How do I spot a skewer tactic in a middlegame?

What is a tactical refutation in chess?

A tactical refutation is a forcing sequence that proves an opponent’s move or plan fails. It often uses checks, captures, skewers, pins, or discovered attacks to win material or establish a decisive advantage.

How can I find a hanging piece during a chess quiz?

First count attackers and defenders, then check whether the defender is pinned, overloaded, or unable to move. Compare forcing candidate moves before making a quiet capture. A hanging piece may only become vulnerable after a check or intermediate threat.

What is the difference between a skewer and a pin?

In a pin, moving the front piece exposes a valuable piece or king behind it, so the front piece is restricted. In a skewer, the valuable target is attacked first and must move, allowing the attacker to win the less valuable piece behind it.
