The Saint Louis Rapid and Blitz is now a two-horse race, as Magnus Carlsen and Wesley So have separated themselves from the rest of the field with a three point lead. After nine exhilarating blitz rounds, the World Champion leads the tournament, overtaking So by half a point. Ian Nepomniachti finished the day in third place, but expressed doubt in his chances of catching the leaders. He promised to play 1.b3 again tomorrow, an unusual opening with which he defeated Carlsen today. The tournament will conclude tomorrow after another full day of blitz, with the winner taking home the $50,000 prize.
