Would help slightly if pictures were in colour, but isn't essential. Lots of pictures demonstrating each move, allowing it to be studied and practised easily. Very informative, the beggining section on stances and set ups are very useful.
In the end a very informative and concise book, that teaches you how to takedown your oponent and gain the advantage. Its contents will be very useful for self defense aswell.
Well worth the buy and am already buying another book by the same person, and looking at others (savage strikes and killer subbmissions).
