I came accross this eBook on Bill Wall's site offthewallchess.com. Bill Wall is a well known chess writer and his book '700 opening traps' is available as a free download from the website mentioned above, as well as his many other books and articles.
The following examples are taken from the chapter dealing with some traps in the Queens Gambit Declined. I've made working examples (thanks to chess.com) as a guide only, to help show you what you can gain from reading the book and working through the notation.
Thanks again to the author of '700 Opening Traps' (Bill Wall) for allowing me to upload the book to chess.com!
