What do you think of the Colle System

Magnus carlsen once said that to get to wesley so's level you only needed tactics, but to get to world championship contender level you'd need more.

And this is how to beat the Stonewall, but it still only works when white diverts his rook into an attack. The problem with the rook lift is that you can't do it if you have an escape hole for your king, but if you don't have an escape hole, this can happen. The machine gave me 92.8% and the Review only about 86. I think the accuracy should be between 97 and 100 but maybe that's a bit overly 'opeful.

I mean the general way to beat the stonewall is to maintain tight control over e5 if possible, sometimes white wants to play cd5 but a lot of the times he should simply expand on the queenside at an opportune moment. If black's dark squared bishop is traded off then he's usually worse at best.

A kingside attack in the stonewall usually involves pawns, and not using pieces only like what your opponent did in the game.

Not control over e5 but control over e4. Controlling e5 isn't so important in the initial stages. The Qc8 move has a triple purpose. It supports Na6 and the e6-f5 diagonal but also it makes a Ne5 ineffective. Although I've found that it's just as playable if black allows a Ne5 to fork black's Q and remaining B, because white just wastes moves and the Ne5 is potentially more useful in attack against f7 than swapping itself for the e7 bishop.

So the strategy for black is to swap off the light squared bishops and then get knight control over e4 by rerouting the a6 knight. White's remaining bishop is weak and slow to get into the game. It's white who is struggling to draw, as happened here.

I play the Colle usually is my main weapon.

Just a few examples: https://www.chess.com/c/Kbodjcpv

I was talking about a Dutch stonewall not a reversed stonewall, hence e5 and all the other stuff about dark squares bishops. But yes

The Colle is aggressive

Oh right. Got you.

Ask yourself .... is the Semi-Slav potentially aggressive? The point is that it's so compact and flexible. The c1 bishop acts like an extra, moveable pawn that eventually becomes a bishop but the fact that white doesn't develop it outside the pawn line means there are no targets for black.

The Colle is very aggressive. White gets a violent attack once he has pushed e3-e4 after proper preparation. Here is another example:

colle is literally a reversed semi slav, so congratulations, you've played yourself.

In what way **isn't** it a reversed Semi-Slav?

1. d4 ... d5 2. Nf3
is the correct move order for the Colle and black probably plays 2. Nf6, because white could be heading for a London or a queens gambit.

So  ...Nf6
3. e3 and now black may go c5. Speaking for myself, I would play c5 at that point most of the time. Occasionally I may play e6 but c5 seems a good move and I do tend to play it. It being a good move.

If black doesn't play good moves though, isn't white in a better position still? The idea of the Colle is that depending on the position, white either prepares e4 or prepares an attack on black's king after black goes 0-0. Sometimes both. The Botvinnick Variation isn't the only aggressive variation of the Semi-Slav, after all.

here's the colle setup and semi slav setup. Oh boy. I can't wait to start listing the differences!

Yes there's no comparison at all. Completely different. Black's winning hands down too.

They don't aim for an opening advantage, sure, but that doesn't really matter all that much.

The London used to be mainly a defence for black against the King's Indian Attack.

London is just annoying

and to all london players, plz play something thats actually interesting and not just random bishop moves

cope + stay mad + skill issue
