Maybe.  I use the term to refer to cases where you find the answer to a
tactical test for positional reasons, which could also be referred to as
"tactical instinct" or perhaps, uncharitably, "luck", but perhaps you
could also sniff a great positional move the same way.

A sniff is when you find a Bxh2+ sacrifice but your score is +0.04.
