On his preliminary round he was admitted as ex-aequo winner of the 2nd Prize on the 2015 Polish National Fryderyk Chopin Piano Competition in Warsaw. He was stopped in the third stage of the XVII International Chopin Piano Competition in 2015. Although Krzysztof Książek was not qualified for the finals of the Chopin Competition, Andrzej Sułek believes that his name may return to the competition in those days.
