Jobava London System

If you want to know how to do this, here’s the trick.

Do you know the Ruy Lopez or Italian Game? The Italian Game is just the Ruy Lopez with BC4 and the Ruy Lopez is just the Italian Game with BB5. 
But the Veresov Attack is the Ruy Lopez with the queen’s pawn. The Jobava System is the Italian Game version of the Veresov.

The Ruy is stronger than the Italian by quite a long way. But the Jobava is stronger than the Veresov-Richter Attack, since black has very effective play against the Veresov due to the position of the Bg5, which is left hanging in some lines. That play isn't available for black after Bf4.

The main reason that the Jobava London is currently more popular than the Veresov, is that white's main strategic threat in the latter (Bxf6) is basically a bluff.

Yes it is, although I found that the line 3. ...Nbd7 was very effective, to be followed by ....c6 and in the case of 4. f3 then Tal's e5 pawn sacrifice. I never found any forced line for black leading to saving the game but in practice got a lot of wins with it and very rarely lost. Most players returned the pawn with e5 - e6, which was still difficult for white. The tactics depend on the white pawn on e5 being pinned against the Bg5 when black's Q is on a5. I lost otb playing the Jobava as black a few months ago against a booked up player around 2100. He played the very tactical line involving pawn advances on the k side, I got one important decision wrong in time trouble and was crunched.
