1. d4 Nf6 2. Bf4 g6 { As you can see, our Opponent is going to Set up Kings-Indian. The London is good enough against it, but we can also play a fierce attacking variation with our London. As such I recommend delaying the move e3, and putting the b1 Knight out. Later, we do not have to play e3, we can go for e4... [%cal Gb1c3] } 3. Nc3 { ... because our Knight will be guarding the pawn. Black will most often than not put his dark-squared Bishop on g7, where it will be controlling a lot of squares (potentially a1-h8!), but we do not have to worry: We have the d4-pawn, which is for now defended with our Queen, later it can be defended with our other Knight... [%csl Ge2][%cal Ge2e4,Gc3e4,Rf8g7] } ( 3. e3 Bg7 4. Nc3 ) 3... Bg7 { [%cal Rg7d4,Gd1d4] } 4. e4 { Now we are controlling more space then our Opponent. We can push the pawn e4 to e5 and this our strategic plan, but we do not need to do it fast, we can simply wait and see what our Opponent is doing. If we are able to push the pawn to e5 (and even if we trade the pawn), our Knight will be able to go to e4, which is a excellent square for any Knight (note, that the enemys Knight is controlling e4) [%cal Ge4e5,Gc3e4] } 4... d6 { A natural move; which hinders our centre-expansion (at least, for now üôÇ) } 5. h4 { "Now this is attacking" We are just gonna push our h-pawn and attack on the King-side, in case our Opponent wants to castle short, he either is facing a massive attack or he has to make commitments, creating his own weaknesses we can target! Either way, we are happy [%cal Gh4h5,Gh5h6] } 5... O-O ( 5... h5 { Our Opponent hinders us on going forwards with our h-pawn. BUT: look at that g5-square: it is a nice outpost, we can use for our pieces (especially the Knight!!) more on that later... [%csl Bg5][%cal Bh4g5] } ) ( 5... Nc6 6. d5 ) 6. h5 { So, our Opponent has castled on the very same side we are attacking... That is risky, considering that we wanted him on this side to attack him! [%cal Gh5g6] } 6... Nxh5 { Yes, we "sacrificed" a pawn for the attack, but look at Blacks King and his pieces! Most of his pieces are on the other side of the board and not helping out the King... [%csl Ra8,Rb8,Rc8,Rd8,Gg7,Gf8,Gg8,Gh5][%cal Bh1h5] } ( 6... Nbd7 { If black does not react to our threat, we are going to take the g6 pawn } 7. hxg6 ( 7. h6 { h6 is also good, the Bishop will have to move and the King can not seek safety on g7 } 7... Bh8 { Now we would break open the cntre, after all the black King-side has a weakness! } 8. e5 { [%cal Re5f6,Re5d6] } ) 7... fxg6 { Even now, the blck King and the King-side have weaknesses: the light-squares! But we do not have to rush } 8. Nf3 ( 8. Bc4+ { [%cal Rc4g8] } 8... Kh8 ) ) ( 6... Bg4 { [%csl Rg4][%cal Rg4d1,Gf1e2] } 7. Be2 { [%csl Gd1,Ge2][%cal Gd1h5,Ge2h5] } 7... Bxe2 8. Qxe2 ) 7. Rxh5 gxh5 8. Qxh5 { Even an exchange down, we have mighty attacking potental!!! üòé } 8... e5 { e5 forces us to commit either to capture the pawn with our d-pawn, or it questions us, where we are going to move our Bishop. We should capture indeed with our pawn } ( 8... Bxd4 { Now we are an exchange and a pawn down, but still we have good attacking chances! } 9. O-O-O { [%cal Rd1d4] } 9... Bg7 { [%cal Gg1f3,Gf1c4] } 10. Nf3 ( 10. Bc4 ) ) 9. dxe5 { Now our Opponent has to react, if he captures with his d-pawn, he blocks out his own mighty Bishop or he takes back with his Bishop, in that case we would take the Bishop with our own Bishop; in this variation, we would be very, very happy } 9... dxe5 { [%cal Rg7e5] } ( 9... Bxe5 10. Bxe5 dxe5 { You see, our opponent has several weaknesses: For one, he has a hanging e-pawn (we can take), then he has a very open King and he also has very little piece developement [%csl Re5,Rg7] } 11. Qxe5 ( 11. Nf3 { We can also simply add another attacking Force to attack the weakness, also the Knight can join a King