The London System begins with 1.d4, with an early Bf4, pawns on d4/e3, often with c3/c4, Bd3, Nbd2 and Ngf3. In this video we see two mid-level amateurs, with me – ChessCreator – playing White.
chess opening London System part 4 = kingside attack, delayed castling, quick checkmate

What would you do if they DID move the pawn to f3 instead of moving the Queen?

@ollie705 Cool. I think it's a very underrated opening. Feel free to send me some PGNs of your games, if you'd like me to video annotate 1 or 2.
Me too.
same offer goes to you …. (see above).
I like this idea, and though it's the first part I've seen of this series I have some questions. What do you consider to be Black's best way to play against the London system? I used to play Mason's opening (d4, Bf4) and sometimes Black would play Bf5 and at least back then it seemed like the games were very symmetrical and "balanced".
If Bf5, I switch focus to queenside (e.g. Qb3 targets b7.) – see video 8. I’ve not found a perfect anti-London set-up. I find well-timed c5 + Qb6, or Bf5 + early Ng8-f6-e4 can be tricky to handle. If black plays Bd6 (before c5), I avoid Bxd6 as Bxd6/cxd6, as that seems to gives black a good game. In Bd6 lines, I play Bg3 (Bd6/Bg3, Bxg3/hxg3) intending 0-0-0, using h-file, etc
This is a game I played using the London system.

absolutely loved this video! new to chess, but playing well above my level with the London System, thanks to your series of videos. keep up the great work! love your channel!
H3 is a hidden gem. + capturing with the pawn is crucial.
If anyone wondered, Houdini 1.5a (one of the very strongest engines) on my laptop evaluates this as a very stable game, with white retaining the 0.1-0.3 point "opening advantage until black's slight mistakes on the kingside start happening. White would be up roughly the equivalent of a pawn before the missed 15. ..f6, but because of f6 being so adequate, Houdini massively prefers 15. Nf3 rather than 15. Bg5, adding some more fuel for the attack. The Nf3 is followed by an h-pawn launch.
I think h4 straight away is better for an attack
so black need to play aggressive to prevent white from reaching the full system. any suggestion as to how to achieve this?
Pawn f6 is the best way to defend his black king but a lot of compensation,,, at white almost dominate the game
hey what about f6
Brillant London system You tube !
Many Thanks
Your opponent made a lot of blunders in this game. This quick mate doesn't usually work against experienced players.
Sorry to see that you played Qc7 instead of f6.. Too bad you didn't show the tactical shot after f6 than Bxg6!!! winning
why cant black play pawn to h6 to defend against the queen?
I really can’t understand who is white and black
4:31 i would panic, get an aneurysm and quite possibly explode
I first watched your wonderful London series many years ago. Since then I have won many many games with it. Thank you so much for making these video chess lessons. They are terrific! I am enjoying watching them all again.
