Japanese Researchers Build Rock-paper-scissors Robot That Wins 100% of the Time 114
slew writes "Although the robot technically cheats because it watches your hand and can recognize what shape you are intending to make and beat it before you even know what is happening. Apparently it takes about 60ms for you to shape your hand, but the robot can recognize the shape before it is completed, and only takes 20ms to counter your shape so the results appear to the human opponent to be virtually simultaneous. I wonder how difficult it would be to add lizard and spock to the mix.... ;^)."

However, it still cheats, as it always follows the human.

Of course it's cheating, it's subverting the rules of the game. The robot is showing its hand after seeing yours. The fact that it does so fast enough to fool human perception doesn't change this.
Your comparison with chess is invalid: Deep Blue plays chess according to the rules of chess. This robot, on the other, is not playing according to the rules of Rock/Paper/Scissors, therefore it is cheating.

Depends how you define win. It will win 100% if it means it never loses.
Of course, if you add ties to the mix, the win percentage will be much lower.
If it plays itself, it will probably continually tie itself. If you don't count ties, that's basically still "winning".
