As far as I can tell from playing tournament games, running out of time in a tournament game gives you a karma penalty, but no ELO penalty. Is this correct? Is this by design? Because if so, it is a VERY FLAWED SYSTEM, and VERY UNFAIR. Because it means that if you are definitely going to lose a tournament game (because your opponent has just made a move after which every response is a losing move), then you can avoid ELO loss by simply not playing the rest of the game. True, you lose some reputation but if you play a lot, you can gain that back pretty quickly. On the other hand, if you stand to lose a lot of ELO by winning a game, you can conveniently avoid losing it in this fashion.
I would have thought that nobody would do this (it is pretty unsporting!) but sadly I've been cheated out of ELO gain in this way several times in the last few weeks!
If I remember correctly, before the reputation system was changed, one *did* lose ELO for running out of time, and this phenomenon is new since the karma system was put in place. But maybe I am wrong about that. In any case, please fix this problem. Thanks!
