you can buy it in the us too.

ZOOM is a book written Stefen Zeuthen along with Bent Larsen. In it is a proposed a system of play based on the Greunfeld Indian formation. (Catalan as White --as Black the Greunfeld and Center Counter with ...g6.)

The main point was the with pattern recognition, where you can lessen the need to learn openings. Also the pattern recognition is helpful in middlegame structures and endgames. So instead of learning one opening and two defenses (against 1 e4 and 1 d4), you learn just one pawn formation.

Another classical ZOOM pattern is the King's Indian Attack as White, and King's Indian Defense with the Pirc Defense.

I think the book title is odd but chess friends who own it say it's very good.
