Definition & Meaning of "Alekhine's gun"

What is "Alekhine's gun"?

Alekhine's gun is a powerful chess tactic named after former world champion Alexander Alekhine. It involves aligning two rooks on the same file, one directly behind the other, with the queen positioned behind them. This formation creates a strong attacking line, allowing the queen to support the rooks and apply significant pressure on the opponent's defenses. The tactic is particularly effective when the opponent's king is on the same file, as it can lead to decisive attacks.
