4.5. Endings of Opposite Coloured Bishops
In endings of opposite coloured bishops the strategy is vitally different since the bishops cannot attack or defend the same points. This makes the role of the king much more important; whilst one pawn advantage is in most cases insufficient for a win since the advance of one passed pawn can be prevented very easily. In accordance with the fundamental didactic principles, endings of opposite-coloured bishops may be divided into the following groups: Bishop and one pawn vs. bishop Bishop and two pawns vs. bishop Bishop and three pawns vs. bishop Bishop and one pawn vs. bishop and one pawn Bishop and two pawns vs. bishop and one pawn Bishop and three pawns vs. bishop and one pawn Bishop and two pawns vs. bishop and two pawns Bishop and three pawns vs. bishop and two pawns Bishop and three pawns vs. bishop and three pawns More complex endings of opposite-coloured bishops.
4.5.1. Bishop and One Pawn versus Bishop
Bishop is completely “useless” in this type of endings since it is unable to support its pawn in advancing past the barrier created by the enemy bishop so the weaker side draws easily. Play unfolds as in endings of pawn against bishop. Consequently, these endings are generally trivial and unworthy of attention. Nevertheless, two studies of small practical but considerable artistic value, in which the weaker side draws in a curious manner, deserve attention.
