US Chess Championships 2015
Mark Crowther - Monday 13th April 2015
The US Chess Championships took place in St Louis 1st to 12th April 2015.Players men: Hikaru Nakamura, Wesley So, Ray Robson, Gata Kamsky, Alexander Onischuk, Daniel Naroditsky, Sam Shankland, Varuzhan Akobian, Timur Gareev, Kayden Troff, Sam Sevian and Conrad Holt. The women's event has Irina Krush, Tatev Abrahamyan, Anna Sharevich etc. Play starts 1pm local time 7pm BST. Top seeds Hikaru Nakamura and Irina Krush took the men's and women's title. Wesley So was controversially defaulted a game after taking inspirational notes to his game vs Var Akobian after warnings about similar messages on his score sheets. I also wonder if we'll look back at this event as Sam Sevian's debut, the 14 year old finished on 50% after winning on time in a position he was only trying to save against Conrad Holt. Games and results.
