Interference
Key Concept
Place a piece on a square to break the coordination between two enemy pieces
How This Tactic Works
Interference is a subtle but powerful tactic where you place a piece on a square that disrupts the connection between two enemy pieces — typically breaking the line between a rook and another rook, or between a queen and a defending piece. By wedging a piece in between, you prevent one piece from supporting the other. If the interposing piece cannot be captured without major consequence, the disruption often leads to material gain or checkmate. This tactic is more common at the advanced level and frequently appears in endgame studies.
How to Spot It
- →Two enemy pieces defend each other along a rank, file, or diagonal
- →You can place a piece on a square between them that cannot be easily captured
- →The disruption of their coordination leads to a decisive threat
Practice Tips
- →After each game, review positions where a Interference was possible — either you played it, your opponent played it, or it was missed by both sides.
- →Focus on the key signal: Two enemy pieces defend each other along a rank, file, or diagonal. Train your pattern recognition until you see this automatically.

What is the key signal that a Interference is possible?
The clearest signal that a Interference is on the board is: Two enemy pieces defend each other along a rank, file, or diagonal Other patterns that often precede a interference include You can place a piece on a square between them that cannot be easily captured; The disruption of their coordination leads to a decisive threat. Training your eye to spot these signals is what separates players who calculate tactics from players who miss them.
Is the Interference good for beginners to learn?
The Interference is rated Advanced because it usually requires multi-move calculation and an awareness of subtle positional cues. It is worth studying once you have mastered the basic tactics (fork, pin, skewer, discovered attack) and you regularly reach middlegames where these advanced patterns surface — typically around 1600+ rating. Below that level, your time is better spent on the fundamentals.
How do I train myself to spot Interference patterns?
Three steps. First, solve themed puzzles — search a free puzzle site for "interference" or filter by the Defensive Errors category and do 10–20 a day until you can solve them instantly. Second, review your own games and tag every position where a interference was possible — whether you played it, missed it, or your opponent missed it. Third, do blindfold pattern recognition — set up a position from memory and ask "where is the interference here?" This builds the calculation muscle far faster than passive study.
