Home * Engines * Grok

Grok means to understand so thoroughly that the observer becomes a part of the observed — to merge, blend, intermarry, lose identity in group experience ~ Robert A. Heinlein [1]

a private chess engine developed by Peter Kappler, written in Java, development actually inactive [2]. Primary board representation is mailbox. Grok averages around 250k nps in the middlegame on an Athlon 1400 [3].


Grok is a neologism coined by American writer Robert A. Heinlein for his 1961 science fiction novel Stranger in a Strange Land, to indicate a concept of self transcendent experience and emergent identification beyond those of many "subject-object" assumptions. It has since become a widely used word to indicate intense or profound understanding [4].
