1. d4 d5 ( 1... Nf6 2. Bf4 { Once again we are starting with the accelerated London System. But this time we are going to set up the Jobava London System! In order to do so, we usually put our Knight out first, but have to expevt that we could transpose in to the frech-defense... So, we put out our Bishop and try to get a Jobava London without transpositioning. } ( 2. Nc3 { The main move in the Jobava London. You see, we can not, at least for now, advance our c-pawn: We can neither attack the center nor strengthen our center with whe c-pawn, but we have an excellent Knight, which supports the eventual center we are going to build. } 2... e6 ( 2... d5 3. Nf3 e6 ) 3. e4 { Due to our Knight we can push our e-pawn to e4, we now have a very beautiful pawn center, but... [%csl Ge4][%cal Gc3e4] } 3... d5 { Black can transpose into the frech-defense, and if we do not know how to fight this opening, we are -frankly- lost. Remember: The french is something completely different and we can kind of prevent the transposition } 4. e5 ) 2... d5 3. e3 Bg4 4. f3 Bf5 ( 4... Bh5 5. g4 Bg6 6. Nc3 { [%csl Gh5][%cal Gh2h4,Gh4h5] } 6... e6 7. h4 h6 8. h5 Bh7 9. Bd3 ) 5. g4 Bg6 6. h4 h5 ( 6... h6 7. h5 Bh7 8. Nc3 ) 7. g5 Nfd7 8. Nc3 ( 8. Bd3 ) 8... Nb6 9. Nb5 { [%cal Rb5c7] } 9... Na6 { [%csl Gc7][%cal Ga6c7] } ( 9... e5 10. Bxe5 { We simply take the free pawn, that is given with little to nothing of compensation } 10... Na6 ) ) 2. Bf4 Nf6 { The Rapport-Jobava London System's signature move is theis Knight jump to c3. The Knight pressurizes the center and controls some squares on the Queenside, BUT the c-pawn is not able to advance any time soon. [%csl Gc3][%cal Gb1c3] } 3. Nc3 c5 { Directly fighting for the center, we will simply push our e-pawn, to defend the pawn one more time and to activate our Bishop! [%cal Rc5d4,Ge2e3] } 4. e3 { Now our Bishop is active and we defend our pawn with another pawn [%cal Be3d4,Gd3b5,Gf1b5,Gf1e2,Gf1d3] } 4... e6 { [%csl Gb5][%cal Gc3b5] } ( 4... cxd4 5. exd4 { This is a good trade for us, because our dark-squared Bishop could slide back in the middle game and our light-squared Bishop can be activated, we also love the square e5, which can later be occupied by our Knight, also our other Knight pressurizes the center. [%csl Be5][%cal Bd4e5,Gg1f3,Gf3e5,Gf1e2,Gf1d3,Gf1b5,Rc3d5] } ) 5. Nb5 { [%csl Rc7,Ra8,Re8][%cal Gb5c7,Rc7a8,Rc7e8,Gf4c7] } 5... Na6 ( 5... Qa5+ { This Queen check is only helping our play, because our Knight is already developed and we get to push the c-pawn!üôÇ [%cal Ra5e1,Ra5b5] } 6. c3 { [%csl Gb5,Rc7][%cal Gf1b5,Rb5c7,Rc7a8,Rc7e8,Rf4c7] } 6... Na6 { The only way to defend the rook now, but the opponents pieces seem to be stuck at the Queenside rim defending our threats, this is grim (for our opponent) } 7. a4 Bd7 { We can ignore this move and finish developement or we choose to get the Bishop pair [%csl Rd6][%cal Rb5d6] } 8. Nd6+ { If Black wants to castle, he has to lose his dark-squared Bishop } ( 8. Nf3 { A good developing move } ) ( 8. Bd3 { A nice option } ) ( 8. Be2 { Another choice } ) 8... Bxd6 9. Bxd6 { As long as this Bishop is not threatened to be captured or similar, it will be a powerful piece in the enemys territory, hindering our opponent to short castle üòé [%cal Rd6f8,Rd6c5,Rd6b8,Rd6g3] } ) 6. a4 *
