I recommend that anyone looking to have some mischievous fun at chess  should take up the the Budapest as an occasional surprise weapon. I found  this book at a used book store for $5 a few years back and my investment  has been paid back a 100-fold. The Budapest is great for quick kills versus  weaker or similar strength players. A gross example: White N. N. (1600) - Me  (2000), 1998; 1. d4 Nf6 2. c4 e5 3. d5 Bc5 4. Bg5?? Ne4! and white resigned  after a few more moves and I was soon relaxing at Hardees while my  competition was grinding out four-hour games. Of course 5. Bxd8 loses  instantly to. Bxf2#. Boryk's book is much more easily absorbed than  Tseitlin & Glaskov's, Budapest for the Tournament Player, with its  head-spinning variations and transpositions. Instead, Boryk offers numerous  games with ideas and strategies for Black. Nevermind that this opening is  not popular with the GM set where they have everything memorized out to  20-25 moves. This is a great opening for chess improvisors and tacticians  out here in sub-master land that like to mix it up. If you can get this  book at a bargain price -- pick it up!
