hi. just curious about it. when my and my opponent new ratings are calculated after the end of a game, the original values considered are the ones when the game began or when it ended?

Rating changes are based on the ratings of the players the exact instant the game result is decided.

If it weren't this way, I could, as a 1200 player, challenge 50 1400s, getting 200+ points per win. Of course, the rating changes are adjusted as my rating increases.

thanks for the answer. never thought of it, but this totally makes sense.

 

I asked because once I was winning from a guy with a rating much bigger than mine and was really happy thinking that my victory was going to raise my rating a lot. however before the game ended he went on vacation and eventually the vacation days were spent and he started to lose all games by timeout. his rating droped so much that when I finally won by timeout our ratings were almost the same. anyway I think this is just a side effect that doesn't happen that often.
