However, this evaluation is relative and requires a concrete insight into the position. Firstly, the term of "bad bishop" mainly applies to endings where this piece fights against an enemy bishop or knight, without any other pieces on board. This important aspect is frequently overlooked. Secondly, depending on the concrete pawn configuration, the pawns blocked on the same colour as that corresponding to the bishop, may actually ensure its stable control over the important diagonal. In certain cases, this could allow the effective king's intrusion, but more typically it has meaning in endings with other pieces on board, for instance one rook on each side.

Fridrik Olafsson (Island), Amsterdam (Euwe Jubilee) 1976 In May 1976, to mark the occasion of the 75th birthday of the 5th World Champion, Max Euwe, a four-player, double-round-robin grandmaster tournament took place in Amsterdam. The venue for the event was the Vincent Van Gogh museum in the city's Museumplein. The participants were World Champion Anatoly Karpov (USSR), Walter Browne (USA), Fridrik Olafsson (Island) and Jan Timman (Netherlands). Karpov was in fine form in the event, and going into the final round he needed only a draw v. Olafsson to secure clear first place. However, as he later explained in his notes to this encounter (published in his autobiographical Izbrannye Partii 1969-77), in such situations the draw should be achieved from a position of strength. As in his game v. Wolfgang Uhlmann from the final round of the international tournament at Skopje a couple of months previously, the Soviet grandmaster played strictly according to the situation on the board, and scored a fine win. The game appears in Volume 21 of "Chess Informant" with notes by Karpov. Regarding the circumstances of the game v. Olafsson, Karpov later wrote in his "Selected Games" (Izbrannye Partii): "The tournament situation obliged me not to lose - in this case I would occupy 1st place. A task that is seemingly not so difficult, when playing with White. This does not at all mean that it is necessary "to play for a draw". Not under any circumstances! Then the chances of losing are very great. This truism is known to many chessplayers (but not many can follow it!). It is necessary to play as one always does, but then, at the critical moment to recall that for general victory a draw is also sufficient." 6th round, Amsterdam (Euwe Jubilee), 21st May 1976} 1. e4 c5 2.
