This was not your typical weekend Swiss: in the last three rounds, Mesgen had to beat current Illinois State Champion GM Dmitry Gurevich and four-time U.S. Champion GM Alexander Shabalov, then draw Filipino GM Mark Paragua.
95-year-old Erik Karklins tied for second in the Expert section and gained an estimated 21 rating points, for a net gain of 85 points this decade.
10-year-old Warren Scholar Conrad Oberhaus won the Class B section with a perfect 5-0 score and is now an A player! Warren Scholar James Wei (age 10) and grizzled veteran Zachary Holecek (age 11 or 12?) scored 3½ in the Class A section: both gained a bucket of ELO.
Crosstable here! (USCF hasn't rated yet: I'll edit the post to add when it does.)
