How do I spot a pin in a chess middlegame?

Look for a piece that cannot move safely because a more valuable piece stands behind it. Check whether moving the pinned piece exposes the king, queen, or another major piece to attack. Relative pins can still win material even when the king is not involved.

What is a skewer in chess?

A skewer attacks a valuable piece first, forcing it to move and exposing a less valuable piece behind it. Queens, rooks, and bishops commonly create skewers along open files, ranks, and diagonals. Always check whether the attacked piece is protecting something behind it.

How does a discovered attack work in chess?

A discovered attack occurs when one piece moves away and reveals an attack from a queen, rook, or bishop behind it. The move can be especially strong if the moving piece captures something or creates another threat. Look for aligned pieces before calculating forcing moves.

In this Sicilian Defense middlegame, Black exploits the coordination of White’s pieces rather than launching a direct kingside attack. A bishop is pinned relative to a more valuable piece, while the queen creates a skewer against another target. The key tactical idea is to move the pinned bishop with tempo, uncovering a second attack and forcing favorable exchanges. This type of winning combination is especially powerful when one move activates multiple threats and leaves the opponent unable to protect everything.
