Alekhine's gun:

Alekhine's gun is a formation in chess named after the former World Chess Champion, Alexander Alekhine. This formation was named after a game he played against Aron Nimzowitsch in San Remo 1930, ending with Alekhine’s decisive 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
