This is another volume in the Dangerous Weapons series. At 223 pages, this is a pretty straightforward book. For those who don't know what Dangerous Weapons books are, I will give a short definition. Dangerous Weapons are ideas in different openings that the authors have extensively analyzed. In order to be counted as Dangerous, they must be off the beaten track, often weird, or complicated, or extremely ambitious. Anyway, of the book's weapons, 6 are for white and 6 are for black. The authors did a good job, the analysis is sound, and there are no typos. In general, the options for white appear on the board much earlier than the ones for black; for example, two of white's options appear on move two, while black's weapons don't appear until (on average) move 6. This makes it more useful for white players who like to deviate early, while it gives black extra options in the main lines (doesn't that make the whole book an argument for the early deviations it advocates for white?). Why only 4 stars then? Simply put, it's not amazing. It's a good book, a great book, but it doesn't sweep me off my feet. Looking for an option for white against the Dutch? Check out this well-written book.
