Wesley So's rapid play has been outstanding in this year's Grand Chess Tour, but in Paris he wasn't as successful as in Leuven. He finished the rapid portion with a one point lead (a half point lead on traditional scoring, which comes to a full point here as the rapid games are weighted double compared to blitz games). He went 6-3 in the rapid round-robin for a score of 12 points, with Sergey Karjakin and Hikaru Nakamura a point behind.
In the blitz he started out well with a couple of draws and a win, but consecutive losses to Karjakin and Alexander Grischuk pushed him into third place. Karjakin got off to a fantastic start, drawing with Nakamura in the first round and then reeling off five straight wins. He cooled off a bit, losing in rounds 7 and 9 (sandwiching another win in round 8), but it was still good enough to finish the day with 17.5/27, a point in front of Nakamura and a further half a point ahead of So. Maxime Vachier-Lagrave is another point behind So (he has 15 points), and Levon Aronian rounds out the top 5 with the only other plus score; he has 14 points.
The action concludes tomorrow, and starts two hours earlier than usual, at 12 noon local time in Paris (6 a.m. ET).
