I'd recommend the classic The Art of the Attack by Vukovic. It's available in paperback for about $17 new and $5 used from Amazon. You can find it in pdf here http://bellairechessclub.com/sites/default/files/vukovic_vladimir-art_of_attack.pdf
and in chessbase and pgn format through Everyman's ebook page. https://www.everymanchess.com/ebooks/art-of-attack-in-chess
Here's one review: http://www.chess.com/article/view/book-review-art-of-attack-in-chess
I wish to learn the ultimate art of attacking the King. Pawn storms, etc. Everything I can. Any suggestions? I will of course be using the content here on Chess.com as well. Wanting books as a supplement kind of thing and I like holding things in my hands.
