How do I spot a bishop and knight mate in classical chess?

What is deflection in a chess puzzle?

Deflection is a tactic where you force a piece away from an important defensive duty. In mating attacks, the defender may be pulled off a key square so the king becomes vulnerable. It is especially powerful when the defender is guarding escape squares or protecting a critical piece.

Why is the Queen's Gambit Declined common in tactical puzzles?

How do I find a mate in 2 in a middlegame position?

What attacking ideas work against a castled king?

Common ideas include sacrificing to open lines, deflecting a key defender, and controlling the squares around the king. Bishop and knight coordination is especially dangerous when the pawn shield is weakened. Always look for checks that force the king into a cramped position.
