

Now, I think an interesting question would be how to score the game if you are somehow responsible for your opponent's problem.  For example, let's say you are Spiderman and you get summoned in the middle of the game for a global crisis.  So you leave the playing hall and save the world, but in your haste to exit you accidentally kill your opponent.  Do you still get the win?  Or, to make this even more problematic, what if your opponent was a Black teenager?  Tournament directors, how would you handle this?    

so basically if carlsen, like, breaks his arm the tournament would be cancelled/ postponed? wow. i mean, it makes sense that they would do that, but what about the other players?
