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. Michael Mkpadi Chess Enthusiast

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.
