Queen and Knight vs Queen and Pawns Endgames
The Q+N vs Q+Pawns endgame is where one player has a Queen and Knight (and pawns), and the other player has a Queen plus some extra pawns. The material balance usually defines who is winning, with theoretical equality at Q+N vs Q and 3 pawns extra. Only one or two pawns is rarely enough.
Is 3 pawns enough? Although that’s the theory, in practice this ending is usually won for the Queen and Knight. If the King is in any way out in the open, the odds are high that the Queen and Knight will successfully attack the King long before any pawn gets to promotion. The defender could bring their Queen back to defend, but then advancing the promoted pawns becomes difficult. Alternatively, the player with only the Queen cannot really attack and deliver mate, although perpetual check is common. So in evaluating these positions, King safety needs to be an attribute that gets given a much higher value, perhaps worth as much as an extra pawn.
Queen swaps are a particular issue in these endgames. A Queen swap will convert play into a “Knight vs Pawns Endgame”. The player with the Knight would usually want to avoid the Queen swap, to retain attacking play with Queen and Knight, unless the Knight really can hold up all of the extra passed pawns. The player with passed pawns will often do well to exchange Queens.
