Its almost yours for sure. If Guodong lose tomorrow then most likely you are going to get another 2 points. Even if Guodong win, I still doubt that he will get 2 centuries to top over Zhao Xintong
I think even theoretically. Ozymandias_DZ has a worse 2nd tiebreaker, Strongkored can't get on equal points and the rest of the chasing pack is too far away.
The only way in which I lose is if Xiao gets 2 more centuries (likely) and in which I've made a mistake when checking the main tiebreaker against Ozymandias_DZ - but I think we have the same 8 players. Too lazy now to recheck, still hope Xiao won't make me do it.
