Chess Opening Theory/1. d4/1...Nf6/2. Nc3/2...d5/3. Bf4

Jobava London D01 Rapport-Jobava system Chigorin variation 3. Bf4 · Jobava London Sometimes referred to as the Rapport-Jobava System. This opening serves as a good surprise weapon against unprepared opponents, and in the worst case, equalizes. White often plans to threaten a knight fork on the c7 square after Nb5, usually played on the fourth or fifth move. Black typically challenges the center immediately with /3...c5/ and trades their c-pawn for White's e-pawn. Alternatively, Black often plays the /3...a6/ Anti-Jobava to control the b5 square or the natural /3...e6/ development move. Black may also attempt /3...Bf5/, developing the light-squared bishop before playing 4...e6, but it gives White an opportunity to launch a pawn storm with a tempo on the bishop through a well-timed g4 push (usually after White plays f3 or Ne5, protecting the g4 square).
