3. Knight and Pawn (s) vs. Pawn (s)
When the stronger side in addition to the knight also has one or more pawns, the win against one or more pawns is usually quite simple. However, there are many exceptional cases where the weaker side may avoid defeat in a study-like manner. Considering the essentially different strategy in different types of position, we may divide these endings into four basic groups:
Knight and One Pawn vs. One Pawn
Knight and One Pawn vs. Two Pawns
Knight and One Pawn vs. Three Pawns
Knight and Two or Three Pawns vs. More Pawns
3.3.1. Knight and One Pawn vs. One Pawn
Knight and a pawn usually easily win against a pawn. In case of a passed pawn, the stronger side may employ one of the two basic winning plans: Block the enemy pawn by the knight while supporting the advance of own pawn by the king, or Protect own pawn by the knight from the rear and attack and eliminate the enemy pawn by the king. Problems in converting advantage into victory may arise only when the weaker side has a very distant passed pawn and the stronger side a rook’s pawn. When the stronger side has a rook’s pawn, the weaker side defends by stalemate and may save the game only if its very far-advanced passed pawn has reached the second rank.
