Ruifeng Li was able to keep his tenuous lead over the field at the 117th Annual US Open after a long and grueling round 7. Li found himself down a pawn in a rook plus pawn ending against GM Joel Benjamin but was able to hold the position and his half-point advantage in the standings. Following just behind him are GMs Illia Nyzhnyk, Aleksandr Lenderman, Joel Benjamin, and Melikset Khachiyan as well as IMs John Daniel Bryant and Zurab Javakhadze, who all sit at 6.0/7. All sections have finally merged and the relaxed schedule will feature only one round per day through the end of the tournament. The remaining two rounds will start at 7 p.m. EST today (Saturday, August 6) and 3 p.m. EST tomorrow (Sunday, August 7th).

It is odd to think that the culmination of a game where black relinquished his white square bishop early in the opening will result in a devastating attack by black on the white squares, but this exchange sacrifice is both thematic and instructive. The bishop was the only piece keeping the enemy queen and knight at bay. Now, both have direct attacking access to the key squares near the white king.} 22.
