What is an interference tactic in chess?

An interference tactic blocks or disrupts the line between an attacking piece and the piece it supports or targets. It often prevents a skewer, pin, battery, or other tactical connection from working.

How do I spot a skewer in a chess endgame?

Look for a valuable piece attacked first with a less valuable piece aligned behind it. Calculate whether moving the front piece exposes the rear target, and check for defensive interpositions or counterattacks.

What is a defensive move in chess?

A defensive move protects against an immediate threat while improving coordination or creating counterplay. Strong defensive moves may block an attack, defend multiple pieces, or force the opponent to exchange.

How does an overloaded defender work in chess?

An overloaded defender is responsible for protecting more than one important target. If the defender is diverted, pinned, or forced to capture, one of those targets may become vulnerable.

What should I calculate before choosing a quiet move?

List the opponent’s forcing options, especially checks, captures, and threats. Then verify that your quiet move addresses the tactical danger and does not leave another piece hanging.

Interference Advanced Puzzle (Rated 1277): Interfere — Defense

An interference tactic works by blocking or disrupting a key line between an attacking piece and its target. In this middlegame position, Black’s active rook creates a double threat against White’s queen and knight through a skewer. The correct defensive idea uses coordination to interrupt that line, preserve material balance, and neutralize the pressure. This is a useful practical pattern: when one enemy piece attacks two valuable targets, look for a move that obstructs its route or changes the geometry of the attack.
