In the Star Trek universe, cadets attending Starfleet Academy must take the Kobayashi Maru final exam. Because the test is rigged so that no cadet can successfully save ship and crew, the point of the exam is simply to observe the cadet's decisions while in a command situation. Similarly, chess grandmaster Garry Kasparov had the supercomputer Deep Blue to keep him humble. The supercomputer was developed by IBM and was supposed to be as good as any human at the age-old game of chess. Kasparov had bragged that no computer could beat him, but Deep Blue managed it. Years later, however, some scientists now believe that Deep Blue's victory was actually due to a programming bug.
According to one of Deep Blue's programmers, at one point the computer couldn't decide what move to make, and it ended up making a self-sacrificial move that seemed overly sophisticated to Kasparov, making the grandmaster nervous. The program was tweaked so Blue couldn't repeat the mistake, but Kasparov was already shaken by the move and it affected his mental game and subsequent play decisions. Deep Blue dominated the second game.

At the topmost world level, any play is always a psychological game. Also, nobody could ever win in that level without a strong psychological mental state. So it may be considered as a trick also.
