Chess Endgame Strategy - Top Ten Principles
#1 - Activate your King. It is an invaluable attacking piece in the endgame.
#2 - Create a passed Pawn, and escort it to promotion.
#3 - When ahead in material, exchange pieces but not Pawns.
#4 - Place pawns on opposite coloured squares as your Bishop.
#5 - Put rooks behind friendly and enemy passed Pawns.
#6 - Use Rooks to cut off the enemy King.
#7 - When you have the advantage, don't waste time promoting multiple new Queens. Press your advantage for checkmate instead.
#8 - Activate and coordinate your pieces before making premature Pawn thrusts.
#9 - Develop threats and passed Pawns on both wings.
#10 - When you have the advantage, simplify to a winning endgame.
