Forewor

d

This chess book amazes me. Firstly it is

not annotated by a well-known

Grandmaster or chess celebrity but by a

combination of chess engine, chess fans

and public comment and conversation. It

has no recommendations or contributions

from any titled chess player.

This breaks the rules but for all the right

reasons.

Introduction

Fabiano Caruana is a chess

phenomenon. In an age where

hyperbole in chess is commonplace

he is definitively the genuine article.

What is special about Fabiano is that

he has an attacking flair and liking for

conducting the chess struggle with all

the force and fire power available to

him but with the patience and

circumspection of a strategic player.

Attacks seem to develop in Fabiano’s

game as suddenly as the opportunity

presents itself having been playing

“normal” and “decent” chess up to

that point he shifts gears to Awesome.
