Back and forth it goes...Magnus Carlsen is now in the lead of the St. Louis Rapid & Blitz, though just half a point ahead of Wesley So. So played reasonably well on the day, but didn't make the most of his chances. More importantly, he didn't always push very hard to make the most of his chances. Carlsen, by contrast, fought to the last breath throughout, and while he had a colossal amount of luck on the day, it's also true that he put himself in a position to get that good luck, and has a narrow lead as a result.
Nine games remain today (Saturday) - a final round-robin - and the winner will be crowned. The chase pack is probably too far behind, so barring a quasi-miracle, it's going to be Carlsen (yet again) or So.
