Coming out of a quiet Italian Game against Shankland, Caruana built up a powerful kingside attack and looked to be on the way to victory as he found a way to win a queen for a rook and minor piece. But a serious mistake by the top seed allowed Shankland enough counterplay to equalize, forcing Caruana to give up a rook and draw the game by perpetual

In the meantime Niemann was doing well on the clock and just slightly worse on the board against Robson, but an inexplicable blunder by Hans left his queen trapped in a single move, which Robson immediately spotted to win the game.

Other results were drawn, with the exception of Mishra-Sevian, which saw the young prodigy gain an extra pawn and convert a bishop vs. knight endgame with precise technique.

2023 U.S. Women’s Championship
It seemed like today would be the day that Yip’s winning streak would come to an end, as she got into serious trouble against Pourkashiyan, who sacrificed an exchange and had Yip’s king on the ropes. But several blunders in mutual time-trouble allowed Yip to escape and even overturn the initiative, as she turned the tables to win her fourth straight game.

Having a much less dramatic route to victory was co-leader Tokhirjonova, who smoothly outplayed Zatonskih on the Black side of a Queen’s Gambit Declined, as her pieces infiltrated White’s position in the middlegame, soon leading to decisive material gains.
