What is the London system

I am tired of playing queens gambit and I want to try something new. I've heard talk about the London system but never really cared about it. Can anybody tell me what it is and maybe some traps if black plays mistakes

SCOTCH!! e4 e5 Nf3 Nc6 d4!!!!!

of course. best opening ever as white

I can only say if you want to play the London System, you need to study it some. It's not a specific opening, but rather a more generalized system that had certain similar opening moves, particularly the early move of bishop to f4. After that, the games can vary quite a lot in the moves, but after you learn the basics, you'll get a feel for how it all works. You don't need an  encyclopedic knowledge of opening moves in the system, that's why it's popular. But one does need to get some sort of training on the basics though. I tried to do the Londen System without really getting any books or computer training for the system and pretty much failed badly.

I just don't have time right now to delve into the Londen System, but I hear is pretty good.

You play the London when you are too scared to play a real opening. You give black all the initiative and die a slow death, then go home and tell yourself that at least you gave black a game.

Here is Nakamura's take...starting at 30:28, although he doesnt start in on the London until 31:46, finishing at 33:08 with his final assessment. That assessment being he has to self-censor what really thinks of it for family audience sake.

London system is a crutch for bad players. Play a real opening.

"... I think it's worth examining why I used to do so badly against [the London, the Colle, the Torre, the Trompowsky, the Veresov, etc.] ... I didn't actually have a repertoire at all against, say, the Colle. You just play chess, right? Develop the pieces and equalize. I remember Grandmaster Vlatko Kovacevic playing the Colle against me ... Time has mercifully obscured the details, but I know I went ... d5 and ... c5. Pretty soon a knight appeared on e5 and I didn't seem to be able to shift it. Shortly after that, either the h- or the g-pawn arrived on the premises. Then came Re3, Qh5, and the next thing I knew I was looking like something out of 1001 Winning Chess Combinations. That wasn't the only such debacle, either; every time my opponent played one of these vile things I was behind on the clock as I worked on my conception of the wheel, and just as you'd expect some of my wheels came out square. ... I didn't consider [these openings] dangerous. ... I could list easily a hundred 2550+ players who have succumbed to the openings ... These openings produce as red-blooded a struggle as any, and if you're not ready for it, you're starting at a big disadvantage. ..." - IM John Cox (2005)

In Post#3, you managed to insult the entire nation of Scotland by calling their beloved Scotch Game the "London System!" You probably insulted England as well
