Nineteenth century American prodigy Paul Morphy never wrote anything about how to play chess, but his games are sparkling examples of classical chess principles at work. He had a talent for discovering magical moves that wound his opponents up in knots -- check, check, and mate out of nowhere. How did he do it? Everyone agrees that it was his insight into principles and his tactical genius that allowed him to dominate the greatest masters of Europe in his day. So, a book of Morphy's games would be entertaining and inspiring. But Frisco del Rosario has done more than compile brilliancies from Morphy's games -- he uses carefully selected games as case studies to illustrate principles enunciated by chess writers such as Fine, Horowitz, and Purdy. On the one hand, you have a principle, such as "Develop with threats" and on the other you have an application, "Morphy vs. Duke of Brunswick and Count Isouard." The back and forth between principle and illustrations is well-choreographed and told in a lean and lucid manner. The beauty of this approach is del Rosario's choice of games to illustrate the principles -- they are all crystal clear. The cumulative wisdom of the principles themselves form a unified approach to good chess. Very helpful are del Rosario's explanations of tactical sidelights that informed the decisions of Morphy and his opponents. Some authors go overboard on this and leave you mired in detail. Not in this book. The text, like the games of Morphy, moves quickly. Read it and play through the examples for enjoyment, and you'll feel the effects next time you're faced with a decision over the board.
