I like the accuracy score question on a philosophical level: If we assume absolute determinism - meaning that if you have complete knowledge of all things in the present universe and true randomness doesn't exist - then yes. Given a certain goal, there would be a knowable, perfect series of steps to advance you towards that goal and any other series of steps would have an accuracy score < 100%.

But having absolute knowledge of the present universe is much easier to do within the constrains of a chessboard than in the actual universe.
