St. Louis: Nakamura and Robson prevail in whirlwind final

Both the native GMs led after the six classical games. Hikaru Nakamura went on to defeat Ukrainian FIDE ex-world champion Ruslan Ponomariov by 3-1 in the rapids, while Ray Robson held Ben Feingold 2-2 to maintain his two-point overall lead. The rapid chess phase was interrupted by tornado warnings, which sent the players into the basement.
