What are some strategies for endgame?
Often times simplification is a common motif of winning an endgame, but this alone is not always best. The key is to have an understanding of the theoretical endgames and which ones are won, lost, or drawn. Then you simply have to assess how to transform this current position into an endgame favorable to you. For example: one theoretical endgame that is a must-know for any serious chess player is King + pawn vs King. Sometimes a draw and a win look similar to an untrained eye. Knowing many endgames well will help you know what your endgame goals should be.
