On the one hand, it's impudent to put together a couple of commented chess games and call it an opening book. If Mr. Burgess would have bothered to open ANY opening book published in the former Soviet Union, he would have seen what a decent opening book looks like. (There are even translations available.) Since he probably won't stoop to that (because the greatest chess nation on Earth is, of course, England), I better explain what I mean.
1. One thing that an opening book can't do without is system. Though Mr. Burgess has succeeded quite well in arranging the games in his book in a logical sequence, the reader will still have to write down his own variant tree with page references if he ever wants to find his way out of the Burgessian maze.
2. An opening book is supposed to analyze both good and bad sides of a variant. It is not considered solid to attempt to sell one's stuff whatever it takes. The title of Mr. Burgess's book is too pretentious, not to say misleading. Morra gambit (who's that Smith guy, anyway?) is by far not as powerful as Mr. Burgess claims (or as his sometimes not very thorough analyses attempt to show).
On the other hand, this incapable work, unfortunately, is the best source of information on Morra gambit I have seen. (However, I've been out of the active chess life for a few years, so there might be better books available today.) That's the first reason why I can't help giving it four stars. The second reason is that Morra gambit seems to be aggressive player's most promising way of avoiding Sicilian. I have experienced devastating disasters with b4 variants and, after that, played mostly 2. c3, which is, of course, a bit to passive. A few times I have played 2. c4; however, that is not quite my style. (You really should try it, if you like closed positions!) My first results with Morra aren't too great but it looks much better than anything else.
One thing I especially liked about the book was the introductory chapter which explained the main ideas of the Morra gambit. Well done!
If you are desperate to find an aggressive way of defending yourself against the perversity called Sicilian Defense, you really should consider Morra gambit. This book will give you a good start. If you're just curious, don't waste your money on Mr. Burgess before he has gained some experience on writing chess books.
