Cray Blitz was the first computer to win an "open section tournament", back in 1981. Yet it should have lost to a 1700 player in that event, as he had it down to -3 at one point, but a single mistake let the machine escape with a win. Computers can put up a "better than real life" result from time to time. It doesn't mean they are super-GM players however. After the 1981 event, people started taking CB (and computers in general) more seriously and things got much more difficult after that.
