I have used this book a great deal. The information is packed on to the page, and it is accurate. Grandmaster Vaiser covers all important lines and offers many original ideas. His suggestions have often become the main line theory. The only ommission that prevents me from giving this book five stars? It does not have the overview of strategy and planning we have come to expect from the very best writers.
