What a system is
The London, and why repeating one setup saves more study than it looks.
You met the King's Indian Attack and the word SYSTEM appeared. Now it gets a lesson of its own, because it is the most important study decision for anyone who plays for pleasure. Ordinary opening: you learn to answer what your opponent does. System: you build the same setup and your opponent deals with it. Less memory, fewer surprises, more chess.
The London. The most played system in the world today, and you can learn it in five minutes.
The same London in a different order: the bishop comes out on move TWO, without waiting for the knight. This is how most people play it today. Follow it to the end and compare with the board above.
