Not exactly.
I cannot put the real definition of this setting in two words, so I simply named
it "anti-human". Look, could you guess what an airbag does just by its name if
you did not know what it is?
Antihuman is designed to avoid closed positions. When Antihuman is ON, Tiger is
able to detect an opponent trying to close the game. If the opponents tries to
keep the game closed and antihuman is ON, Tiger will sacrifice up to one pawn if
necessary to open the game in the opening/middlegame, and up to one KNIGHT in
the endgame.
This setting is supposed to be used against players who are known to 1) close
the game completely and 2) move a piece back and forth until the programs loses
on time.
This trick has been used for a long time against chess programs on the chess
servers, and antihuman has been designed to address this.
I suppose I should rename this setting "anti closed positions"?
