Qiyu Zhou: Pattern Recognition in Chess

Another interesting chess study by Canadian WGM Qiyu Zhou published on ChessBase. Here she revisits experiments from 1925 by Djakow, Rukid and Petrovsky (later repeated and reported by de Groot) which compare chess players of varying skills at their ability to recall positions ranging from a common opening tabiya, to complex middlegames and endgames, to completely random positions. 

SPOILER: her results support the original conclusions, but there are two interesting outliers -- one being a chess master who is a Go afficianado, and scored much better at the random positions.
