I see extensions as takin a deeper look to some lines analyzed by the
machine, because the nominal search depth is likely to miss the outcome
of it. So i would extend a move only if there is a chance for a horizon
effect if not applying the extension.

The most obvious extensions: extend when in check, extend when mate threat.
Other possible extensions: extend when passed pawn races are happening.
