Houdini 4 first went wrong with 76 b5. The program’s own analysis showed 76 Ne5, keeping the Black Knight out of f3, but for some yet as to be determined reason the program made the pawn move. Then on move 80, Houdini 4 melted down completely by trading a Rook for only pawn. Houdini’s analysis showed it was expecting 79…Ng5, but when Chiron 2 played 79…h5, Houdini 4 was obviously flummoxed. Chiron 2 showed 80 Nxh5 as best.

When asked what had gone wrong with Houdini 4 its handler said, “Today Houdini 4 passed the Turing test because it played like a human. As to why, we have just finished a psychiatric diagnostic of Houdini 4. The answer is on the screen.”

“HOUDINI 4 HAS CHIP ISSUES.”

When asked to elaborate, the plug was pulled.
