What this lesson explains
You are ahead. Now the hard part is to win. Three rules help. Trade pieces, not pawns, because every trade makes your extra material count for more. Take away your opponent's tricks before you go for more. And do not hurry: a safe move is better than a fast, risky one.
What you practise
You are a knight up. Black's queen is the only piece that can still make trouble, by hitting b2 and f2. The two queens face each other. Trade them.
You are two pieces up for two pawns. Black's only hope is the c-pawn, two steps from a new queen. Stop it first, and only then go for more.
You are a pawn up, with two pawns against one on the queenside. Rook endgames are often drawn even a pawn up, because the defending rook stays active. Pawn endgames are much easier to win. Trade the rooks.
Worked examples
You are a knight up. Black's queen is the only piece that can still make trouble, by hitting b2 and f2. The two queens face each other. Trade them. Good. With the queens gone, Black has almost no tricks left, and your extra knight decides the game.
You are two pieces up for two pawns. Black's only hope is the c-pawn, two steps from a new queen. Stop it first, and only then go for more. Good. The pawn cannot get through, and your back rank is safe. Now you can win the black pawns one by one.
