I see that Alina Silich's SE was due to reaching a 25K final in Moscow last week, beating a couple of top 250 players on the way. 30 points from there has her at a huge new CH 546 on live rankings.
Maybe better I hadn't read that ( anyway other folk can share my "ah ..." ) but Maia has been on form too.
Maia 12-2 on the year, only JoKo has more wins.
Also, 5-2 against higher ranked opposition, no one has more upset wins (though Katie B is a perfect 4-0 against higher ranked players).
If she can keep this sort of form up, she can easily rise 300-350 places, and then we'll see.
