Wesley So scored a crucial victory in the first classical game of the open Grand Final, defeating Levon Aronian to take the lead in the match. The encounter arose from an Italian Opening that quickly became uncomfortable for Aronian, who gradually lost the initiative as So began to build pressure.
After Aronian mishandled the position in the early middlegame, So seized the initiative and conducted a precise attack. By move 20 he had already obtained a considerable advantage, and a few moves later he emerged a full piece ahead, after which the result was no longer in doubt. The victory was achieved in particularly smooth fashion, as Aronian was unable to generate counterplay.
The result places So in a great position to claim his first American Cup title. Aronian must now win the second classical game on demand to keep the match alive. Even if he manages to do so, the contest would move to blitz tiebreaks, and because Aronian reached the Grand Final via the Elimination Bracket, he would still need to win a further reset match to take the title.

The first classical game of the women's Grand Final between Carissa Yip and Alice Lee finished drawn after a complex struggle in which both players obtained promising chances at different stages of the game.
Yip emerged from the opening - in a setup with kings castled on opposite sides - with an advantage, and appeared close to obtaining a winning position. As the game progressed, however, Lee gradually improved her coordination and took over the initiative during the late middlegame, turning the tables and creating her own opportunities.
At one point, Lee missed a tactical continuation that could have decided the game immediately, as the move ...Nxg2 on move 38 would have left White in deep trouble. After this chance slipped away, the balance was eventually restored and the players agreed to a draw.
