One of the most important positions to learn is those with opposite-coloured bishops. A chess player, wanting to become strong, needs to improve many different areas of the game. This might include, for example, playing positions with opposite sides castling, making positional pawn sacrifices, and playing with a knight against a bishop. Developing experience in this or that type of position enables a player to become better prepared and more confident when these occur in his games. It is also important as players can then decide to enter particular types of positions that they have studied before, for example, choosing to play with or against the isolated queen pawn.

Developing expertise in middlegames with opposite-coloured bishops can be very time-consuming. To do so you can read different manuals about middlegame play; most will have at least a chapter about such positions. There is also useful material on YouTube. You can also study the games of strong GMs and study the critical moments yourself or you can read this series of articles which the Modern Chess team provides you with! Any material is easier to learn if it is properly structured.
