  chessgames.com: Does anybody know if this player is the same as Adri de Groot? The names match, but the 50 year hiatus makes us think that perhaps it's a relative, or a coincidence.
Dec-07-04  sneaky pete: <chessgames.com> It's a coincidence, two different people, probably unrelated. Professor A.D. de Groot, born around 1910, is the author of "Het denken van de schaker" (translated as "Thought and choice in chess" if I'm not mistaken) who did research for this work (a dissertation) during the 1938 Avro tournament. His career as a competetive player (strong amateur) was very short. Adri de Groot is a contemporary correspondence player, born around 1950 or later.

Mar-11-13  Eduardo Bermudez: His book 'Thought and Choice in Chess' is an important contribution to understanding how a chess master thinks !!
Oct-26-14  sneaky pete: His dissertation "Thought and Choice in Chess":http://dare.uva.nl/document/131466 (from http://dare.uva.nl/aup/en/record/30...)
Nov-04-14  cro777: On the occasion of <de Groot's 100th birthday (October 26th)> the Dutch institute Cito (the Central Institute for the development of tests and exams) paid a fitting tribute, with a simultaneous display by Jan Timman and a lecture on De Groot by Willy Hendriks.

De Groot's dissertation "Het denken van de schaker" translated as "Thought and Choice in Chess" is considered the most influential book about (cognitive) psychology in chess and had a great impact on cognitive psychology in general. One of the main themes in "Thought and Choice in Chess" is the difference between the expert (grandmaster) and the amateur.

In his book "Move First, Think Later" Willy Hendriks has dedicated a chapter to the role of De Groot in chess psychology:
