GM Wesley So obtained a slight advantage against world No. 2 GM Veselin Topalov of Bulgaria but settled for a draw in the eighth and penultimate round of the in the third Sinquefield Cup chess championship at the St. Louis Chess Clubb Scholastic Center in Missouri.
In a tournament he would rather forget, So failed to gain any headway in a locked-up position that requires an “incredible amount of precision to create even minor problems” and agreed to split the point with the higher-rated Topalov (ELO 2813).
“Despite the fact that So-Topalov played over 50 moves, it didn’t last long in regards to playing time,” wrote Alejandro Ramirez in his report for Chess Base.
“So kept lashing out his moves, and was even above two hours on the clock (more than he started with, due to the extra hour at move 40) at some point. Topalov held comfortably in the endgame.
Overall, So now has 2.5 points on one win, three draws and four losses.
The 21-year-old Filipino champion is three full points behind GM Levon Aronian of Armenia with only one round to play.
Aronian split the point with former world champion GM Viswanathan Anand of India to raise his score to 5.5 points.
Four players -- GMs Alexander Grischuk of Russia, Magnus Carlsen of Norway, Maxime Vachier-Lagrave of France and Anish Giri of the Netherlands -- share second to fifth places with 4.5 points.
So’s final-round opponent is GM Fabiano Caruana of the United States.
