Sneaky Pete,
an early chess program, and first chess computer to play in a U.S. Open, held in Columbus, Ohio, 1977 [1]. According to Harold Lundstrom's Deseret News article [2], it was far from the best of its class, good at picking up loose pawns, but with a bad habit of overlooking mates, in total winnning four and losing eight games. A 1977 USCF letter to Mr. John Griffin, published in Douglas Penrod's 1977 Computer Chess Newsletter, No. 2, Pg. 13, mentions Sneaky Pete with a rating of 1209 [3].

As much as Sneaky Pete would love to play 61...b5#, White has this forced en passant capture in reply, when his king will easily escape and Black's bishop will soon go lost. But Sneaky Pete came up with the brilliant 61...b6!!. Of course, White could just enter the winning line with 62.cxb6, but it isn't forced and he has a chance to blunder. And sure enough, White cooperated [4]:
