Queen vs Two Knights Endgame
White to play and win
PlayTwo knights are awkward defenders when they stop protecting each other, and here they do not: the king shields the one on c5, but nothing defends the knight on e7. Push the king to the edge and win one with a fork. But do not carry the wrong lesson away: two knights parked right beside their own king hold the draw, and no queen breaks it. This position wins because the knights are not protecting each other and you have the move: the same men with Black to move only draw.

The theory
Watch the method: press play to see the winning idea run, or step through it move by move.
Queen versus two knights is a win only when the knights stop protecting each other. Knights are short-ranged, and one that its partner cannot reach is one the queen eventually picks off. Beside their own king, though, two knights defend each other and shield every approach square: that formation is a fortress the queen cannot break.
The method. Bring the king up and use the queen to herd the enemy king toward an edge or corner. With the king boxed in, a check that simultaneously attacks a knight wins material.
The care. Watch for knight forks of your king and queen: keep your king on squares no knight can reach with tempo, and the pieces cannot hold together.
In this drill the knights do not guard each other and only one of them stands beside its king, so with the move in hand you convert. Corner the king, then fork a knight: the defender will jump into the most annoying squares, but knights that do not defend each other cannot save each other.
