The two bishop endgame is a great example of how well both the light square bishop and dark square bishop work together. The key concept is that white should strive to connect his bishops, activate his king, and gradually force the black king to the back rank. You should not be looking to put the king in check until you have the black king comfortably trapped along the back rank. Only then can you seperate your bishops and prepare for the checkmate. With a little practice, the two bishop endgame will become one of the easiest endgames you will learn.
