Anderssen's Opening Pin in Chess
Anderssen's Opening Pin is a tactical motif where a piece (often a bishop) pins an enemy piece to a more valuable target behind it, creating immediate pressure. In Anderssen’s Opening, this typically arises after early development that places a bishop on a diagonal aligned with the opponent’s king-side or central structure, so the pinned piece can’t move without consequences.
To spot Anderssen's Opening Pin, look for a bishop line that suddenly becomes “loaded” on a diagonal after a forcing move—especially when an enemy piece sits between the bishop and the king, queen, or a critical defender. Use it by making the pin count: follow up with a move that either wins material if the defender can’t respond, or increases the pressure on the pinned piece until it must break the pin on unfavorable terms.
Frequently Asked Questions: Anderssen's Opening Pin
- What exactly is the “pin” in Anderssen's Opening Pin?
- It’s when a bishop (or another line-piece) attacks a piece and that attacked piece is unable to move because it would expose a more valuable target behind it, such as the king or queen.
- Which move or feature usually creates Anderssen's Opening Pin?
- The defining feature is an early bishop diagonal that becomes aligned with the opponent’s king-side or central pieces after Anderssen’s Opening development, so a key defender ends up sitting in the line.
- How do I exploit the pin—should I always try to win the pinned piece?
- Not always. First check whether the pinned piece is truly immobile (moving would lose the king/queen or a decisive tactic). Then choose the follow-up that increases pressure—often forcing concessions or enabling a tactical win rather than grabbing immediately.
- What’s the best way for the opponent to respond to Anderssen's Opening Pin?
- Common defenses include breaking the pin by moving the pinned piece if legal, interposing a piece on the bishop’s diagonal, or challenging the pinning piece with a tempo-gaining move so the attacker can’t convert the pressure.
