Play Dirty (2006)

From the text:

Learn the worst, most despicable, dastardly and downright dishonest game mastering tricks, traps and tactics that will make you the GM your players love to hate!

John Wick's monthly game master advice column in Pyramid was the most controversial in the magazine's history. It was seen by some as revolutionary and dismissed by others as outright dangerous. Collected here for the first time are all eleven episodes including "Hit 'em Where it Hurts," (the Gaming Outpost article that served as a prelude to the mayhem that was to come), a new introduction and closing statements by the author.
