Knight endgames

In a knight endgame with many pawns what is the strategy to win? 

What are the general rules?

Like in an endgame like this for an example..

First we have to ask who is on the move. A general rule is, imagine the Knights off the board. If you can evaluate the King and Pawn ending as win/loss/draw, you can most likely evaluate the Knight and Pawn ending. Rare exceptions, I've had them.

Ty.     Sometimes its hard to tell who will win the pawn ending tho.

i recommend the Averbakh series. GM Yuri Averbakh wrote or co-wrote all but one of the eight volumes. The Soviets tried to solve all potential endings in simple forms. Rook Endings (Authors are Smyslov and Levenfish), Pawn Endings, Knight Endings,  Bishop Endings, Bishop vs. Knight Endings, Queen Endings, Rook vs. Minor Piece Endings, Queen vs Rook/Minor piece endings. Broken down into few pawns, many pawns, positional advantage, etc. My copies are in Englsh Descriptive notation, hardback.

Are you in the market for the whole set? I know someone with the whole 8 volume set for sale in English Descriptive for $240 Priority mail, shipping and insurance included. He also has the 5 volume Averbakh set from Pergamon Press, 1983, Algebraic notation. The 8 voumes are combined to 5, and updated from originals. $360 Priority mail shipping and insurance included. Those prices are if you pay through Venmo. If paid thrugh Paypal, add 4%.

Search Amazon. See what individual books go for.

There aren't many rules and ideas in king and pawn endgames (or knight endgames). At least none that make it easier to play. It's just a lot of calculation.

One general tip for any simplified endgame like this... if your piece can't somehow come into contact with weak pawns (and the opponent's can) then you're very close to lost or already lost. Activity is extremely important. So one of the first things you can do is look for the base of pawn chains, isolated pawns, and capturing a pawn as a sacrifice to create a passed pawn.

So for example in your diagram, the knight on c4 can't be driven away, it will perpetually attack the weak a3 pawn, which when captured will create a passer. Ideally you notice the potential for something like this even before entering into the knight endgame.

thanks for the answers.
