Jobava London

Put the knight on c3. Know what that commits you to.

1. d4 d5 2. Nc3 Nf6 3. Bf4

Choose the Jobava if you like active piece placement and are willing to calculate early central tactics. It is not simply a sharper label for the same London setup. The catalogue includes trap-oriented Nb5 lines, which are useful exercises but should not be mistaken for a guarantee that Black must permit a fork.

Three ideas to remember

Nc3 gives activity while restricting the c-pawn

The knight helps control d5 and e4 and can jump toward b5. In exchange, White cannot freely support d4 with c3 or challenge the centre with c4. This makes e3, piece support and central exchanges especially important. Learn the new structure instead of trying to build the standard London pawns around an occupied square.

Bf4 and Nb5 can coordinate against c7

With a bishop on f4, a knight on b5 may threaten to enter c7. Black can prevent or meet the idea through development, pawn moves or central counterplay. The potential fork is a reason to calculate, not an instruction to play Nb5 every time you recognise the opening.

Central moves can interrupt a wing threat

Black's ...e5 can attack the f4-bishop and challenge d4 while White is looking at c7. Those threats may change which capture comes first. When several pieces are attacked, work through forcing replies in order rather than choosing the most attractive-looking fork immediately.

Turn the structure into a plan

White's plan

White develops the light-squared bishop and kingside knight, supports the centre with e3 when appropriate, and decides whether the c7 pressure is real. The active c3-knight can help a later e4 break if the pieces support it. Keep king safety in the plan: an early knight excursion is less convincing if it leaves the rest of the army unused.

Black's plan

Black should identify the Nb5 possibility before placing pieces automatically. Control b5 when useful, support the centre and watch for a forcing ...e5 break. If White spends time attacking c7, development and central activity may be more important than hanging onto every pawn. Calculate whether moving the king or returning material removes the immediate danger.

Common mistakes

Taking c7 without checking the opponent's threats

The catalogue's Rook Win Tactic demonstrates Nb5 and ...e5, followed by a knight fork. This is a particular line in which Black's king can move to d7. Before copying it, check what ...e5 attacks and whether Black has a stronger reply in your position. A named rook-win line is not a universal attacking recipe.

1. d4 d5 2. Nc3 Nf6 3. Bf4 Nc6 4. Nb5 e5 5. Nxc7+ Kd7

Forgetting that c3 is already occupied

The standard London often uses c3 to support d4 and places the knight on d2. The Jobava cannot make that same pawn move while the knight remains on c3. Mixing the plans can leave d4 inadequately supported or the pieces obstructing one another.
