Interference Beginner Chess Puzzles

Interference beginner is a tactical motif where you place a piece on a critical square to block a line between an enemy piece and the square or piece it protects. The goal is usually to cut communication between a defender and its target, often on a file, diagonal, or rank. For an intermediate player, the key idea is that the blocking move itself creates the tactic, not just the threat after it.

Look for positions where an opponent’s rook, bishop, or queen is defending something from a distance and there is only one square that can interrupt that line. Interference works best when the blocking piece is protected, when the blocked line matters immediately, and when the opponent cannot simply capture the interposing piece without losing more. In your games, scan for checks, captures, or threats that force a defender onto a line you can then block.
