Everything is like a coin toss in a physical world. For instance, you turn on the light switch and the light comes on. Or does it? Perhaps the bulb is burned. Perhaps the power grid is down. Perhaps there is a fault in the switch. There is a great deal of randomness in everything in the physical world. Randomness is deliberately built into chess programs. If they played in a completely deterministic way, once you figured out a way to beat them, you would win every time. For programs at the top, there is very little difference (according to measurements). I am convinced that we will never know which of the top programs are strongest. It should be easy enough to prove me wrong[*], but I doubt if anyone has the time or the will to even attempt it. [*] In theory. In practice, I think a quintillion hours of computer time will be hard to come up with.
