The bishop and knight endgame is one of the most challenging endgames that you will study. Both pieces have a defined role and with proper play, it’s a beautiful endgame. The problem is figuring out how to balance both pieces and and winning in under 50 moves (or the game is a draw).
A few things to remember is that you should aim to drive the king into the corner of the same color that your bishop is on. The easiest way to do this is to force the king to the back rank and then slowly force the king down to the corner. Try not to focus on checking the king and instead try to focus on surrounding the king, and limiting his moves.
