Endgame: Knight or Bishop

Have you been in a situation where you are about to choose between knight or bishop in an endgame? I will give you some hints about the knight and the bishop. To begin with, there are two types of endgames, one is what we called the Open game and the other is the Closed game. In open games, i will suggest that you will give more importance on Bishops than knights. When you combine bishop and a pawn during an endgame, you will create a very strong offense and defense mechanism. But when it is a closed game, it'll be good that you choose the knight, the hook of the knight is very useful in attacking the tight defense of your opponent. The king can't hide to an aggressive knight. Therefore choose wisely. :)
