It was another round with all decisive games as tournament leader GM Andrew Hong lost a complex Winawer to top seed GM Abhimanyu Mishra, who at a critical moment sacrificed an exchange for long-term positional compensation:
Hong-Mishra: 19…Nfxd4!? led to a chaotic position after 20.cxd4 Qxd2 21.Nf7, which eventually turned Mishra's way. | 0-1, 72 moves

The win allowed Mishra to overtake the lead with 3.0/4, but he was soon caught by Jacobson, who won a close rook endgame against Xu, as well as IM Arthur Guo, who won his third straight game in the tournament, defeating IM Justin Wang.
Wang-Guo: After 27…Nd3, Black had an overwhelming strategic advantage. | 0-1, 48 moves

U.S. Girls’ Junior Championship
The key matchup between the leaders Lee-Tang featured a Stonewall structure, with Lee managing to trade down into an advantageous endgame and begin putting pressure on both sides of the board. Tang wasn’t able to successfully defend and ended up giving up a pawn, after which Lee had a clear route to victory.
Lee-Tang: 37.Rxe8+! ended the game tactically, as after 37...Kxe8 38.Rb8+ White will trade rooks and end up winning the rook on h3.
