HiTech won the 1985 and 1989 editions of the [[North American Computer Chess Championship]].<ref name="A:G"/> From September 1985 to July 1988, it used the same hardware, while its standing in the US chess community rose from being in the top 2% to the top .5%. Berliner described this change as a result of "using better management of the resources that have been available."<ref name="A:C">{{Citation |last=Berliner |first=H.  |title=International Workshop on Industrial Applications of Machine Intelligence and Vision |date=10–12 April 1989  |chapter=Hitech chess: from master to senior master with no hardware change |pages=12–21 |publisher=[[IEEE]] |doi=10.1109/MIV.1989.40515 |chapter-url=https://ieeexplore.ieee.org/document/40515 }}</ref> In November 1985, the [[Associated Press]] reported that over five months of play, it had earned the rank of master and achieved the highest rating ever given a chess machine. At that time, its developers argued it was 50% faster than any other chess-playing computer systems.<ref name="A:P">{{Citation |last= |first= |date=November 24, 1985 |title=Computer Knows the Right Moves, Is Master at Game of Chess |work=[[The Los Angeles Times]] |url=https://www.latimes.com/archives/la-xpm-1985-11-24-mn-1654-story.html}}</ref> The computer began competing on the chess circuit, only going against humans, in 1986.<ref name="A:H"/> By 1987, the computer ranked 190th in the United States, and was the only computer among the top 1,000 chess players.<ref name="A:I"/>

ChipTest was invited to play in the 1987 American Open, but the team did not enter due to an objection by the HiTech team, also from Carnegie Mellon University. HiTech and ChipTest shared some code, and Hitech was already playing in the tournament. The two teams became rivals.<ref name="atkinson">{{cite book|last=Atkinson|first=George|title=Chess and Machine Intuition|year=1998|publisher=Intellect Books|isbn=0893919012|pages=175}}</ref>