attack if necessary [%cal Rf3e5,Rh5e5] } ) ( 11. Rd1 { [%cal Rd1d8] } ) 11... Nc6 12. Qg3+ ( 12. Qh5 ) 12... Kh8 ) 10. Rd1 { Just simply developing while attacking the opponents Queen, what is not to like? üôÇ [%cal Rd1d8] } ( 10. Bxe5 Bxe5 11. Qxe5 { Now we have access to the dark-squares (especially around the enemys King) } 11... Nc6 12. Qg3+ Kh8 { Now we can develope further, we can put our Knight into the centre, we can move our rook to the open d-line and if necessary, we can strengthen our e-pawn [%cal Gc3d5,Rf2f3,Ba1d1] } ) 10... Nd7 ( 10... Qe7 { If the Queen steps aside, we can put our Knight into the centre-and this for free! } 11. Nd5 { Now our Knight has a very nice outpost, is attacking the Queen and is a little closer to the enemys King, just in case... [%cal Rd5e7] } 11... Qe6 { The enemys Queen wants to help her monarch, we can choose to get our Bishop to safety or to get back the exchange through a fork! (note, that we sshould not give up 2 pieces for the exchange, as such, we do not need to go for the rook in the corner!) [%cal Bf4e3,Gd5c7,Rc7e6,Rc7a8] } ( 11... Qd6 12. Bg5 { We simply move our Bishop to a nice square (it is out of danger and controls the nice diagonals c1-h6 and d8-h4) [%csl Gg5][%cal Gg5c1,Gg5h6,Rg5d8,Rg5h4] } ) ( 11... Qc5 12. Bh6 ( 12. Nf3 exf4 { Now this is a blunder, because of... } 13. Nf6+ { THIS! We would be up a Queen... [%cal Gh5c5] } 13... Bxf6 14. Qxc5 { ...but our opponent has nice Bishop and a rook for the Queen, which is not bad...(But still, we got a whole Queen!) } ) ) 12. Be3 ( 12. Nxc7 { [%cal Rc7e6,Rc7a8] } 12... Qg4 13. Qxg4 Bxg4 { [%cal Rg4d1] } 14. f3 { We are attacking the Lightsquared-Bishop aswell as the rook, our own Bishop is still attacked and it could be possible, that our opponent gets a "dragonesque" Bishop, e.g.: [%cal Gf3g4,Re5f4,Gc7a8] } 14... exf4 { Do NOT rush to take the rook, it is already trapped and the Bishop is still hanging üôÇ } 15. fxg4 { [%csl Rg7][%cal Rg7b2] } ( 15. Nxa8 Bd7 { [%csl Gd7][%cal Gb8d7] } 16. Nc7 ) 15... Nc6 { Black wants to recapture his rook } 16. Nxa8 Rxa8 17. c3 { c3 is strong, because the Bishop on g7 is more or less blocked out: the Bishop can not take a pawn, nor can it check our King, to add to this, the Knight can not move forward! [%csl Bb2,Bc3][%cal Bb2c3,Bc3b4,Bc3d4,Rc6b4,Rc6d4,Rg7d4] } ) ) ( 10... Qf6 11. Nd5 { As we have seen already, it is pretty good to develope the Knight, while attacking the Queen, while defending the Bishop and while threatening a rook } 11... Qd6 12. Bg5 { [%cal Gg5e7,Gd5e7,Rd1d6] } 12... Qe6 13. Nxc7 { Now we would be heading into a similar variation, but this time it is even better for us üòé [%cal Rc7a8,Rc7e6] } 13... Qc6 14. Nxa8 Qxe4+ 15. Be3 ) ( 10... Qxd1+ { Our opponent is giving up the Queen for two Rooks, because he will take our hanging Bishop. And although two Rooks are slightly more valuable then one Queen, the pieces of our opponent are mostly not developed or uncoordinated } 11. Kxd1 { It is recommended to take with the King, because he could help out defending pawns, there is nothing to fear really (Rook checks are "nothing", really ) and our Queen is placed nicely and active, we sshould not retreat this powerful piece! } ( 11. Qxd1 exf4 ) 11... exf4 ) 11. Bg5 { This Bishop move questions the enemys Queen, either our opponent needs to move their Queen or create another weakness } 11... f6 { [%csl Gf1][%cal Gf1c4] } 12. Bc4+ { As you can see, our light-squared Bishop, that was "sleeping" up to this point, is now awake and a great attacking force, after all, black has a very weak King (the light- and dark-squares around the King are not great defended, mostly the light-squares though!) [%cal Rc4g8] } ( 12. Be3 { We can also retreat our dark-squared Bishop! } ) 12... Kh8 { This move is forced } 13. Be3 { ... and now we retreat our Bishop to safety üòé } *
