In this roundrobin https://online-go.com/tournament/31265 assuming I lose the game against hajnalmt, then 3 people would have the same number of points. How will the winner be decided? Even considering hajnalmt getting unfortunately disqualified due to time out, there are still two players left.
I think the standard tiebreak used in round robin (in a two way tie) is to use the head to head match. So, in this case, you would win because you won against exotour39 already. Not sure if this is the OGS implementation, or if there are any other tiebreak methods though.
Ties are broken by whoever has the higher rank at the time. So in this case, you would win.
