This is "old news", as the well-known oxymoron has it, and as the final pairing was announced here earlier it's likely that any readers who were interested then already know how things turned out. Nevertheless, for the sake of completeness: the St. Louis Arch Bishops won the inaugural PRO Chess League rapid tournament (15 minutes/game, plus a two second increment added after every move), a team event that stretched from early January through the end of March. The team was led by Wesley So, and in the final they defeated the Norway Gnomes, led by Magnus Carlsen.
Both So and Carlsen had enormous scores over the course of the season, and both were 3-0 leading into their head-to-head matchup in the final round of the team match. (Each team has four active players, and each player faces every member of the opposing squad.) Carlsen won that game - with the black pieces, at that! - but as St. Louis had already clinched overall victory So may have been a little less circumspect than normal. Even if that's true, however, it was a nice feather in Carlsen's cap to remind the world's hottest player who's boss.
