Ties are resolved the way it is described in the rules.
In the email you received, even if you're under the tied player, if there is a "3." in front of your nickname, then you are 3rd as well.
Please note that even if you are tied, your ELO will evolve differently, regarding your previous ELO ranking.
if the game ranking is :
Then the ELO evolution is the sum of the 6 following oppositions :
- login1 beats login2
- login1 beats login3
- login1 beats you
- login2 beats login3
- login2 beats you
- login3 and you are tied. if login3 had an inferior ELO, then it is normal if he loses less ELO than you. You had to be better (regarding your ELO) so you deserve to lose more ELO points. This is te basic principle of ELO ranking !
