Position after 88. Kf5-f6
The sorrows of reigning U.S. Women’s Champ 于润荷 (Jennifer Yú) continue. In fact, she edged the abyss even in her game against Cervantes Landeiro, who repeatedly missed a technical endgame win, eventually allowing her opponent to save herself after 133 moves and over 6 hours.
The diagram represents the position previous to Black’s 88th move, when Cervantes Landeiro let slip her last chance of victory: 88. ... Rd5? The right move was 88. ... Nf3! with the obvious point of 89. Rxf3 Rf8+ or 89. Ke7 Rd3! winning in all cases.
89. Rg3! Once the g-Pawn falls, White’ll be through the day, whatever time it takes.
89. ... Rf5+ 90. Kg6 Rf3 91. Rxg5 Rxh3. With a theoretical draw. It just takes a while for Cervantes Landeiro to accept it.
