How do I spot a discovered attack in a middlegame chess puzzle?

What is the Accelerated London System and what tactics does it create?

How do I know when a sacrifice is worth it in classical chess?

A sacrifice is usually justified when it wins back material, wins the queen, or creates a decisive attack. Check whether the opponent’s king becomes exposed and whether their pieces are tied down. If the resulting position gives you active pieces and forcing moves, the sacrifice may be sound.

What is a hanging piece in a chess tactic?

The key idea is to use a forcing sacrifice to drag a defender away, then exploit the exposed queen and loose back-rank coordination. In positions like this, activity and king safety can outweigh static material concerns.
