100 Repertoires London System by IM Alex Astaneh

Advantage Achieved!
Play Astaneh’s Adaptive London System

Drop the autopilot! It sells your first-move advantage too short. Try this London System instead — built by a 3-time Irish champ to fight for an edge in every game. It adjusts to Black’s setup, asks tough questions, and forces errors. All while narrowing your prep down to 106 essential lines.

You start with 1.d4 then you follow up with 2.Bf4.

You open with the London’s
most flexible move order

It locks the game into a London System.

But here’s the bigger deal — it keeps your d1–h5 diagonal open. So your queen can poke, prod, and punch dark-square holes into Black’s kingside.

With your queen’s diagonal open, you
can generate threats and secure an
edge on the dark squares

By holding back your knight, you also keep key tactics alive… like hopping from g1 to f4 to take out Black’s bishop pair, while dealing serious pawn structure damage.

Even with a minimalist repertoire, you
can play sharp and press harder for an
edge, thanks to Astaneh’s smart
line selection

And if Black challenges you head on? You’re quicker on the draw, with your bishop already posted on f4!

With this Bf4 London, you’re always
closer to castling queenside and
amping up your piece play

Let’s Walk You Through Astaneh’s London

Right after the intro, Astaneh sets you up for success with the Quickstarter chapter.

It covers the 14 core lines you must know. All surveyed in under 2 hours of video. So if you want to become a London System expert in a single sitting, you absolutely can!

Part 1 of the repertoire dives into Double Queen’s Pawn, 1.d4 d5. Here, you face the Slav and Semi-Slav, mirror structures, and classical setups.

And when Black plays the most natural moves, you lean on the classic London formula.

You rally everyone behind your d4-stronghold. So when your other central pawn finally breaks through, your pieces explode through the gaps!

The Classic London Plan in action:
Bishops out, knights connected… then
you light things up with e3-e4!

If 1…Nf6 is where you need the most help, then head straight to Part 2 of the course.

It covers the Grünfeld, Benoni, and Dutch Defense. But if Black plays the King’s Indian Defense? Now you might as well be winning — thanks to your ready-made attack on the h-file!

In this opposite castling position, the
King’s Indian Defense is in serious
danger of being blown away!

The final chapter brings everything together with model games.

Watch top GMs turn the exact lines you’re learning into a Greek Gift attack out of nowhere.

Go to chapter 20 and see how even
with reduced material, this Greek
Gift crashes through the kingside

Other times, it’s death down the long diagonal, or a queenside pawn majority marching to glory.

If you want to play the London System — not to get by — but to win…
