How do you destroy the London opening

I want to know how to destroy the London system because it is really annoying

Thank you

Three key moves for black in the London are Bf5, c5 and Qb6.

And no matter what White’s next move is, Qb6. Easiest way to equalize against the London.

I play nf6 sooo

The London is a very sound system. You are not going to "destroy" it

Can’t really destroy the opening as the person above me said. But I would recommend either a system with e6, c5. Or immediate c5 Qb6

You can't really "destroy* it but what I do is I try to make some weird moves to take them out of their comfort zone, even if it's bad for me I'm still more comfortable than the london player

Ah yes, dxc5 Qb6 is a rly interesting line

I think 2...c5 is the best. Here's some lines to it.

If white plays 2.Nf3 first, I play it in a slightly different move order:

What do you think about 6. Na3 ?

It’s good if Black takes, but Black doesn’t have to, and then your knight is stranded on a terrible square, and there isn’t a whole lot of room for improvement either, c2 is terrible, and c4 or b5 are protected.

When I used to regularly play the London, I pretty much never saw 6.Na3, so I just didn't mention it.

But yeah, as @Ethan_Brollier mentioned, black doesn't have to take. 6...c4 and black is doing fine.

Lol after 6… c4 one of White’s ideas might be an eventual Qc1 Nb1 Nbd2 to reroute the knight.

After c4 I saved in my database this line (can't remember what source that was from).

Interesting line, I'll look into it.

1.dxc5 Qb6 2.cxb6 bye bye queen

A tricky but fun way to play against the London is to adopt a Hedgehog/Queen's Indian structure and go for ...Re8, ...Bf8.

I learned about this after seeing Carlsen do it a few times.

From here, Black has the flexibility to prepare a pawn break on e5, d5, or even b5 ... depending on what White plays.

An example continuation of how White can go wrong fast:

It's not the easiest way to play against the London ... it's actually a bit challenging. But it's also challenging for White, too. Especially when a lot of London players are used to having the e5 square as an outpost.

Against 2.c5 white could play 3.c4 and turn it into a fusion of a London , Queens Gambit and Reversed QGD : Austrian Variation . This would reignite the Queens Gambit Opening Trap only much better and faster as 1.d4 d5 2.Bf4 c5 3.c4 dxc4 4.e3 b5 5.Qf3 Nc6 6.Qxc6+ Bd7 7.Qxc5
