Freeze & Ice-covered
So, if we had a supercomputer that could evaluate every possible line in chess, what would the probability be that it would always choose the optimal move? Let's break that down.
If it really looks at every line and picks the best, the chance it always plays optimally is one, given perfect evaluation and no mistakes. In short, 100%.
Got it, but in reality no system can guarantee 100% accuracy—there's always a tiny margin for error.
Right, even the sharpest engine has a minuscule slippage – just a fraction of a percent. The math says 100% only if every evaluation is flawless, but in practice you’re looking at 99.999% or thereabouts. So, almost perfect, but not absolute.
A tiny slippage turns the theoretical perfect into a razor‑thin margin, but that still means you’re essentially playing at machine‑level precision.
