Foreword

This chess book amazes me. Firstly it is not

annotated by a human, it is annotated by Houdini

Chess Engine. It has no recommendations or

contributions from any titled chess player. What

makes it relevant is the single fact that it was

made by a group of ordinary people who love

chess and want to play chess, share chess and

discover chess with like-minded people.

This breaks the rules but for all the right reasons.

Introduction

My earliest memory of chess was picking the book

“Alexander Alekhine Best Games” published by

Batsford. This book had a profound impact on me

and I read it from cover to cover and inspired me

to play chess and love chess more and more with

each passing day.

Levon Aronian is made of the same stuff as my

hero Alekhine and it seems fitting after all those

years I write a book about the Levon’s best games

in the style of my beloved book.

The book is divided into three parts like a chess

game it is seamless and interconnected with each

other part, but represents a distinct stage in our

Levon’s development

Every page tells a story of the genius of Levon

Aronian and speaks of the great beauty of

attacking chess. Enjoy
