1.e4 — the open games
French Defence, Fort Knox Variation
1.e4 e6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bd7ECO C10
An ultra-solid Rubinstein French: Black plays …Bd7–c6 to trade off the traditionally bad light-squared bishop, reaching a rock-solid, almost unbreakable structure. Nicknamed 'Fort Knox' for its impregnability — a favourite of players who want a safe, low-theory answer to 1.e4.
Key ideas
- …Bd7 and …Bc6 exchange the French's problem bishop, leaving Black with a sound, harmonious position.
- Black completes development with …Nd7, …Ngf6 and …Be7, and is very hard to break down.
- It concedes a little space for near-total solidity — safety over ambition.
Who it suits
Solid players who want the safest, lowest-theory way to meet 1.e4 with the French.
