Ingo Althöfer,
a German mathematician, computer scientist, game researcher, game inventor, and full professor at Faculy for Mathematics and Computer Science [2], Friedrich Schiller University of Jena [3].
Ingo Althöfer's professional as well as private research interests cover a broad range of AI-issues, search algorithms, evaluation, creating and inventing new, interesting games such as EinStein würfelt nicht! [4] [5] , and triple-brain (3-Hirn) (two- or k-best mode, where an arbiter instance choses from the best moves provided by one or more chess-programs) [6] [7]. 3-Hirn has become a "brand name" for books, games and software, distributed by Ingo's small publishing company 3-Hirn-Verlag. Along with his former student Timo Klaustermeyer, he introduced the concept of freestyle chess within a Blitz tournament in August 2004 [8] [9].

3-Hirn's Motto
By Christian Posthoff and Günter Reinemann 1987 [12] [13] :
Nicht
Der Mensch kann, aber die Maschine nicht...
oder
Der Mensch kann nicht, aber die Maschine kann...
sondern
Der Mensch kann, aber Mensch und Maschine zusammen können (viel mehr).
Not
Humans can, but machine can not...
or
Humans cannot, but machine can...
but
Humans can, but humans and machine together can (much more).
