Today, I`ll show you a game played by Alexander Alekhine and his opponent is Aron Nimzowitsch. This game has what we now know as Alekhine`s gun(the queen is behind the 2 rooks on the same file).
Alekhine`s gun was again used in 1936 against William Winter.
That picture above shows Aron Nimzowitsch.
Thx for viewing!
