'''Fail-Hard''' is a term related to an [[Alpha-Beta]] like [[Search|search]], to make [[Alpha]] and [[Beta]] '''hard''' [[Bound|bounds]] of the returned value of the search. Even [[Terminal Node|terminal nodes]] which indicate draw or mate scores are supposed to be adjusted on the hard alpha-beta bounds.
