Chess Informant 148

Every quarter of every year, a 55-year-old publication arrives at the desk of the biggest names in chess.

The readers of this quarterly magazine include world chess champions and their team of seconds…top 100 grandmasters…and highly sought-after trainers.

It may not surprise you that the average Elo of this publication’s subscribers dwarfs the competition — with Anatoly Karpov (peak 2780), Garry Kasparov (peak 2851), Vladimir Kramnik (peak 2817), and Vishy Anand (peak 2817) among its most loyal readers.

On the other hand, you might be surprised to discover that — despite the legendary feats and sheer playing strength of its readers — only a relative handful of club players know about the magazine’s existence…much less the competitive edge it provides.
