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. The first examined game, played just days before I am writing these lines, illustrates the latter idea.} 1. d4 Nf6 2. g3 d5 3.
