There’s the Fort Knox variation of the French: 1. e4 e6 2. d4 d5 3. Nd2 dxe4 4. Nxe4 Bd7 plus …Bd7-c6 to get that bishop outside the e6-pawn.
I had this thought: If you are a devotee of the Fort Knox (which Capablanca played once as a kid), oughtn’t you be inclined to deal with the Advance French 1. e4 e6 2. d4 d5 3. e5 with 3…a6 4…Bd7 plus …Bb5 when appropriate?
I consulted a database in which the Romanian master Dara has played the Fort Knox more than other players. Dara doesn’t go for 3…a6, but the related 3…Qd7 4….b6 plus …Ba6.
