Im preparing for club championship match. i need help please. My opponent FIDE 1645 always opens with D4 and Bf4. I Play Nf6 against d4 but i dont know what to do against Bf4, can somehelp please. I know it is called the London system but i am looking for a good response against it.

Thanks

Did you try looking in the Games Explorer?

Here is the system I employ against that setup.

Thanks ill give it some thought

What about a sharp line against it?

Why don't you avoid it altogether and play the Albin Counter-Gambit?

That's similar to what I would play, except I play d5 on the first move.  The problem I have with that sort of position is what to do next. 

i dont have a book on albin or london system but thanks for the advice. keep it coming. :)

If you like to play the KID, then you might consider g6 with a potentiality of going into the Boring System.  There really aren't that many sharp systems against the London.  It is very drawish.  I can compare it to the Exchange Slav without the Exchange if that makes any sense whatsoever.  Anyways, if he is better than you, a draw with Black would make you happy.  If he presses his chances, then you should be able to take advantage of that.  Hope this helps!

Yeah it helps a lot thanks. what exactly is the boring system? Iv got a few book on the KID.

Here's something I found in my note file for 1.d4 Nf6 2.Bf4...

[2... d6!  Immediately blunting the 'London Bishop'. 3. e3 g6 4. Nd2 Bg7 5. h3 O-O  KID treatment. 6. Ngf3 Nbd7 Taking advantage of d6. 7. Bd3 b6 8. O-O Bb7 9. a4 a5 10. c3 Re8 A potential e5 break forces White to move his bishop again. 11. Bh2 e5 12. dxe5 Nxe5 13. Be2 Arfert-Lange, Recklinghausen 2002, 0-1. ]

thanks likeforests that was very helpful. when we get to move 8 black has a very solid structure and that is what im looking for as he is stronger than me.

This is the main line...                          

Hope it helps!
