Secrets of Modern Chess Strategy: Advances since Nimzowitsch Book

I've been flicking between Watson's update on chess thinking since Nimzowitch and Sammy Reshevsky's The Art of Positional Play and the difference between the two is a chess education in itself. While Reshevsky's opening premise is largely derived from the theories of Wilhelm Steinitz, the first world chess champion, Watson stresses the importance of actual analysis of actual positions over general rules, which he argues is what distinguishes today's top players from the rest. As always he writes in a clear yet erudite way that engages as it teaches.
