Sometimes the move immediately before the one with the big score is not a
mistake - the side to move may be already lost, and have no good alternatives.
But neither side sees this earlier, due to limitations in the depth of the
search. So you really need to back up a few moves and analyze what happened in
the positions leading up to the one that seems decisive.

Another factor to consider is just how long you want to analyze, both for the
discovery of possible tactical mistakes and the confirmation of them. Something
that looks good (or bad) at depth 10 may look different at depth 15. You can't
usually be 100% certain that you have a unique best move.
