How do I spot a discovered attack in a middlegame?

How can I find a tactical refutation in the Sicilian Defense?

Start by checking forcing moves and identify loose or overloaded defenders. In many Sicilian Defense positions, open lines and active pieces create opportunities for forks, pins, skewers, and discovered attacks. Compare every candidate move against the opponent’s immediate tactical threats.

What is the difference between a skewer and a pin?

A pin attacks a less valuable piece that cannot move because a more valuable piece is behind it. A skewer reverses the order: the valuable piece is attacked first, and when it moves, the piece behind it is lost. Both motifs rely on alignment along a rank, file, or diagonal.

How do I calculate a winning combination in chess?

List your forcing candidates, beginning with checks, captures, and threats. For each one, calculate the opponent’s most forcing response and then identify what remains attacked or undefended. A combination is winning when the resulting material or positional advantage survives the opponent’s best defense.

The key lesson is that an apparently attacked piece may have a powerful tactical resource.
