Converting advantages : Knight endings
This is a difficult topic, because knight endings are in general quite difficult, because of the amazing amount of squares that a knight can reach.
There's probably a bunch of rules of thumb for knight endings but here's a few I could just think of right now :
1. Knight endings tend to be quite difficult. Don't go for a knight ending if you are not sure about how the evaluation of the position is.
A pawn up in a knight ending with both a knight and several pawns on both wings does not guarantee the win. It all depends on knight and king activity and how weak (or not so weak) the pawns are.
2. Pawns on the edge of the board (a and h pawns) are usually difficult to stop by a knight.
The knight often needs a few moves before it can stop a pawn on the edge of the board.
3. A knight can do amazing miracles to stop a single passed pawn only supported by the opponent king, which can lead to unexpected draws.
It is often better to have a few isolated pawns or connected pawns, rather than one single passed pawn where the king must support the promotion of that pawn.
Let's have a look at a few games.
