Wesley So Takes Solo Lead

In the eighth round of the US Chess Championship, Wesley So took a massive step toward the title by defeating his young compatriot Andy Woodward. The three-time national champion advanced to 6/8 points, pulling a full point clear of defending champion Fabiano Caruana, who was held to a draw by Sam Sevian. The tournament leaders are set to clash in what promises to be a decisive showdown in Monday's ninth round.

From the Ragozin to a Precise Pawn Endgame

The duel commenced with the Ragozin Variation of the Queen's Gambit Declined. Playing with the white pieces against the 16-year-old Woodward, So gradually simplified the position while demonstrating flawless clock management; after move 18, he still had 1 hour and 25 minutes remaining. Following a sequence of piece exchanges, the game transitioned from the middlegame into a pawn endgame that initially appeared objectively balanced, yet demanded utmost precision from Black.

Passed Pawn Breakthrough Decides the Duel

Following White's 33.Kc3, holding the balance became increasingly difficult for Black. Although 33...a6 was available to blunt White's plans, Woodward struggled to find the best defensive setup. Instead of 36...Kc6, playing ...h6 would have offered better practical chances. Once White played 37.h4, the move ...h6 was no longer viable due to the winning b5 break. After Woodward opted for 37...Kd6, So struck with the clinical sequence 38.c5! bxc5 39.b5!, securing an unstoppable passed pawn on the queenside to seal his fifth victory of the event.
