In this video NM Dan Heisman describes the de Groot “Think Out Loud” exercise from de Groot’s book Thought and Choice in Chess. Much more about this exercise is discussed in Dan’s book The Improving Chess Thinker. de Groot’s work investigates how good players find moves in actual game situations (as opposed to puzzles, where they have a specific requirement which guides their thoughts).
