Eternal jumper
In chess, an eternal knight is understood to be a knight who has settled on a weak field of the opponent and can no longer be questioned . It is the special case of an outpost . A definition by Kurt Richter is that the well-positioned and well- protected knight “cannot be attacked by any enemy pawn and cannot be forced to exchange by any enemy stone of equal value”. An eternal jumper often gives his side a decisive advantage.
example
In this position, White is losing, because his bishop is much weaker than the black Eternal Knight. Since the pawn on a6 is lost and White has no counter-chances, he decided to give up after the next move.
