Nunn's Chess Openings is written by a team of experts -- four writers who are acclaimed as outstanding chess writers and experts in their fields. The expert team's collective knowledge and experience covers all openings. Each section is written by a player with expertise in that area, enabling Nunn's Chess Openings to provide the sort of insider knowledge that can only be gained by playing an opening against tough opposition.Setting it above the rest, the majority of game references are from the 1990s. Computers have also been used to make the book extremely accurate: full use has been made of databases of millions of games; tables have been generated from computer files, eliminating notation errors, impossible variations, etc.; powerful analytical engines have assisted with the analysis of tactical positions; a final blundercheck has made sure there are no wrong moves given.
