ranking while playing mulitple games
It certainly used to be based on when the game ends. I know from when I have done rated simuls that the points change at the end of the game isn't necessarily what it says it would be, due to other games finishing in the interim. It's been a while since I've done one, though.
I'm pretty sure it's when the game ends. After all, a game can go on for a year.
So you will want to use the option where winning gains you more points and losing loses you comparatively less. So if you're 1700 and you're losing against a 1900 and winning against a 1400, if you lose the losing game first, your rating drops by x points and then increases by a figure less than x, but if you win the winning game first, I think you stand to lose relatively more when you lose the losing game, because all things being equal, the rating difference is less with the losing game and so more points are at stake than in the other game.
I think this is so but I'm not sure.
Yes, that's definitely true all things being equal, although if you're a very infrequent player with a high Glicko rating deviation you may actually be best taking the win first and then the loss with a more "stabilised" rating. There's no exact answer.
Thanks for that. Now I better look up "Glicko rating deviation". The thing about this site .... you can learn something new every day, as they say!
In the event of winning two games, I imagine winning the higher rated one first is better.
For example, you are rated x and playing vs a rated x+0 and b rated x+400.
Winning against b would increase not only your rating but your glicko deviation, given that a win vs a +400 rated player is an unlikely event.
Winning against a would actually decrease your glicko deviation given that a win against an even rated player is expected.
The a higher glicko deviation puts more weight on win/losses on your actual rating.
Kind of weird, in my opinion it should be clear how much points are at stake at the start (maybe even showing per game)

I always play multiple chess games. Now i wonder is your potential rank loss or win determined at the start of the match or at the end?
In other words: should i resign a already lost match, when another winning match is coming to an end, so i end up with losing less ranking points, instead of first winning the match (rank increases in the mean time), then losing the already lost match with a higher rank.
