Junior (chess program)
Junior is a computer chess program written by the Israeli programmers Amir Ban and Shai Bushinsky.According to Bushinsky, one of the innovations of Junior over other chess programs is the way it counts moves.Another approach its designers claim to use is 'opponent modeling'; Junior might play moves that are not objectively the strongest but that exploit the weaknesses of the opponent.According to Don Dailey ″It has some evaluation that can sting if it's in the right situation—that no other program has.″[2] In 2003 Deep Junior played a six-game match against Garry Kasparov, which resulted in a 3–3 tie.These programs opted out of the World Computer Chess Championship, which was held at the same time and won by Rybka with a score of 10/11.
