Opposite-Colored Bishops

With bishops of opposite colours the attacker must play to keep the bishops on the board while building a second weakness; the defender blocks with his bishop and trades everything else. The attacking bishop belongs on the colour of the defender's weak squares. The chapter, with its further middlegame studies, shows the standard methods of both sides.

Black will not be able to break free in two directions: the seventh rank and the a2-g8 diagonal. Black's defense is very difficult.

The same problems plus a distant passed pawn that will tie down both black pieces. White have a technical win.
