Dariusz Świercz began learning the game of chess at the age of three. By the time he was 11 years old, he had already become a FIDE Master. He rapidly succeeded in obtaining his International Master title in 2008 by the age of 13, and then went on to became one of the youngest grandmasters in history and the youngest Polish grandmaster of all time when he was only 14 years old in 2009. Świercz won the 2011 World Junior Chess Championship at the age of 17 and is currently the only Polish male chess player to accomplish this title. The following year he also won the Under-18 World Championship. He favors the Sicilian opening for both white and black pieces, as well as the Ruy Lopez for white.
