You can watch the analyse of the game as a video aswell: www.youtube.com/watch?v=V3wzoWAakAA In this game you will see one of the most typical plans in the Jobava London System by the man himself. In this concrete game it doesn't only lead to an positional advantage for white, but also to a clear winning position. Anyway as you can see on the result, Jobava still lost the game. Take it as a word of warning: Stay focused until the game is over!1d4Nf62Nc3d53Bf4c54e3...4.Nb5?now doesn't work because ofQa5+5.Nc3cxd46.Qxd4Nc67.Qa4Qxa48.Nxa4e5and black is much better.4...Nc6?4 moves played and white is already winning. Even if this was just a blitz game it shows that even grandmasters can fall for this trick. You may say, that this is only one example and you don't belive that this will occur in one of your own games, but I herewith guarantee you, that you will have it in your own games! To undermine my point I checked my Lichess games and until now I had the position 13 times on the board! Not bad if you ask me.
Anyway its white to move and win!
Tip: The field c7 is pretty weak.4...cxd45.exd4a6is known as one of the main variations for black.4...e6?!is another common move by black, that leads to a nice position for white after the moves5.Nb5Na6Whites plan is pretty simple. He will play c3, a4, Bd3, Nf3-e5, 0-0 and probably even h3, while black finds it hard to find a plan. It's not that easy for black to gain his Knight on a6 in the game because of the threat Nc7+. It's also hard for black to move his rook on a8 because then the pawn on a7 would be hanging.5Nb5!...Remember that move! Whenever black plays c5 in the Jobava London System you should automatically think about it because in most of the cases it's a good move.5...e5Virtually the only move. Some players tryed5...Qa5+but it will transpose to what we will see in the game after the moves6.c3e57.dxe5Ne48.Qxd56dxe5...6.Bxe5Is also ok, but 5 times less played then the mainmove. It could follow:cxd4and now white has two main options.7.Nc7+Kd78.Bxf67.exd4Nxe58.dxe5Ng49.Qxd5Bb4+10.c3Qxd511.Nc7+Kf812.Nxd5Bc513.Nh3Nxe514.Nhf4White is an easy pawn up but black has the Bishoppair. I think white is still better, but the position is not hopeless for black.6...Ne4Now white has another nice little tactic. Try to find it.6...a6is the main move for black. The following moves are not that hard to find, but you should know them, so you dont mess up the position.7.Nc3Now we threatening to take the Knight on f6 and if he moves away, then we could simply just win the pawn on d5. So black has to playd48.exf6dxc39.Qxd8+Nxd810.bxc310...gxf611.Bd3Ne612.Bg3Bd713.Nf3and white is a pawn up, with good bishops in a position where both sides have a slightly ruined pawnstructure. Just try to remember that whenever black is going for b5 in this position you should think of the counterstrike c4. Your white bishop is also well placed on the a8-h1 diagonal.10...Bd7If black trys to sacrifice the pawn on g7 just simply develop.11.Bd311.fxg7Don't take the pawn on g7 because afterBxg7you're still better but black gets some kind of counterplay.gxf6Sooner or later black has to take the pawn and then we will transpose to the line we allready saw.7Qxd5Qa5+7...Qxd58.Nc7+Kd89.Nxd5g510.Bd310.Bg3Nxg311.hxg3Nxe5is absolutely fine for white aswell, but I just like the other move.gxf411.Bxe4fxe312.f4And white is clearly better. Beeing allready up a pawn, white will win the black pawn on e3 too.8c3g5?!Black trys to complicate the game for practically chances. Even if it's a slight error, the position was allready lost so I can totaly understand why Quparadze played this move.8...a69.Nd6+9...Bxd69...Nxd610.exd6Be611.d7+Bxd712.Bc4Be613.Qe4Nd814.Bxe6Nxe615.Qxb7Rd816.Nf3White is winning.9Qxe4gxf410exf4a611Nd6+Bxd612exd6+Kd8Threatens Re8 pinning the queen.13Be2Re814Qxh7Nd415Kf1...This move was played by Jobava and is for sure not a bad move. Anyway even better was.15.Qxf7for example:Nc2+16.Kd2Nxa117.Qf6+Kd717...Re718.Qxe7#18.Bg4+Kc619.d7+Kc720.dxe8=Q
