Nakamura and Krush US and US Women Chess Champions

Grandmasters Hikaru Nakamura and Irina Krush have earned the 2015 U.S. and U.S. Women's Chess Championships, recording a career total of 11 national titles between the two.

GM Hikaru Nakamura and GM Irina Krush both sealed the deal in Sunday's final round of the U.S. Chess Championships, enshrining their names as 2015's king and queen of American chess.

With a half-point lead over GM Ray Robson entering Sunday, Nakamura silenced his last threat to the U.S. title by dropping 2006 champion GM Alexander Onischuk in a deceptively tricky endgame.

Meanwhile, in the Women's Championship, Krush pushed a draw against WGM Katerina Nemcova to capture an outstanding seventh title -- and fourth consecutive.
