Alekhine’s gun is a formation in chess named after the former Russian World Chess Champion, Alexander Alekhine. This formation was named after a game he played against another illustrious Latvian Grandmaster, Aaron Nimzowitsch in San Remo, Italy, 1930, ending with Alekhine’s victory.
The idea consists of placing the two rooks stacked one behind another and the queen at the rear.
This can lead to massive damage to the opponent as it usually marks the beginning of the final assault (in Nimzowitsch’s case it was only four moves before his resignation).
In very rare cases it can be two queens and one rook on the same file.
Six years later, in 1936, William Winter was defeated by Alekhine in Nottingham, who used Alekhine’s gun again to secure the victory.
Since then, chess players have learned much about using and guarding against this formation.
However, some international games are still lost and won by the force of this classic chess tactic.
